<p>With great corrosion resistance and mechanical property, ferrite-austenitic duplex stainless steel has been applied to components in corrosive environments such as sea water pumps. Due to different coefficient of thermal expansion and elastic modulus between the two phases, phase stress occurs after heat treatment or material processing such as casting, forging and machining, which may affect material properties such as fatigue strength, welding stability and so on. In this study, phase stress distribution along thickness direction of duplex stainless steel hollow cylinders fabricated by centrifugal casting was measured by pulsed neutron diffraction using time-of-flight (TOF) method. Also lattice strain and phase stress evolution were discussed by in-situ neutron diffraction measurement during tensile test. All these measurements were conducted at Japan Proton Accelerator Research Complex (J-PARC).</p>
