固态收缩与铸造残余内应力关系的研究

A Study on Relation between Solid Shrinkage and Residual Stresses Casting the Poetic Quality

细胞突起呈念珠状变化。焊缝固态收缩对残余应力形成过程的作用

The cells were contraction ; The Contribution of Restrained Solid State Contraction of the Weld on the Welding Residual Stress Forming Procedure

根据焊缝固态收缩对焊接残余应力形成的作用，课题组进一步研究了将滑动摩擦变滚动摩擦的方法来减轻焊件自重拘束以达到调控焊接残余应力的目的。

Based on the influence of the solid shrinkage of weld seam on welding residual stress , value of welding residual stress is decreased through reducing the friction resistance , so the further studies on the measure through changing sliding friction into rolling friction were taken .

建立了结晶器内腔体积变化的平衡方程和结晶器锥度设计数学模型，分析了钢水凝固收缩和固态相变收缩的规律。

The volume balance equation for the mould cave and mathematical model for mould taper design are developed and the law of shrinkage resulting from hot metal solidification and solid phase transformation analyzed .
