As a representative of steels available in the market, medium-Mn steel shows vast
application prospects in lightweight automobile fields. This review details the research …

We applied a hot rolling direct quenching and partitioning (HDQ&P) process to a low-C low-
Si Al-added steel and obtained a Q&P steel containing 40 vol% of ferrite. Microstructure …

We performed ultra-fast heating (150° C/s) quenching and partitioning (Q&P) processes to a
cold-rolled low-carbon low-alloy steel. Adjusting the annealing temperature, we obtained …

Advanced high strength steels for the auto industry are in high demand regarding the
development of new type of steels, reliable and economic welding techniques, etc. In this …

The paper proposed a machine learning model for multiclass classification of quenched and
partitioned (Q&P) steel microstructure type. In this work, we implemented the k-nearest …

Intermetallic compounds (IMCs) play an important role in the welding quality of steel and
aluminum (Al) alloys by friction stir welding (FSW). However, the evolution mechanism of …

Improving strength may lightweight car bodies by thinning the structure gauge while bearing
the same crash loads. Development of the third generation advanced high-strength steels …

The QP980-DP980 dissimilar steel joints were fabricated by fiber laser welding. The weld
zone (WZ) was fully martensitic structure, and heat-affected zone (HAZ) contained newly …

A novel ultra-high strength transformation-induced plasticity (TRIP) steels with submicron-
size martensite/austenite (M/A) constituents was processed by non-isothermal annealing …

Rebar is the most important material in large-scale engineering structures, and its fine
structure determines the strength and seismic resistance of rebar. The objective of this study …
