Precipitation and Properties at Elevated Temperature in Austenitic Heat‐Resistant Steels—A Review

Abstract: The austenitic heat‐resistant steels are significant materials used in boilers and nuclear reactors, owing to the excellent creep, fatigue, corrosion resistance, and mechanical properties. The precipitation and properties degenerate with the increasing temperature. It is necessary to clarify the main precipitation and properties under the service situation. Herein, the characteristic of main precipitation and the potential degraded mechanism of creep, fatigue, oxidation resistance, and corrosion resistance at … Show more

“…Austenitic stainless steels (ASS) exhibit complex dislocation structures under fatigue, creep, and creep-fatigue interaction condition, which are mainly the cellular structure [1][2][3][4] , channel/wall structure, persistent slip bands 5,6 , vein/labyrinth dislocation structures 7 , ladder structure 8 , planar slip bands 9 , the corduroy structure 10 . There are two main slip modes of dislocation in ASS under plastic deformation known as the cross slip and the planar slip.…”
