Nickel-based super alloys are gaining more significance, now-a-days, with extensive
applications in aerospace, marine, nuclear reactor and chemical industries. Several …

Presently, the service performance of new-generation high-tech equipment is directly
affected by the manufacturing quality of complex thin-walled components. A high-efficiency …

Gas turbine components are often shot-peened to improve surface integrity and fatigue
capability. Compressive Residual Stress (CRS) and increased surface hardness are the key …

Critical aero-engine components such as turbine discs must withstand severe cyclic
stresses, which can eventually lead to low cycle fatigue (LCF) failures. These components …

The main purpose of this study is to investigate the mechanical properties and micro-
structures of IN718 super-alloy subjected to Cryogenic Treatment (CT). Tensile tests were …

Elastic strain and residual stress values in an engineering material were determined by high-
resolution EBSD (HR-EBSD) using reference patterns from annealed, recrystallized …

In this study, a continuum damage mechanics based method is proposed to calculate the
fatigue life of a specimen with an impact pit. The impact process is simulated by a quasi …

Residual stresses, RSs, both at the macroscopic and microscopic scales, are developed
during component manufacture. Knowing the magnitude of these stresses is crucial in …

We have assessed the elasto-plastic (sub) surface behaviour of 7050-T7451 aluminium
alloy treated by shot peening using S110 steel shots of 300 μm in diameter and two different …

The residual stress generated in a superalloy during heat treatment affects the subsequent
processing of the workpiece and may even adversely affect its performance. This paper …
