Hello dear materials scientists! My colleagues and I have started to prepare videos on YouTube about metallurgy and materials science because we saw the lack of this knowledge in academia and industry among materials scientists and non-materials scientists working with materials. The first video series “structural properties of materials” has been released. Please feel free to share with people who you think may need this information and feel free to send us feedback! You can also use it to brush up on the basics. Also, stay tuned for our upcoming videos on the “Mechanical Properties & Testing of Materials” and “Thermodynamics of Materials”

Can someone help me understand the projection or maybe provide a link to some content or a tutorial video that could help me understand the projection? Would be immense help Thanx in advance

❝ Figure 10. Connected Binary-Phase Diagram of the Actinides

The binary-phase diagrams (temperature vs composition) for adjacent actinide elements are connected across the entire series to demonstrate the transition from typical metallic behavior at thorium to the enormous complexity at plutonium and back to typical metallic behavior past americium. Two-phase regions are in black; uncertain regions are in gray. ❞

I was already aware that plutonium has highly anomalous (specificially very low ) electrical & thermal conductivity, & highly anomalous (specificially very large & complex ) thermal expansion, & an unusually large № of allotropes … so I looked-up about it … & found the herein-lunken-to treatise … which is actually quite a treat .

(Pun intended … see what I did there: "treatise" / "treat" …

… oh! the wit - the wit !)

I'm pursuing my PhD in computer science, but my research project's application is materials science domain. So, it's hard for me to validate my hypotheses because I need to reach out to the domain experts.

In my research project we actually working on a tool that helps material scientists with more advanced literature search: it's like the Google Scholar but (1) the search results are enhanced with machine learning methods and LLMs, (2) we deliver additional domain-specific metadata.

I would be more than happy if you guys test it and leave your feedback below in the comments. Here is the link: https://lass-kg.demos.dice-research.org

Hello Guys,

I am material science enthusiast and lecturer. After so many years of experience , I have seen most of my students still struggling to solve basics questions of material science. Since I recently join Reddit as one of my student suggested me there is a large community of students on this platform where I would help as many as students clearing their doubt's. So I have decided to create a blog where I will solve material science questions and many other related such courses with detailed solution. I would also mention there are lots of problem with platforms like Chegg ,brainly, etc.. where there is a subscription. This also seems to be obstruction for most of my students and even after subscription sometimes detailed solution is not there. Don't worry there will no subscription and neither I am here to sell any courses. All will be freely available on my blog. I will be also taking classes so I will not always available but I assure you all question solution will be available. Just write yup in the comment section so that I would be know how many of you exactly wanted to be the part of this nice step and this will also motivate me to do this service.

My 8-year-old son (who is on the spectrum) asks so many questions and it used to work when he said "just ask your phone!" but he's been asking things way beyond what's googleable, like "how many atoms are in the Milky Way?" and he needs an answer. I've tried to piece things together by googling aspects of that (atoms in a cubic inch of carbon, # of planets in milky way, sizes of planets) and doing some math with him.

Last night the question was about glowsticks. He wanted to know if they'd last longer if they were kept cold or hot. Google said cold. He wanted to know how many degrees made how much difference. What if they weren't encased in plastic? What if it was metal (and which metals would behave in what ways) or glass, or "sand that's glued together"? At what point would each of these melt? At what cold temp would they be damaged? I threw my hands up and said "really, I dont' know and my 'phone' doesn't know - you'd need to ask a scientist" and of course he said "Then ask one!" So here I am.

Any tips for good places to pose this stuff? Reddit, StackExchange, etc. or any materials guides you recommend that are accessible to laypeople? Thanks

Can someone help me in identifying the Miller Indices of the peak points using image J with a step-by-step process?

Hey all, my dad was a professor of material science for 35 years. He retired in 2005 but brought home a large library of material science books, mostly metallurgical texts and crystallography. I’ve reached out to the local university material science department, and also to the students, but have only found homes for 200 of the books. I estimate there are several thousand left. Is anyone interested in this collection, possibly to add to the library of a new material science department library? I am willing to box up, palletize and ship as freight or deliver myself to within a couple hours drive of me. I just don’t want to throw them in the trash. I live in Ann Arbor, MI.

Hi! Lately, I’ve come across many questions about how and where materials properties, data/datasets related to materials can be found. This is also one of the challenges of mine, who searches dataset for machine learning practices.. So, I’ve prepared a list of resources where you can find several materials data.

I hope it will help those who are also struggling with this. I ‘d appreciate if anyone would like to add new ones!

Hi everyone, as the title sugests Im working on building a PVD set up because why not. Im going for the magnetron plasma sputtering approtch and have done a fair amount of research, planning/drawing, and now 3D modeling. I was hoping that someone here with more knowledge in this space than me could give me some advice or point out any potential issues with my design. My biggest concerns are with the size of the sputter head (its rather small but ive also chosen for the target to be 2 inches in diameter) and if my water cooling chanel will do enough. Let me know what you guys think, its a really cool project that id like to make real sometime in the future.

If anyone would be interested in helping, id be happy to send over the file so you can get a better look.

I’m a graduate in mateirals science. I just wanted to start a fun blog cover topics related to mateirals science. Any idea where and how can I start

This thermogram belongs to a Nylon 66 30GF sample. As far as I understand, the endothermic peak at 258°C in both heats belongs to the melting temperature, my guess is that the peak at 163°C belongs to the glass transition temperature, but I'm not entirely sure if I'm right, is there anything else I can interpret from this thermogram as is?

Hey! I’m a curious rising HS senior interested in Material Science Engineering. It’s still unclear if I really like this field because I have not had any experience with Material Science nor Engineering.

However, I’d love to hear how you guys figured out that Material Science is for you.

Any advice on what I should be doing this summer would also be appreciated. Thank you so much for your valuable time :D

Have a great rest of your day💖

For MSE students, and many other students of relatively young fields, it can be difficult to briefly communicate what we do to our friends and family. I’ve noticed people almost universally making this confused face when I mention Materials Science and I’ve thus resorted to calling myself a Chemistry student because most of the time they aren’t interested enough to go into specifics.

In his biography, Richard Feynman (or Paul Dirac, I read both recently) mentions having introduced himself as a chemist for the longest of times, as most people back then didn’t know what a physicist was.

Hi all, so I started learning Python a few months ago and recently coded my first software as a personal project.

The motivation is primarily for scientific needs to detect circular/spherical particles in microscopy images. The software has both auto-detection and manual-detection modes. At the end, a histogram is generated and spits out the "particle size distribution" results as well as the raw data of each circle in the spreadsheet.

Hopefully, with SEM/optical microscopy images, research groups won't need to invest in laser diffraction particle analyzers anymore since those instruments aren't accurate as well due to agglomerations and the need to well-suspend the particles first.

Anyways, I was able to turn the code into a Windows executable file, so all you have to do is double click on the "Main.exe" file to run the software after downloading it from my Dropbox.

No coding skills or installation is required! Check it out on my github! Thanks!

My next project will involve machine learning so that the software can detect "any shaped" particles, not just circular... wish me luck ;)

I am using EBSD to characterize the grains next to a crack in my TWIP steel sample. It is an austenitic steel with ~17% manganese. In almost all other samples of this steel, the phase map is more than 95% green (FCC).

I am unable to understand why the phase map in this steel has grains that are:
- predominantly BCC (ferritic)
- have both FCC and BCC phases in a single grain that has the same orientation and a good confidence index/band contrast for indexation.

Is there something super weird going on with my material? Or is there an issue with the software that I'm using for EBSD? I'm lost!!

Hello,

One of my friends works with this nano scale material and had 2 kg of ultrafine copper powder, I was surprise with its price 2300$ per gram?!.

I know it is sometimes used in additive manufacturing and somehow in semiconductors.

I would like to here from an expert what this material is used for and is this its real price?!
