The results show: when the strain energy is neglected, randomly distributed equiaxed particles were obtained with isotropic characteristics, its coarsening follows the Ostwald ripening mechanism: smaller particles dwindle and larger particles grow;

• 研究发现 :当忽略应变能时 ,沉淀相为随机分布的等轴颗粒 ,呈各向同性特征 ,其粗化遵循奥斯瓦尔德熟化机制 :小颗粒溶解 ,大颗粒长大。
