用气雾化铝合金粉为原料,通过高速压制和烧结工艺获得高密度铝合金,然后对其进行热处理,研究了固溶处理对合金性能的影响,并分析讨论其机理。结果表明,高速压制法制备的铝合金组织均匀、致密。经过固溶和时效处理,合金的强度明显提高,塑性略有下降。经过500℃×30 min的固溶+180℃×360 min的时效,合金的抗拉强度可达206 MPa,屈服强度165 MPa,伸长率2%。
Using the atomized aluminum alloy powder as the raw material, high density aluminum alloy is obtained through high-speed pressing and sintering process, and then heat treated to study the effect of solution treatment on the properties of the alloy, and the mechanism is analyzed and discussed. The results show that the aluminum alloy prepared by high-speed pressing has uniform and compact structure. After solution treatment and aging treatment, the strength of the alloy is obviously improved and the plasticity slightly decreases. After 500 ℃ × 30 min solution + 180 ℃ × 360 min aging, the tensile strength of the alloy can reach 206 MPa, yield strength 165 MPa and elongation 2%.
