This work investigated the evolution of multiphase microstructure and impact fracture
behavior of medium carbon high silicon high strength steel subjected to the austempering …

Abstract 50CrMnSiVNb spring steel was quenched at 760, 820, 880, 940 and 990° C to
obtain different microstructures and nucleation rates of tempered carbides. The results show …

Tensile/impact behaviour of lower bainite obtained in high-Si steel 55Si3Mn2CrMoVNb was
studied using SEM, TEM, and XRD. Specimens were austenitized at 900◦ C and …

In this research, a new type of spring steel with ultra-high strength and toughness was
designed, and its mechanical properties and microstructure under different heat treatment …

This article explores the characteristic flow behaviour and microstructure analysis of Si–Cr
spring steel under various compression conditions by a Gleeble 3500 facility. To better …

The present work aimed at studying the effect of the two-step “Quenching-and-
Partitioning”(QP) processing with a prolonged partitioning stage on the mechanical …

Certain inclusions in high-strength 60Si2Mn-Cr spring steel result in poor resistance to
localized corrosion. In this work, to study the effect of inclusions on the localized corrosion …

A new formula is introduced to analytically determine the critical torsional load or angle of
rotation that confers instability in a tension spring under combined tension and torsion load …

The present study explores the application of single‐step quenching and partitioning (QP)
treatments to low‐silicon commercial AISI 4140 steel. Fractions between 4.6% and 7.8% of …

The novel cast irons of chemical composition (wt%) 0.7 C—5W—5Mo—5V—10Cr—2.5 Ti
were invented with the additions of 1.6 wt% B and 2.7 wt% B. The aim of this work was to …
