| Abstract: | Nickel-free stainless steel powders contained nitrogen were prepared by gas atomization,formed by hot isostatic pressing(HIP),and treated by solution.The HIPed materials have excellent strength,plasticity,and toughness;their tensile strength,yield strength,elongation,area reduction and impact energy are 850 MPa,505 MPa,44.5%,47.5%,and 44J,respectively.After solution treatment at 1 100 ℃ for 1h the plasticity and toughness improve obviously;the elongation,area reduction,and impact energy is 50.0%,55.5%,and 68J,respectively.Experimental data show that the prepared nickel-free stainless steel 17Cr10Mn2MoN has better strength and corrosion resistance than 316L stainless steel. |
