Processes of severe plastic deformation (SPD) are defined as metal forming processes in
which a very large plastic strain is imposed on a bulk process in order to make an ultra-fine …

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

This article briefly summarizes the extensive information now available, from recent
experiments and theoretical models, addressing the enhanced tensile ductility of …

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 …

There is currently a gap in our understanding of mechanisms that contribute to high strength
and high plasticity in high strength UFG ferritic steel with nano-size Fe 3 C carbides in …

Stress–strain curves for ferrite-cementite (FC) steels with ferrite grain sizes between 0.47
and 13.6 μm were studied by tensile tests with strain rates of 103, 100, and 3.3× 10− 4s− 1 at …

An Fe–17Mn–0.6 C steel with ultrafine elongated grain structure was successfully produced
utilizing a multi-pass caliber-rolling process at 773K. The uniform elongation of the …

The microstructural evolution and mechanical properties were investigated using a caliber
rolled Mg–5Y-2.5 Zn (in at.%) alloy. Deformation kink bands could be induced by the caliber …

Although mechanical behaviors of ultrafine grained steel containing nanosized particles at
low strain rates was extensively studied, its mechanical performance at high strain rates was …

The influence of room temperature flat rolling on microstructure, mechanical properties, and
shape change in twinning-induced plasticity (TWIP) steel wire has been investigated to …
