The refinement of ferrite grain size is the most generally accepted approach to
simultaneously improve the strength and toughness in steels. Historically, the level of ferrite …

Ultrafine grained (UFG) steels with grain sizes around 1 micron exhibit an excellent strength‐
ductility combination and have been extensively studied worldwide. Among the different …

Rebar is the most important material in large-scale engineering structures, and its fine
structure determines the strength and seismic resistance of rebar. The objective of this study …

The post-dynamic transformation that takes place during the subsequent isothermal holding
for the case when dynamic strain-induced transformation (DSIT) from austenite to ferrite …

Dynamic recrystallization (DRX) is an important grain refinement mechanism to fabricate
steels with high strength and high ductility (toughness). The conventional DRX mechanism …

A modified cellular automaton modeling has been performed to investigate the dynamic
strain-induced transformation (DSIT) from austenite (γ) to ferrite (α) in a low carbon steel. In …

Grain refinement is one of the effective methods to develop new generation low carbon
microalloyed steels possessing excellent combination of mechanical properties. In the …

A novel approach was used to produce an ultrafine grain structure in low carbon steels with
a wide range of hardenability. This included warm deformation of supercooled austenite …

Laboratory thermomechanical processing (TMP) using single pass hot compression
experiments on a low carbon Nb–Ti microalloyed steel have been carried out to study the …

Warm torsion testing was carried out on a low carbon Nb-microalloyed steel to study the
mechanism of ferrite grain refinement during warm deformation. Deformation characteristics …
