报告题目：Micro deformation and damage mechanisms during creep and fatigue in an advanced heat resistant austenitic stainless steel

报告摘要：Sanicro 25 material is a newly developed advanced heat resistant austenitic stainless steel. This material shows a combination of good resistance to steam oxidation and flue gas corrosion, and higher creep rupture strength than any other austenitic stainless steels available today. It is an excellent candidate material for high efficient coal fired power plants with a steam temperature up to 700°C. This lecture will provide an overview on the study of creep, fatigue and creep-fatigue interaction behavior in this alloy for structure integrity analysis. It will mainly focus on micro deformation and damage mechanisms during these processes by using TEM and SEM/EBSD/ECCI analysis.
