Grain size effects in micro-tensile testing of austenitic stainless steel
A micro-tensile test system is under development at the National Institute for Standards and Technology (NIST) and is based on tensile test techniques developed for thin films, but it provides the capability of testing samples from bulk material. Example specimen dimensions are a gage section length of 342 microns, width of 75 microns, and thickness of 80 microns. The micron size scale of the specimens presents the potential to analyze local deformation of a material within a specific region of the microstructure. The micro-tensile system could also be useful in material modeling, because samples ...
