| 英文摘要 | Mg-6al-4re-0.4mn (mass fraction, %, re=ce rich mischmetal) alloy was prepared by steel mould casting technique. solid solution and artificial aging (t6) were carried out. the microstructure and mechanical properties of both as-cast and t6 treated alloys were investigated at room temperature and 423 k. it is found that the intermetallic compounds of the as-cast and t6 treated alloys were mainly composed of al11re3, mg17al12 and a(16)remn(6). the vickers hardness (hv) of the as-cast alloy is 63 and it increases to 70 after t6 heat treatment. t6 heat treatment plays a slight role in the tensile properties at room temperature, but the yield strength and elongation of t6 state at 423 k are distinctly improved. the yield strength and elongation of the as-east alloy at 423 k are 71 mpa and 18%, respectively, and the values increase after t6 heat treatment, which is attributed to al11re3, mg17al12 and al6rf-mn-6 precipitates that impede the dislocation movement and gliding of grain boundaries effectively. |
