Lightweight sheet metals are attractive for aerospace and automotive applications due to
their exceptional properties, such as low density and high strength. Sheet metal forming …

Abstracts High-strength steels support the rapid development of modern automobile
industry. Especially quenching-partitioning (QP) steels have presented the considerable …

In this study, the ductile fracture of the alloy metal is analyzed. First, the key factors affecting
the initiation of ductile fracture are investigated. Then, a new uncoupled ductile fracture …

A heterostructured medium Mn steel with duplex phases (ferrite and austenite) and multiple
morphologies (lath-typed and granular) is fabricated by a novel two-stage warm rolling …

Quenching and partitioning (Q&P) steels possess high strength and good ductility because
of the transformation of metastable austenite to martensite, which is referred to …

This study develops a novel crystal plasticity (CP) model incorporating deformation-induced
martensitic transformation (DIMT) and transformation-induced plasticity (TRIP) effect to …

A non-associated flow rule (non-AFR) constitutive model is proposed to describe the
evolving yield stress and plastic potential surfaces of sheet metal under plane stress …

Undesirable fracture resistance has led to critical safety concerns in ultra-high strength
quenching and partitioning (Q&P) steels. The present work proposes a new heat treatment …

Renowned for the superior mechanical properties and adeptness at cold-forming,
Quenching and Partitioning (QP) steels have gained prominence as a promising candidate …

Restrained by the strength-ductility tradeoff, it is still challenging to develop advanced high-
strength low carbon low alloy (LCLA) steels with superior strength-ductility combinations and …
