The study of heterostructured materials (HSMs) answered one of the most pressing
questions in the metallurgical field:“is it possible to greatly increase both the strength and the …

Severe plastic deformation (SPD) techniques such as laser shock peening (LSP) have been
widely adopted to modify microstructure of materials. Understanding the plastic deformation …

Steels with sub-micrometre grain sizes usually possess high toughness and strength, which
makes them promising for lightweighting technologies and energy-saving strategies. So far …

Three ferrite/martensite dual-phase steels varying in the ferrite grain size (12.4, 2.4 and 1.2
μm) but with the same martensite content (∼ 30vol.%) were produced by large-strain warm …

A low-alloy and high-carbon martensite steel (0.66% C) with ultrafine grains is produced by
combination of Tempforming (tempering and deforming of a quenched steel) and reheating …

Materials are typically ductile at higher temperatures and become brittle at lower
temperatures. In contrast to the typical ductile-to-brittle transition behavior of body-centered …

Our strategy is to enhance the fracture property of ultra-high-strength low-alloy steels with a
yield strength of 1.4 GPa or over by arresting the propagation of brittle cracks in hierarchical …

Ultrafine grained steels show little room temperature tensile ductility compared with coarse
grained samples of the same compositions. In order to increase the ductility, the work …

Bulk ultrafine-grained (UFG) low-carbon steel bars were produced by caliber rolling, and the
impact and tensile properties were investigated. Initial samples with two different …

Tensile behavior and structure-property relationship of ferritic steels with nano-sized carbide
dispersion were invesigated using Ti-added steel and Ti, Mo-added low carbon steels. By …
