摘要：
The interaction between deformation-induced martensite and voids has been quantitatively established during the tensile deformation of metastable austenitic stainless steel at various strain rates under ambient temperature where the initial inclusion volume fraction was kept constant. The inhomogeneous distribution of deformation-induced martensite under tension influences void nucleation and growth, and hence keeps imprint on dimple geometries on fracture surfaces.
