| 摘 要： | 采用半固态挤压成形技术制备了Al-Si-Fe耐磨铝合金，分析了合金的微观组织，利用磨损试验研究了合金的耐磨性和磨损失效形式。研究结果表明：半固态挤压成形合金具有细小、均匀的微观组织和良好的耐磨性，磨损失效形式以滑动和磨粒磨损为主。半固态挤压成形的挤压比越高，耐磨性越好；干摩擦条件下半固态合金的磨损质量损失是铸态合金的49．2％，润滑条件下是铸态合金的40．0％。

| Abstract: | Microstructure and wear behavior of Al-Si-Fe alloy prepared by semi-solid squeezing casting have been analyzed. The results show that the alloy possesses fine and uniform microstructure and excellent wear resistance in which slide and abrasive wear are dominant in the wear behavior. The higher the squeezing ratio is, the better the wear resistance is. The weight loss of alloy is 50.98% of that of as-cast alloy under the condition of dry friction, while is 57.77 %of that of ones under the condition of lubricant conditon. |
