为研究脱气工艺对铸造铝合金的影响，进行了旋转弯曲疲劳试验。采用脱气工艺降低了套管铝合金的铸造缺陷。结果表明，除气工艺对减少铸件缺陷有显著的效果，除气合金在全疲劳寿命范围内的疲劳强度和10次循环疲劳强度均比未除气合金有所提高。
Rotating bending fatigue tests were performed in order to investigate effects of degassing process on a casting aluminum alloy. Degassing process was used for decreasing casting defects in casing aluminum alloys. It was clear that the degassing process had a remarkable effect for the reduction of casting defects and the fatigue strength of degassed alloys was improved in the whole range of fatigue life and the fatigue strength at 10 cycles in comparing with those of non-degassed alloys.
