Ultrafine grained steels with grain sizes below about 1μm offer the prospect of high strength
and high toughness with traditional steel compositions. These materials are currently the …

The potential of the concept of phase reversion process to obtain nanograined (NG)
structure with high strength–high ductility combination and to fundamentally understand the …

Abstract In an Fe–9 at.% Mn maraging alloy annealed at 450° C reversed allotriomorphic
austenite nanolayers appear on former Mn decorated lath martensite boundaries. The …

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 …

The mechanical properties of an ultrafine grained 0.2% C–Mn steel, processed by large
strain warm deformation and subsequent annealing, have been investigated. The …

The evolution of microstructure and texture of a 0.2% C–Mn steel during large strain warm
deformation and subsequent annealing has been investigated. The process of grain …

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