Grain size and particle dispersion effects on the tensile behavior of friction stir welded MA956 oxide dispersion strengthened steel from low to elevated temperatures

Abstract

This paper shows the dependence of tensile behavior of friction stir welded oxide dispersion strenghtened steel (MA956) on testing temperature and welding parameters. Eight welding conditions were utilized and three produced consolidated defect-free welds in MA956 plate material. Tensile samples were prepared from the welded plate and were subjected to tensile testing with a strain rate of....
