| 摘 要： | 使用自制的交错式功率超声双振动头装置,处理A356铝合金流动熔体获得半固态浆料,研究了1000和1500W超声换能器前后排布流道、不同浇注温度和不同流道倾斜角度对A356熔体处理所获半固态组织的影响规律。结果表明,双振头斜流道对晶粒有细化作用,不同的倾斜角度对A356半固态组织细化程度不同。施振温度为620℃,流道倾斜角度为40°时,初生相晶粒最为细小,球化效果最好。

| Abstract: | We have developed an interlacing type double power ultrasonic vibration heads equipment to treat A356 aluminum alloy melt to obtain semi-solid slurry.Effects of different pouring temperature and different inclined angle of flow runner as well as front and back arrangement of flow runner of ultrasonic transducer with 1000W and 1500W on microstructure of semi-solid A356 alloy slurry were investigated.The results show that obvious refinement of microstructure of A356 alloy can be observed by double ultrasonic ... |
