简介:研究定向凝固条件下凝固参数(生长速率v和温度梯度G)对Mg-2.35Gd合金显微组织及室温力学性能的影响。采用金属液淬技术,在温度梯度G为20、25、30K/mm,生长速率v为10-200μm/s条件下通过高梯度Bridgman定向凝固炉制备试样。研究表明,实验合金的显微组织均为胞晶组织,胞晶间距λ随温度梯度和生长速率的增大而减小,其非线性拟合关系分别为λ=136.216v^-0.2440(G=30K/mm)、λ=626.5630G^-0.5625(v=10μm/s),均与Trivedi模型较吻合。随温度梯度和生长速率的增大,合金室温抗拉强度逐渐提高,伸长率逐渐降低。同时,合金室温抗拉强度高于相同冷却速率条件下自由凝固试样的室温抗拉强度。
