在蠕变条件下,空穴的生长可以由空位扩散或幂律蠕变控制。这两个增长机制进行检查,参考超塑性铝锌镁合金,它表明,预测的优势幂律增长是一致的,与早期的实验观察在这种材料中的空化。
Under creep conditions, cavity growth may be controlled by vacancy diffusion or power-law creep. These two growth mechanisms are examined with reference to a superplastic Al-Zn-Mg alloy, and it is shown that the predicted dominance of power-law growth is consistent with earlier experimental observations of cavitation in this material.
