摘要
Abstract
The macroscopic,chemical composition,microstructure and fracture were investigated,and the 600 MW power plant boiler water wall tube leakage reasons were analyzed.The results show that the key reason of the water wall tube leakage is the fatigue crack of corrosion medium and the thermal stress associative action.The crack is extension from the outer to the inner wall,and it is mainly the wedge intracrystalline failure.关键词
