CRITICAL PROCESSES TO MODEL IN PREDICTING SCC RESPONSE IN HOT WATER

摘要

Structural materials have a fundamental susceptibility to SCC in high temperature water, and extensive efforts have been made to quantify their specific response as a function of material and condition, water chemistry, temperature, stress, etc. There are many primary variables, and dozens of important factors, all of which are interdependent in establishing SCC response. The only comprehensive way of tackling this problem is to identify the underlying processes that control SCC, which provides a fundamental framework for understanding the myriad of inter-dependent factors. This paper discusses the processes that must be understood and modeled, and compares various approaches in this quest.
