摘要：
ccording to China’s energy structure,the development of ultra-supercritical thermal power plants and advanced nuclear energy with high efficiency is an effective way to solve the contradiction between energy shortage and environmental pollution. In order to meet the requirement of long term service in the harsh environment of high temperature,high pressure and corrosive medium,it is urgent to develop new grade material with improved high temperature mechanical properties and oxidation resistance. The newly developed aluminum forming austenitic (AFA)stainless steel shows excellent oxidation resistance and high temperature strength,which is considered as a promising candidate material for key components of advanced energy systems such as ultra-supercritical power plants and supercritical water-cooled reactor. Creep is an important service property for AFA steels application in advanced energy systems,which is closely related to the feature of precipitated phases (including M23 C6 and MC carbide,Laves phase,NiAl phase and FeCr phase),including phase type,size and distribution of precipitates. If the precipitates with good high temperature stability can be controlled to disperse uniformly in the matrix with appropriate size for dislocation pinning effect,then the alloy can obtain excellent high temperature creep properties. AFA was developed based on Super304H,HR3C and TP347HFG. The idea is through adjusting the alloying elements,such as Al,N,Si,Ni, V and B,and controlling the feature of nanoscale precipitated phases,to improve high-temperature creep properties at a low cost. Therefore,it is of great significance to summarize and generalize the control methods of precipitates in order to the development and design of aluminum-containing austenitic stainless steel with better creep properties. In this paper,the control methods of main precipitates in austenitic stainless steel containing aluminum are reviewed,including the regulation of alloying elements and the optimization of thermal mechanical treatment process,and then the relationship between the regulation of precipitates and creep properties is discussed. © 2023 Cailiao Daobaoshe/ Materials Review.
