“…Time-dependent deformation and fracture of multi-material systems at high temperature was presented by Xuan et al [13] for a FGM thick-walled sphere subjected to an internal pressure. Loghman et al [14] studied the magnetothermoelastic creep analysis of FGM cylinders and found that radial stress redistributions are insignificant compared with the circumferential and effective stresses with regards to material in-homogeneity.…”

This article compares the creep testing behavior of AISI 4340 high-strength steel in the as-received and coated conditions. The coating material used is a NiCrBSi self-fluxing alloy. The microstructural characterization was carried out using optical and scanning electron microscopy. The creep tests were conducted at a temperature of 550 °C and with loads of 200, 250, and 300 MPa. The microstructure analysis of the deposited layer reveals some inclusions, very little porosity, and good adhesion to the substrate. The results of the creep tests indicated a decrease in the time to rupture under loads of 250 and 300 MPa for the coated steel. At a load of 200 MPa, the coated steel presents longer times to rupture and higher yield strength, demonstrating an improvement over the uncoated steel under these test condition. Fracture surface inspection showed a failure by a ductile fracture in both samples, with and without coating.

“…The presence of anisotropy leads to significant reduction in the tangential and radial strain rates over the entire disc and helps in restraining creep response both in the tangential and in the radial directions. Xuan et al 15 have studied the time-dependent deformation and fracture performance of multimaterial system and structures at elevated temperature. He developed a microregion deformation measuring technique which allows the direct measurement of the full creep strain fields of multimaterial system at higher temperature.…”

Steady-state creep response in a rotating disc made of Al-SiC (particle) composite having linearly varying thickness has been carried out using isotropic/anisotropic Hoffman yield criterion and results are compared with those using von Mises yield criterion/Hill's criterion ignoring difference in yield stresses. The steady-state creep behavior has been described by Sherby's creep law. The material parameters characterizing difference in yield stresses have been used from the available experimental results in literature. Stress and strain rate distributions developed due to rotation have been calculated. It is concluded that the stress and strain distributions got affected from the thermal residual stress in an isotropic/anisotropic rotating disc, although the effect of residual stress on creep behavior in an anisotropic rotating disc is observed to be lower than those observed in an isotropic disc. Thus, the presence of residual stress in composite rotating disc with varying thickness needs attention for designing a disc.
