摘要
Abstract
In order to identify the change of mechanical properties along the wall thickness of long-years-served boiler tubes,a group of 3-parameter data including micro area hardness,indentation remaining depth and plastic work along the wall thickness of a finishing superheater tube which had serviced for 10 5 h,were obtained by depth-sensing indentation (DSI)testing technology.Then by introducing M Dao’s method,the yield strength of certain area was deduced.So the strength change trend along the tube wall thickness could be revealed quantitatively.关键词
