中文摘要：

采用DEFORM-3D软件模拟研究了模具温度、压下速度等因素对半固态6061铝合金触变模锻过程。结果表明：6061合金在650℃料温,400℃模温,50 mm/s压下速度时半固态金属模锻成形过程较为理想;半固态模锻件经T5处理后,硬度（HV）可达到2166 MPa,高于常规低压铸件170.5%,模拟结果与实际符合很好。

英文摘要：

The effects of the mold temperature and the forming speed on semi-solid 6061 alloy forging were studied by means of software DEFORM-3D.The results show that when the temperature of semi-solid slurry is kept at 650 oC,the mold temperature 400 oC,and the forming speed 50 mm/s,an excellent part can be obtained.The HV hardness value of semi-solid forging parts with T5 treatment is 2166 MPa,170.5% higher than that of the normal low-press cast parts.The simulation results are well in agreement with the experiment.
