摘要
为了优化热等静压扩散连接的工艺参数 ,应用有限元计算法建立了合理的数学模型 ,对 930℃ / 6 5MPa热等静压条件下不同时刻的铍 /不锈钢扩散连接的浓度场进行了计算机模拟。然后将 2 .5h热等静压扩散焊浓度场的模拟结果与试验测定结果作了分析比较 ,在此基础上进一步探讨了扩散宽度与扩散时间的关系。结果表明 ,模拟的浓度曲线与试验测定结果基本吻合 。
In order to provide the best technic parameter for the HIP process ,the diffuse-bonding concentration field of Be/stainless Steel under a certain condition was simulated by the finite element method. More study had been done on the relationship between the diffuse distance and the diffuse time. The results show that the simulative consistency curves fit with the experience ones well and there is a parabola relationship between the diffuse distance and the diffuse time.
