中文摘要:利用自行设计和研制的一套超声振动装置,对制备过程中的工艺参数,如:超声导入温度,超声输出功率和超声处理时间,对半固态AZ61镁合金组织的影响进行了分析;通过正交实验设计获得了超声制备AZ61镁合金半固态浆料的最佳工艺方案,即:超声导入温度为605℃,超声处理功率为900 W,超声作用时间为60 s。
英文摘要:Using the ultrasonic vibration equipment designed and studied by ourselves, the effects of technological parameters on the semi-solid microstructure of AZ61 magnesium alloy were analyzed, such as the melt temperature, the output power of ultrasonic stirring and the ultrasonic treatment time. The optimal preparing conditions obtained by orthogonal design are as follows: the optimum melt temperature is 605 ℃, the output power of ultrasonic stirring is 900 W and the ultrasonic treatment time is 60 s.
