Ultra-high strength steels are the crucial irreplaceable materials in the fields of aerospace,
national defense and military industries. Unfortunately, it is challenging to achieve the …

A novel strategy through controlling the selection of martensitic variant in metallic materials
is proposed to break through the trade-off between strength and ductility. Here we prepared …

We studied the initial microstructures, mechanical responses and deformation-induced
microstructures of the medium-Al Fe-21Mn-6Al-1C-xSi (x= 0, 1.5, 3 wt.%) lightweight steels …

Advanced high-strength steels are key structural materials for the development of next-
generation energy-efficient and environmentally friendly vehicles. Medium Mn steel, as one …

Abstract Effect of electric current on precipitation hardening for advanced high-strength steel
is investigated based on mechanical testing and microscopic observation. Complex-phase …

In this work, an attempt was made to develop NiAl precipitation-strengthened HSLA steels
by introducing Al to the alloy composition of conventional HSLA steels. A novel HSLA steel …

Static force, ultrasonic amplitude, feed rate, and rolling spacing parameters of 42CrMo steel
treated by the ultrasonic surface rolling process (USRP) were optimized by the Grey-Taguchi …

Abstract 9Cr-F/M− xSi (x= 0–1.0 wt%) steels were fabricated through vacuum induction
melting technique and processed by hot forging, hot rolling, normalizing and tempering …

Medium Mn steels are promising candidates for the third-generation advanced high-strength
steels due to their good combination of ultimate tensile strength (UTS) and total elongation …

Dislocation affects the thermal conductivity and coefficient of the thermal expansion of high-
volume fraction SiC p/Al composites. However, it still remains unclear to what extent the …
