采用超声振动凝固法使铁在较低的温度下快速溶入铝液,制得的Al-Fe合金显微组织中具有均匀而细小的短棒状FeAl_3相。根据融液中超声空蚀效应和局部温升效应,讨论了超声作用下铁的快速溶解机制,并展望了采用该法制备新型合金的应用前景。 Ultrasonic vibration coagulation method was adopted to rapidly dissolve iron into molten aluminum at lower temperature. The prepared Al-Fe alloy microstructure had a uniform and small short rod-like FeAl_3 phase. According to the effect of cavitation ultrasonic cavitation and local temperature increase, the mechanism of rapid dissolution of iron under ultrasonic irradiation was discussed, and the application prospects of the new alloy prepared by this method were prospected.
