研究了应变幅和加载频率对［123］Cu－16％Al单晶在循环形变中的应变突发行为的影响．结果表明，在应变幅γp1＝5．3×105－5－2．1×10－3范围内，循环形变过程中均发生应变突发；在γp1＝6．4×103时，循环形变过程中未发生应变突发讨论了应变幅和加载频率f与应变突发频率n，应变突发量B和应变突发时应力降低值D的关系
The effect of strain amplitude and loading frequency on the strain burst behavior of [123] Cu-16% Al single crystal during cyclic deformation was investigated. The results show that all of the sudden strain occurred during the cyclic deformation in the range of γp1 = 5.3 × 105-5-2.1 × 10-3. When γp1 = 6.4 × 103, the cyclic strain No strain burst occurs The relationship between strain amplitude and loading frequency f and strain burst frequency n, strain burst B, and stress drop D at strain burst are discussed
