| Abstract: | The hardness and microstructure of a new casting Al-Cu alloy in different aging conditions were analyzed.The results showed that the new casting Al-Cu alloy demonstrated an excellent aging hardening characteristic.When the holding time was 4h,the hardness can reach a higher value.After aging treatment the grain size of the samples was significantly reduced.There were a lot of precipitates on the grain boundaries and in the inside of grains. |
