摘要
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。
The strain burst behaviors of [123] Cu-16%Al single crystals at different shear strain amplitudes and loading frequencies were studied in this paper. It was found that strain bursts take place during cyclic deformation when γp1=5.3 x10-5-2.1x10-3, no burst at γp1=6.4x10-3. The frequency of strain burst, the amplitude of strain bursts, B, and the shear stress drop, D, were discussed in terms of the applied strain amplitude and cyclic loading frequency.
