Abstract: Abstract We investigated the effects of solute carbon concentration on the mechanical properties of Fe–19Cr–8Ni–0.05C and Fe–19Cr–8Ni–0.14C metastable austenitic steels. These steels showed an FCC(γ) → HCP(ε) → BCC(α′) martensitic transformation, resulting in transformation-induced plasticity (TRIP). The presence of… read more here.

Abstract: Cryogenic turning of metastable austenitic steels allows for a surface layer hardening integrated into the machining process, which renders a separate hardening process obsolete. This surface layer hardening is the result of a superposition of… read more here.

Abstract: Abstract Microstructure-sensitive fatigue crack growth in 304 metastable austenitic stainless steel containing nanotwin bundles was studied using a miniature compact tension specimen combined with post-fatigue metallographic examinations. The single-variant nanotwinned specimens exhibited high crack growth… read more here.

DOI: 10.1038/s41598-024-65505-3
Abstract: Excellent strength–ductility balance in metastable Fe–Cr–Ni austenitic alloys stems from phase transformation from austenite (fcc structure) to αʹ martensite (bcc structure) during deformation, namely deformation-induced αʹ martensitic transformation (DIMT). Here, DIMT in a metastable Fe–17Cr–7Ni… read more here.

DOI: 10.1134/s0031918x20070066
Abstract: This work studies the structure and texture evolution in the 03Kh19N10 corrosion-resistant metastable austenitic steel (0.05C–18.2Cr–8.8Ni–1.65Mn–0.43Si–0.05P–0.04S wt %, and Fe for balance) during cold rolling, which results in twinning and martensitic transformation. The strain-induced martensite… read more here.
