Aerospace is a key market driver for the advancement of additive manufacturing (AM) due to
the huge demands in high-mix low-volume production of high-value parts, integrated …

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 …

This is a viewpoint paper on recent progress in the understanding of the microstructure–
property relations of advanced high-strength steels (AHSS). These alloys constitute a class …

The conventional role played by precipitates in crystalline solids is in blocking the motion of
dislocations and for consequentially hardening, a mechanism attributed to Orowan's finding …

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 …

In this paper, maraging steel powder was deposited on top of an H13 tool steel using laser
powder bed fusion (LPBF) technique. The mechanical properties, microstructure, and …

Control of discontinuous and continuous precipitation is crucial for tailoring the
microstructure and mechanical properties of NiAl-strengthened steels. Through a …

The microstructure evolution and tensile properties of a newly designed Fe-21Mn-10Al-1C-
5Ni (wt.%) lightweight steel subjected to two annealing conditions (inducing partial …

The synergistic effects of Mo, Ti, and Cr on nanoscale precipitation and mechanical
properties of maraging stainless steels were systematically studied using high-resolution …

Traditionally, precipitates in a material are thought to serve as obstacles to dislocation glide
and cause hardening of the material. This conventional wisdom, however, fails to explain …
