Towards interrelationship of grain size, cell parameters and flow stress in type 316L stainless steel
TLDR
In this paper, the interrelationship between grain size, cell size, and cell wall thickness and flow stress in 316L stainless steel was investigated, and it was found that smaller cell interior sizes and thicker cell walls result in a greater contribution of grain interior to strengthening of polycrystalline material than the grain boundaries.About:
