Delayed deformation-induced martensite transformation and enhanced cryogenic tensile properties in laser additive manufactured 316L austenitic stainless steel

Additive Manufacturing, 2021
The cellular dislocation structure is an important microstructure aspect in fusion-based laser metal additive manufactured (MAM) parts. Its role in increasing strength and ductility at room temperature (298 K) is a known phenomenon. In this work, we have

The dominating role of austenite stability and martensite transformation mechanism on the toughness and ductile-to-brittle-transition temperature of a quenched and partitioned steel

Materials Science & Engineering: A, 2021
The effect of austenite stability and martensite transformation (MT) mechanism on the tensile and impact properties has been investigated for Fe-0.3C-2.7Mn-1.7Si (wt.%) quenched and partitioned (Q&P) steel. The stability of metastable retained austenite (

Crystallographic texture evolution and martensite transformation in the strain hardening process of a ferrite-based low density steel

Journal of Materials Science & Technology, 2021
The strain-induced martensite transformation is of great importance in the strain hardening process of ferrite based low-density steel. Based on the microstructure analysis, the texture evolution and martensite transformation behavior in the strain ...
