奥氏体不锈钢应力腐蚀断裂诊断专家系统案例库

Examples-Base for the Expert System of SCC Diagnosis of Austenitic Stainless Steels

摘要: 在收集400多个奥氏体不锈钢应力腐蚀失效的典型断裂事故案例的基础上,建立了应力腐蚀断裂诊断专家系统(Estar-1系统)的案例库,并从这些案例中提取相应的应力腐蚀断裂的经验规则,进行推理设计,运用这个案例库不仅能对奥氏体不锈钢应力腐蚀断裂失效进行辅助诊断,而且能提出相应的防护措施。

Abstract: On the basis of collecting more than 400 cases of histories of stress corrosion cracking(SCC) of austenitic stainless steels(ASS).an examples-base is established for the expert system of SCC diagnosis of ASS(Estar-1 system) in this work.Some empirical rules of SCC are extracted from them and the associated reasoning mode is designed in this base.It can assist the expert system in the SCC diagnosis of ASS and provide corrosive prevention measures.
