STUDY OF HIGH THERMAL STABILITY ALUMINIUM MATRIX COMPOSITE BY HOT FORGING

The processing of powder hot forging to producing high thermal aluminium composite have been studied, as well as the strength and wear stability of SiC particlulate reinforced Al-Fe-V-Si heat resistant aluminium. It was found by the study that the sthength and wear stability of the composite were improved by SiC particulate. The composite was slightly tribodeformed below 250℃, but urgently tribodeformed on 300℃ as wear mechanism changed.
