DOI: 10.1016/j.mtcomm.2019.100646
Abstract: Abstract An ultrahigh-strength steel with sufficient uniform elongation (UE) and high strain-hardening ability was fabricated by a combination method of heavy warm rolling (HWR) on the metastable austenite and subsequent quenching (Q). The WR-Qed steel… read more here.

DOI: 10.1080/09500839.2021.1936258
Abstract: ABSTRACT In general, the formation of martensite in the metastable austenite grains in steels during nanoindentation investigations is believed to be induced by strain as the plastic deformation of austenite takes place prior to the… read more here.

DOI: 10.1134/s1063784217040089
Abstract: We have analyzed the effect of elastoplastic cyclic straining on anisotropy of elastic properties of 08Kh18N10T metastable austenite steel. The possibility of determining the strain amplitude of the fatigue loading cycle by an acoustic method… read more here.
