This review considers the compositions, the main process routes, microstructure and
structural properties of microalloyed steels. The background and brief history are followed by …

A pragmatic shift has been ongoing for the metal development of industrialization for the last
several decades. In various engineering and industrial applications, there is a high demand …

The effect of isothermal transformation temperatures on wear performances of a newly
designed high-silicon carbide-free bainitic steel was studied. Wear tests were performed by …

We develop a new ultrastrong medium Mn steel with a density reduced to 7.39 g cm–3. It
has a novel tri-phase microstructure comprising a hierarchical martensitic matrix (α') …

Low temperature bainite is a mixture of ferrite and austenite with a high dislocation density
and nanoscale precipitates produced by isothermal transformation of the austenite in high …

Strength and toughness are a couple of paradox as similar as strength-ductility trade-off in
homogenous materials, body-centered-cubic steels in particular. Here we report a simple …

It is crucial to eliminate the thermally and mechanically less stable austenite blocks as much
as possible if enhanced mechanical properties are demanded in high performance …

The effect of multi-step austempering treatments on the microstructure and mechanical
properties of a novel medium carbon high silicon carbide-free bainitic steel was studied …

A low-carbon Mn-Si-Cr-Mo alloyed steel was treated by two different heat treatment routes,
namely bainite-based quenching plus tempering (BQ-T) and bainite-based quenching …

The volume fraction and morphology of the microstructural constituents are extremely
important when discussing the impact toughness of nanostructured bainitic steels. On the …
