Abstract

Abstract

The impact property of the centrifugal casting austenite stainless steel Z3CN20.09M no effect on the ratio value Fu/F_m but a significant influence on the impact force and especially on the impact energy.TEM analysis indicates that the shape of dislocations in austenitic has changed,and precipitations have appeared in ferrite.Extrapolation prediction of the impact property is performed by the regression functions established in this study.
