摘要
A system study on aging behavior and the influence of heat treatment on mechanical property of Mg8Li1Al and Mg11Li3Al alloys has been carried our. The results show that the alloys described above have apparent aging behavior and over aging happens even at room temperature. theta (MgLi2Al) phase has been identified when hardness reaches aging peak. With the increase of aging temperature, the size of theta (MgLi2Al) phase becomes larger apparently and over aging happens. Heat treatment can raise tensile strength of Mg8Li1Al and Mg11Li3Al alloys, but the elongation decreases greatly.
