中文摘要	die-cast mg-4al-4re-0.4mn (re = ce-rich mischmetal) and mg-4al-4la-0.4mn magnesium alloys were prepared successfully and their microstructure, tensile and creep properties have been investigated. the results show that two binary al-re phases, al11re3 and al2re, are formed along grain boundaries in mg-4al-4re-0.4mn alloy, while the phase compositions of mg-4al-4la-0.4mn alloy mainly consist of alpha-mg phase and al11la3 phase. and in mg-4al-4la-0.4mn alloy the al11la3 phase occupies a large grain boundary area and grows with complicated morphologies, which is characterized by scanning electron microscopy in detail. changing the rare earth content of the alloy from ce-rich mischmetal to lanthanum gives a further improvement in the tensile and creep properties, and the later could be attributed to the better thermal stability of al11la3 phase in mg-4al-4la-0.4mn alloy than that of al11re3 phase in mg-4al-4re-0.4mn alloy.
