Tóm tắt: | Characterisation of macrostructure, microstructure and precipitate distribution of 2024-T351 aluminium
Friction Stir Welding (FSW) joints has been conducted in order to characterise the critical areas for natural
fatigue crack initiation. Inhomogenous micro parameters that governing the non-uniform microstructure sizes
and precipitates distribution. The cyclic strength of the weld micro-regimes are controlled by grain size and
distribution of precipitates achieved during the weld process. The comprehensive information of micro and
macro mechanic gathered will be used to assist in understanding the mechanism that governed the fatigue crack
initiation, propagation and life of this weld |
