We develop a new ultrastrong medium Mn steel with a density reduced to 7.39 g cm–3. It
has a novel tri-phase microstructure comprising a hierarchical martensitic matrix (α') …

Tuning thermal treatment schedule has been confirmed as an effective technical route for
achieving optimum properties of steels. In the present work, the role of a unique duplex …

Ferrium S53 is a new secondary-hardening ultra-high-strength stainless steel, with more Cr
than other Co-Ni ultra-high-strength steels. Austenite has a great effect on the fracture …

The effect of welding heat input characterized by the cooling time taken from 800° C to 500°
C (t 8/5) on the microstructural evolution, V (C, N) precipitation and resultant mechanical …

Square and circular tubes were tested experimentally and numerically in quasi-static three-
point bending. A finite element model with failure criterion was developed that correlated …

In this article, an effort has been made to investigate the evolution of microstructure, texture
and mechanical properties of AA 7075 alloy during equal channel angular pressing (ECAP) …

Abstract Development of new ultrahigh strength steels with high strength and high
toughness requires thorough comprehension of nanoscale precipitation mechanisms. In this …

Abstract In this study, 15–5 precipitation hardening (PH) martensitic steel powder was
successfully deposited on U75V eutectoid pearlitic steel to form structurally graded material …

Ultra-low carbon Ti containing bainite steel was prepared by multipoint dispersion supplying
Ti wire in the melt, followed by controlled rolling, relaxation, direct-quenching (DQ), and …

This article presents a comprehensive evaluation of a new residual stress reduction method
based on magnetic-vibration stress relief treatment for cold-rolled DP590 high-strength steel …
