850级钢焊缝的微观组织与力学性能
Microstructure and Mechanical Properties of 850 Class Steel Welding Line
摘要
Abstract
The microstructure and mechanical properties of 850 class steel welding line,which was prepared by gas metal arc welding,were studied.The results show that the microstructure of the welding line are interwine state lath martensite and tine paralleled lath martensite.And the toughness of the weld metal increase enormously due to interwine state lath martensite and retained austenite.关键词
