M50 bearing steel, as the important material used in aeroengine bearing, exhibits low cold
working capacity with high susceptibility to produce voids. This would lead to the …

This study aims to investigate the influence of rare earth (RE) addition on the friction and
wear behavior of M50 bearing steel. The results show that RE addition has little effect on …

The application of high-strength Al–Zn–Mg–Cu alloy is seriously limited because of its poor
ductility and fatigue property. In this work, an electroshock treatment (EST), which is an …

Laser shock peening is widely used in mechanical property improvements of metallic
materials. One concerning factor is the nonuniformity of mechanical properties and …

The evolution of microstructure and mechanical properties during tempering of M50 steel
with bainite/martensite (B/M) duplex structure have been investigated. The microstructural …

The residual stress and mechanical anisotropy caused by cold rolling (CR) seriously
deteriorate the heat treatment distortion and final service performance of M50 steel. In this …

The tempering response and mechanical properties of the austempered Cr4Mo4V steel with
bainite/martensite multiphase structure were investigated. During the tempering, the …

This article reports that the uniformity of the alloy steel 20Cr2Ni4A is improved by using
pulsed magnetic treatment. The pulsed magnetic field with 1, 4 and 9T was applied on the …

The influence of different cryogenic sequences on the rolling contact fatigue (RCF) life of
M50-bearing steel has been studied. The results show that direct cryogenic treatment after …

M50 steel is a commonly used material for aeroengine main shaft bearings. In this study, a
gradient nanostructured M50 steel was fabricated by an efficient surface nanocrystallization …
