摘要：

采用不同的始锻温度和终锻温度进行了建筑用铝基复合材料的锻造成形，并进行了耐磨损性能和力学性能的测试与分析。结果表明：随始锻温度从450 ℃提高至550 ℃，终锻温度从350 ℃提高至430 ℃，建筑用铝基复合材料的磨损体积先减小后增大、抗拉强度先增大后减小、断后伸长率变化不大，耐磨损性能和力学性能呈先提升后下降的趋势。当始锻温度为500 ℃时，建筑用铝基复合材料的磨损体积和抗拉强度分别较450 ℃始锻时减小了17×10-3 mm3和增大了37 MPa；当终锻温度为410 ℃时，建筑用铝基复合材料的磨损体积和抗拉强度分别较350 ℃终锻时减小了15×10-3 mm3和增大了30 MPa。建筑用铝基复合材料的始锻温度和终锻温度分别优选为500和410 ℃。

The aluminum matrix composites used in building were forged with different initial forging temperatures and final forging temperatures, and the wear resistance and mechanical properties of samples were tested and analyzed. The results show that with initial forging temperature varying from 450 ℃ to 550 ℃ and final forging temperature varying from 350 ℃ to 430 ℃, the wear volume of aluminum matrix composites used in building first decreases and then increases, the tensile strength first increases and then decreases and the elongation rate after fracture changes little, therefore the wear resistance and mechanical properties first increase and then decrease. When the initial forging temperature is 500 ℃, the wear volume and tensile strength of aluminum matrix composites used in building are reduced by 17×10-3 mm3 and increased by 37 MPa, respectively, comparing with the initial forging at 450 ℃. However, when the final forging temperature is 410 ℃, the wear volume and tensile strength of aluminum matrix composites used in builiding are reduced by 15×10-3 mm3 and increased by 30 MPa, respectively, comparing with the final forging at 350 ℃. Thus, the optimized initial forging temperature and final forging temperature of aluminum matrix composites used in building are 500 ℃ and 410 ℃, respectively.
