Effect of Center Segregation on Impact Property of Continuous Casting Steel and HAZ
-
摘要: 研究了中心偏析对连铸10CrNi3MoV钢钢板及其焊接接头HAZ表面和心部冲击性能的影响，试验结果表明，中心偏析恶化了中心位置钢板及其HAZ的冲击性能；板厚中心位置试样的冲击功相对于表面位置的有一定下降，下降幅度随试验温度的降低有增大趋势。Abstract: Charpy impact test, in which specimens were cut out from the surface and center of plate, is empoloyed to investigate the effect of center segregation on continuous casting 10CrNi3MoV steel plate and its HAZ at various temperatures.The results show that center segregation deteriorates the impact property of center and the impact value of center specimens are lower than that of the surface specimens, on the other hand,there is a trend that the decrement of the impact value increase as the test temperature dropping.
