High temperature tensile deformation in single-pass friction stirred AZ31 alloy
نویسندگان
چکیده
The present study has expounded the effect of high temperatures on tensile deformation AZ31 magnesium alloy processed through a single-pass friction stir processing (FSP). major operation parameters, namely rotation speed and traverse FSP tool, were varied which led to extensive dynamic recrystallization (DRX) in zone (SZ) engendering maximum grain refinement about 63% as compared base metal. lowest average size ? 5.66 ?m was attained after single pass. Optical microscopy (OM) followed by uniaxial tests at three different 350, 400 450 ºC constant strain rate 1.3 × 10-3/s. As temperature raised, flow stress reduced appreciable increments material’s elongations. maximal elongation fracture 160% observed (FSPed) sample possessing finest grains.

متن کاملTHE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES
AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...
متن کاملFriction and Molecular Deformation in the Tensile Regime
Recent molecular level studies of energy dissipation in sliding friction have suggested a contribution from adhesive forces. In order to observe this directly, we have constructed a scanning force microscope with decoupled lateral and normal force sensors to simultaneously observe the onset of both friction and attractive forces. Measurements made on self-assembling alkanethiol films with chemi...
متن کاملMicrostructure and High Temperature Deformation Behavior of Cast 310S Alloy
High temperature deformation behavior of cast 310S stainless steel has been investigated in this study by performing tensile and compression tests at temperatures from 900 to 1200C. Rectangular ingots of which the dimensions were 350×350×100 in millimeter were cast using vacuum induction melting. Phase equilibrium was calculated using the FactSage®, thermodynamic software and database. Thermal ...
