Interface study of SiCp/6061Al composite

Interface characteristics and reaction mechanism play a major role in determining the properties of Al-SiCp composite. Therefore, the aim of this study is to investigate the interface mechanism of Al-SiCp composite developed by stir casting process. The SiCp is preheated for 2 hrs at 1200 °C prior t...
