摘要: Abstract Tensile behavior of a 329LA lean duplex stainless steel at room temperature is investigated after annealing different temperatures. The austenite composition and thereby, its stability depend on the temperature. For recrystallized alloys, increases with Therefore, martensitic transformation effectively suppressed during cooling deformation, which results in low tensile strength strain hardening rate, when annealed higher Accordingly, transformation-induced plasticity more pronounced alloys lower During α′ -martensite forms blocky morphology absence deformation bands indexed as an hcp phase. Thus, it suggested that directly transforms to rather than via due relatively high driving force for present alloy.
