The correlation among microstructural parameter and dynamic strain aging (DSA) in influencing the mechanical properties of a reduced activated ferritic-martensitic (RAFM) steel

Journal Article


Abstract


  • The additional effect of the dynamic strain aging (DSA) on the microstructural parameters in influencing the yield strength was analyzed through comparing the difference between the experimental yield strength and the calculated value at room temperature (RT) in 9Cr-1.7W-0.1C reduced activated ferritic-martensitic (RAFM) steel samples treated under two different heat treatments. Different heat treatments leaded to the variation of the microstructural parameters of this steel. Then the contributions of these microstructural parameters and DSA on the tensile properties at elevated temperatures were studied with the modified Crussard–Jaoul (C–J) analysis based on the Swift equation.
