Ni75AlxV25-x合金沉淀相粗化行为的微观相场模拟
, PP. 239-244
Keywords: Ni75AlxV25-x沉淀,共格应变粗化微观相场
Abstract:
基于共格应变的微观弹性理论和微观相场动力学模型，模拟了Ni75AlxV25-x合金沉淀过程的组织演化和粗化行为。结果表明两种沉淀相颗粒在粗化阶段均表现出明显的取向性。相在其两个不同取向上分布不同，在沿[100]方向的生长趋势明显超过[001]方向，相沿方向排列。先析出相的长大和粗化两个阶段比较分明，后析出相的长大和粗化过程同时进行。两种有序相发生粗化以相邻颗粒碰撞并融合为较大颗粒的方式进行。不同浓度的合金两相析出先后顺序及体积分数不同，但最终形貌基本一致，两相均呈长方块状分布，并且具有(001)//{100}的取向关系。
