The Role of Slip System Activation on Ni-Based Superalloy High Temperature Fatigue
… These materials are desirable due to their high strength, resistance to creep, corrosive environment, and high temperature. It has been well documented that material fatigue is characterized by material microstructure, type of loading, and other parameters. Currently, research into the …

Thermo-elastic-plastic analysis for elastic component under high temperature fatigue crack growth rate.
… presents a fundamental understanding of the fatigue crack growth mechanisms of AISI 420 martensitic stainless steel, based on the comparison analysis between the theoretical and numerical modelling, incorporating research findings under isothermal fatigue loading for solid cylindrical …

High temperature fatigue and creep deformation behavior under static and cyclic loading in ceramics containing a viscous grain boundary phase
Fatigue and creep deformation behavior of a commercial grade of alumina with 6 wt % of grain boundary viscous phase was investigated. Two failure mechanisms were observed at 1000 C under static loading. At high stresses, fracture was dictated by slow growth of a single dominant flaw along the grain …

High temperature fracture toughness and fatigue behavior of ti-zr-mo and w-re alloys for x-ray tube application
… (W-Re) alloy. The target must endure extremely high temperature, associated with high thermal stress, and mechanical stress due to the centrifugal force induced by high speed rotation of the target. Therefore, studies on high temperature fracture and fatigue behavior of these materials would be …

Investigation of thermal effects on fatigue crack closure using multiscale digital image correlation experiments
… multiple length scales, the thermal effects on fatigue crack closure of Hastelloy X, a nickel-based superalloy. Using multiscale, digital image correlation (DIC), macroscale experiments were performed at 2x magnification (2 µm/pix), providing full-field crack closure measurements. Microscale …
