【摘要】 采用功率超声对T10钢的凝固过程进行处理,分析了功率超声对T10钢凝固组织和凝固冷却曲线的影响,并在此基础上探索了超声空化和声流效应对T10钢凝固过程的作用机理。结果表明,功率超声能够细化T10钢凝固组织、缩短凝固时间、降低凝固开始温度,超声波功率为700 W时得到均匀细小的等轴晶。更多还原

【Abstract】 The effect of ultrasonic treatment on the solidification characteristic of T10 steel is investigated in the present research.The experimental results show that structure of T10 steel can be refined by ultrasonic treatment.It is also show that the solidification temperature and the solidification time are decreased with the ultrasonic treatment.Based on the aforementioned experiment results,the mechanism of cavitation and acoustic streaming induced by ultrasonic treatment is explored.更多还原
