摘要：
The austenitic stability of selective laser melted austenitic stainless steel was investigated by the tensile tests in the 80-300 K temperature range. The selective laser melting process greatly improved the yield strength, but severely suppressed the stain-induced alpha' martensitic transformation compared with the conventional austenitic stainless steel. The high density of low-angle grain boundaries and fine cellular microstructures were observed in the selective laser melted austenitic stainless steel, which suppressed dislocation slip and deformation twinning during deformation, resulting in the reduction in the nucleation sites of a' martensite and the enhancement of the austenitic stability.
