摘　　要：The 2024 aluminum alloy was prepared with different ultrasonic processes.Effects of ultrasonic treatment parameters including ultrasonic power,treatment time,treatment temperature,and frequency resonance,as well as C_(2)Cl_(6) degasser on degassing of the 2024 aluminum alloy were investigated.Results indicate that increasing ultrasonic power at the same ultrasonic treatment time can improve the degassing effect.The optimum degassing efficiency can be obtained under the resonant ultrasound condition.With the combination of 1%C_(2)Cl_(6) addition and 150 W ultrasonic treatment for 40 s,the hydrogen content of the alloy is decreased by 52.9%.At the same time,the tensile strength and elongation are increased by 28.3%and 92.3%,respectively,and the yield strength is slightly increased by 6.7%.The degassing mechanism is also discussed.
