摘要
采用挤压铸造法制造陶瓷纤维增强梯度铝基复合材料 ,通过观察其金相组织、测试其热学性能 ,并对梯度复合材料活塞顶的温度分布及隔热效果进行了计算。结果表明 ,采用挤压铸造法制造出的梯度铝基复合材料 ,梯度层间纤维分布逐渐过渡无分层现象 ;
The squeeze casting technology was used to manufacture gradient aluminum matrix composite reinforced by ceramic fibers,and metallographic structures and thermal properties of the composites were studied. The temperature distribution and heatproof effect of piston top made by this kind of composite was also caculated.It is indicated that a gradual fiber distribution with no delamination and excellent heatproof can be obtained by the squeeze casting for the gradient aluminum matrix composites.
