| Popis: | The poor hot workability of aluminum matrix composites (AMCs) severely limits their engineering use. Here an abnormal hot deformability phenomenon was observed in a metallic glass-particle-reinforced AMC in which the composite shows higher strength at room temperature and lower strength at higher temperatures than the monolithic Al-7075 alloy, indicating excellent hot workability. It reveals that the metallic glass at high temperature may be as a soft binder to release the local stress concentration during deformation owing to drop in viscosity. This study provides new opportunities for designing and achieving good workability in AMCs for advanced structural applications. |
