@wesbos @khhbenny101 @johnsonstickk Annealed SUS304 is almost nonmagnetic. But machining (knurling) induced cold work can cause phase transformation from non-mag austenite to a ferromagnetic phase. To be honest, the main cost here is machining labor. Faking commodity materials like SUS does not save much.

@khhbenny101 @johnsonstickk It’s 304 stainless - I just checked. I’m actually very knowledgeable about stainless - it’s a passion. Life’s working out great for me benny, thanks for asking!

China is nuts. You can just DM a machinist and they will make you custom stainless barbell grips without ever speaking a word of English. $20 a pair

Okay, time for a DFM roast so all you engineers can see how machinists think. @emm0sh volunteered this part, I don't have the time to do a full write up so I'm just gonna live tweet me going through it, exposing the sins, and optimizing it (1 of ?)

Almost a perfect single crystal!

Reserved one for myself😉 #recrystalisation

To celebrate the holiday season, I’ve recreated the iconic Atomix crystallography toy, originally designed by François Dallegret in 1966! Probably the best toy for materials scientists. Check out the link for more details. wp.me/p4Vqq1-pe

Now comes a new #JDM design!

These car rego plates need to be reserved for true electron microscopists! #fridgemagnets

@jwt0625 Last time I saw this book, it was still in green color.

This is the content I’m here for😂

@ColinOphus Congratulations, Colin!

We couldn't agree more! Great to see the achievements of Prof. Joanne Etheridge recognised, and importantly, recognition of the significant impact electron microscopy has in understanding materials @micro_au @Monash_MTRP

Absolutely phenomenal! Although I'm no longer an active gamer, and my 10+ yr old pc could hardly handle the graphics, I placed the order on steam so perhaps some time later I could revisit my childhood memories once I built a new system.

@jwt0625 It's the caustics of my DIY LED bar through a cheap magnify glass. Used to be pretty happy with it until I saw all the aberrations in it...

@IMBalENce What am I looking at?

Microscopist attempt to live with daily aberrations ...

Holy shit! This is an absolute world first! An 8 bit processor formed on a glass substrate as a continuous grain! This is genuinely amazing! This is literally the next generation of integrated circuits being developed!

Interesting interference pattern of two fridge magnets.

@RichBean0 I super glue the Si wafer to the specimen, so pretty robust. The ECP I got from Zeiss sigma is around 3-4deg range at the lowest mag at 20kV. Perhaps the ECP you have also works but would be better to try higher voltage with narrower band and wider range?

Super excited to announce the official release of openECCI, our very first open source Python library for Electron Channelling Contrast Imaging (ECCI) analysis of crystal defects in Scanning Electron Microscope (SEM). Check our Github page for more info github.com/IMBalENce/open…

@RichBean0 I'm currently compiling a tutorial paper explaining the details, hopefully will be on arxiv very soon. Will keep you updated.
