摘　　要：介绍了应变强化基本原理,并分析奥氏体不锈钢压力容器应变强化两种模式——常温应变强化Avesta模式和低温应变强化Ardeform模式。同时,分析比较几种压力容器标准关于奥氏体不锈钢材料的许用应力选取,其中欧盟EN13445压力容器标准奥氏体不锈钢屈服强度按σ1.0选取,材料安全系数取值较低,非常实用。The basic principle of strain strengthening was presented, and two models of the strain strengthening of pressure vessels of austenitic steel-the strain strengthening Avesta model at normal atmospheric temperatures and the strain strengthening Ardeform model at low temperatures,were analyzed. Meanwhile, the selections of permissible stress of austenitic stainless steel were compared and analyzed in several pressure vessel standards. EN13445 Pressure Vessel Standard chooses σ1.0 as the yield strength of austenitic stainless steel. In this condition, the value of the safe factor of the materials is low and practical.
