通过测量和分析不同超声施振温度下ZL114A铝合金的致密度,研究超声施振温度对合金致密度的影响,并建立了致密度与超声施振温度和直径的关系。结果表明,在相同的超声施振温度下,随着直径的增大,铝合金的致密度增大;当直径小于9mm时,超声施振温度对铝合金的致密度影响较大,随着超声施振温度升高,铝合金的致密度先下降再上升最后下降,最佳超声施振温度为720℃;当直径大于9mm时,直径对铝合金的致密度影响较大。随着超声施振温度升高,铝合金的致密度先上升后下降,最佳超声施振温度为700℃。
By measuring and analyzing the densities of ZL114A aluminum alloy under different temperatures, the effects of ultrasonic temperature on the alloy densities were studied. The relationship between the densities and temperature and diameter of ultrasonic vibration was established. The results show that the density of the aluminum alloy increases with the increase of the diameter under the same ultrasonic vibration temperature. When the diameter is less than 9mm, the ultrasonic vibration temperature greatly affects the density of the aluminum alloy, When the temperature is increased, the density of aluminum alloy decreases first and then decreases and finally decreases. The optimum ultrasonic vibration temperature is 720 ℃. When the diameter is larger than 9mm, the diameter affects the density of aluminum alloy greatly. With the increase of ultrasonic vibration temperature, the density of aluminum alloy first increases and then decreases, and the optimal ultrasonic vibration temperature is 700 ℃.
