Abstract:
ABSTRACT
Mechanical surface treatments such as deep rolling or laser-shock peening can markedly affect the cyclic performance of light-weight alloys, especially if significantly
thick work hardened surface regions are induced. At room temperature, the cyclic deformation behaviour is strongly influenced by the nature of the induced near-surface
microstructures provided that they remain stable during fatigue loading. At elevated temperatures, the stability of near-surface work hardening and local microstructures
plays an even more important role since the process-induced residual compressive stresses are likely to anneal out partially or completely. This overview illustrates to what
extent deep rolling can affect the cyclic performance of various light alloys being fatigue loaded in stress control at ambient and elevated temperatures.
