Journal ArticleDOI

Evolution of subsurface plastic zone due to rolling contact fatigue of M-50 NiL case hardened bearing steel

TL;DR: In this article, a microindentation technique was used to measure the changes in the material hardening and softening characteristics within the RCF affected zone and represent the change in the form of microhardness maps.
Journal ArticleDOI

On the strain rate sensitivity of plastic flow in metallic glasses

TL;DR: In this paper, the nanoindentation technique was employed to examine the strain rate sensitivity, m, and its dependence on the structural state of a Zr-based bulk metallic glass (BMG).
Journal ArticleDOI

On the evolution of stresses due to lattice misfit at a Ni-superalloy and YSZ interface

TL;DR: In this paper, the authors used the principle of elastic strain energy minimization to predict the possible ranges of allowable lattice misfit for the formation of coherent and semi-coherent interfaces between a Ni superalloy substrate and a cubic yttria stabilized zirconia (c-YSZ) ceramic coating.
Journal ArticleDOI

Residual stresses in functionally graded thermal barrier coatings

TL;DR: In this article, an analytical methodology based on the bending of plates has been used to model the residual stress distribution through the layers of a functionally graded (FG) cermet top coat-bond layer-substrate system after cooling from a high deposition temperature.
Journal ArticleDOI

Cyclic Constitutive Response and Effective S–N Diagram of M50 NiL Case-Hardened Bearing Steel Subjected to Rolling Contact Fatigue

TL;DR: In this article, a combined experimental and numerical method is developed to estimate the continuously evolving cyclic plastic strain amplitudes in plastically deformed subsurface regions of a case-hardened M50 NiL steel rod subjected to rolling contact fatigue (RCF) over several hundred million cycles.
