-----Single crystal stainless steel
July 7, 2010
Hi,
Am a PhD student.
I have a polycrystalline 316L type stainless steel. Due to its polycrystalline nature I cannot create uniform nanofeatures. I was wondering is there any way to make single crystal stainless steel. If any one knows the answer will you please get back to me?
Thank you in advance!

I have not heard of it in SS, but it is done in titanium. Talk to the Rolls Royce unit in Scotland that builds the big jet engines. They should have a metallurgist that could point you in the right direction. I would have assumed that your major professor could have pointed you to an area where you could research this information.

Feroze,
I work in stainless steel now, but I did work in graduate school involving diffusion in tricrystals, which of course required us to create single crystals first to use in growing the tricrystals. We were using copper and a Bridgman Furnace.
From what I learned in class about the microstructures and element segregation produced during the cooling of alloys in castings, I strongly suspect that growing single crystals of alloys is much more difficult than with a single element. But I agree that you should consult with a metallurgist that deals more frequently in single crystals.
