能量方程并用有限差分法对其进行了求解,在考虑冲击绝热压缩贡献的基础上计算出了焊接流场中的温度分布.结果表明:在适当的冲击压力下,爆炸粉末烧结过程中微爆炸焊接引起的焊接界面附近的温升将达到材料的熔点而引起材料熔化,颗粒熔化部分仅为其表面很薄的一层;爆炸焊接引起的材料温升随来流速度和碰撞角度的增大而升高. 关键词:爆炸粉末烧结; 爆炸焊接; 绝热压缩; 温度场; 有限差分法; explosive consolidation of powders; explosive welding; adiabatic compression; temperature field; finite difference method; [全文内容正在添加中] ......
