摘要
为实现对TC4钛合金棒材超声声速的控制,对比研究了轧制和热处理(包括固溶处理、固溶时效处理和三重热处理)对TC4钛合金棒材超声声速的影响。结果表明:轧制温度和变形量对TC4钛合金棒材超声声速影响较大,随着轧制温度的降低和轧制变形量的增大,超声声速逐渐降低;热处理温度和冷却方式对棒材超声声速也有一定的影响,随着固溶温度的升高和时效温度的降低,超声声速逐渐升高;与固溶时效处理相比,经三重热处理后的棒材超声声速更高,且第一重热处理采用水冷的棒材最终超声声速高于采用空冷的棒材。
To achieve ultrasonic velocity control of TC4 titanium alloy bars,the effects of rolling and heat treatment(including solution heat treatment,solution aging heat treatment and triple heat treatment)on the ultrasonic velocity of TC4 titanium alloy bars were studied.The results show that rolling temperature and deformation degree have a significant impact on the ultrasonic velocity of TC4 titanium alloy bars.With the decrease of rolling temperature and the increase of rolling degree,the ultrasonic velocity decreases gradually.The heat treatment temperature and cooling method also have a certain impact on the ultrasonic velocity of the bars.With the increase of solution temperature and the decrease of aging temperature,the ultrasonic velocity increases gradually.Compared with solution and aging heat treatment,the ultrasonic velocity after triple heat treatment is higher,and the final ultrasonic velocity of the bars cooled by water quenching after the first heat treatment is higher than that of the bars cooled by air.
