控轧钢不同取向冲击试验对形成“断口分离”的影响

The Effect of Different Directions Impact Test of Controlled Rolled Steeled Plate on Fracture Separation

本文通过对螺旋焊管不同方向取样的系列冲击试验，阐述了控轧钢不同取向对冲击功及产生“断口分离”的影响，并就“断口分离”的成因及影响因素进行了初步探讨。

The effect of different divections of controlled rolled steel plate on impact energy and fracture separation are explained. In this paper. through the series impact test sampling from spirally submerged arc welded steel pipe in different directions. In addition. the cause and effeet factor of separation are also discussed.
