The fatigue property of the notched part can be improved significantly by introducingcompressive residual stress resulting from surface plastic deformation at t
Fariabh strain rate tension tests for 4 metallic materials show that as the strain rate in creases the strain hardening exponent n decreases.The trend follows a
Because Nb accelerates the uniform distribution of MC phase and the grain refinement,aswell as,increases the amount and stability of γ-phase,the tensile streng
