Ti含量对压铸A380合金缸壳体力学性能的影响

Ti Content on Improvement of Mechanical Properties of Lower Crankcase

针对新一代发动机所用的A380合金下缸壳体,在性能上对材料的抗拉强度及屈服强度要求更高,提出了满足-3σ的全新目标。为此,通过不断调整铝液的化学成分及压铸工艺参数,确保最终目标指标得到实现。

In view of the lower cylinder housing for the new generation engine,the tensile strength and yield strength of the alloy are the higher than other products in performance.Therefore,the final target can be achieved by constantly adjusting the chemical composition of liquid aluminum and the process parameters of die casting.
