Investigation into heat treatment and residual stress in laser clad AA7075 powder on AA7075 substrate

The laser cladding of AA7075 powder onto a AA7075 substrate was conducted to evaluate the effect of heat treatment and measure residual stress between the clad layer and substrate in order to better understand the effect of laser cladding. The microstructure formed in the clad region was characteristic of a high cooling rate, which is typical for laser cladding. The heat affected zone showed co...

ROLE OF SiCp ON THE SOLIDIFICATION RATE AND FORGEABILITY OF STIR CAST LM6/SiCp MMCs

The present paper aims to investigate the solidification behavior and the forgeability of Aluminum alloy (LM6)-SiCp composites at different section of three-stepped composite castings. The temperature of the cast composites during solidification has measured by putting K-type thermocouples at the center of the each step/section, from which the solidification curves were constructed. The forgeab...

Thermal Shock Properties of ZrB2-SiCp-Graphite and ZrB2-SiCp-AlN Ceramic Matrix Composite Material

Thermal shock property of the material can be improved by improving fracture property of the material. In this paper, factors affecting fracture property have been studied and the effect of residual stress, microstructure, strain rate and stress concentration on fracture property of material has been analyzed, which may provide help for improving thermal shock property of material. Thermal shoc...
