TL;DR: In this paper, a series of dual-phase (DP) steels containing finely dispersed martensite with different volume fractions of martensites (Vm) were produced by intermediate quenching of a boron- and vanadium-containing microalloyed steel.

TL;DR: In this article, a series of ferrite-bainite dual-phase (FBDP) steels containing wide variation of the harder constituents have been prepared from a low carbon Nb-micro-alloyed base material by suitable heat treatments.

TL;DR: In this paper, microstructure, hardness and wear behavior of AISI D2 steel subjected to varied sub-zero treatments have been examined with reference to conventional heat treatment, and the obtained results infer that retained austenite content is reduced by cold treatment, but is almost completely eliminated by both shallow and deep cryogenic treatments.

TL;DR: In this paper, a series of wear tests has been carried out on AISI D2 steel samples subjected to cryotreatment at 77 K for different durations, and the wear rates at different loads and sliding velocities, morphologies of the worn-out surfaces and the characteristics of the wear debris have been systematically examined to assess the possible critical duration of Cryotreatment to achieve the best wear resistance property.

TL;DR: In this paper, the influence of deep cryogenic processing in between quenching and tempering (QCT) on the carbide precipitation and the tribological behavior of a commercial AISI D2 steel has been examined.
