摘要
采用超声波振动装置,研究了浇注温度对ZL101铝合金组织和性能影响。结果表明,超声振动可以使ZL101铝合金获得细小的等轴晶凝固组织。随着浇注温度降低,ZL101铝合金凝固组织逐渐得到细化,且分布均匀。超声振动的施加有利于ZL101铝合金等轴晶组织的细化,并且对其强度、硬度等各方面性能均有所改善。
The effects of ultrasonic vibration on the microstructure and properties of ZL101 alloy were investigated.The results show that the fine equiaxed grain in ZL101 alloy can be generated by ultrasonic vibration.The grain size in ZL101 alloy is refined and homogenized increasingly with the decrease of pouring temperature.The application of ultrasonic vibration is helpful to refining the equiaxed grain and improving its properties such as strength and hardness.
