High strain rate superplasticity of TiC particulate reinforced magnesium alloy composite by vortex method
The stress-strain relationships of TiC paticle reinforced magnesium alloy were examined to evaluate its superplastic properties and compared that with its microstructure. TiCp/Mg alloy composite was fabricated by vortex method. Some samples were extruded after vortex method, some were hot-rolled aft...

| description | The stress-strain relationships of TiC paticle reinforced magnesium alloy were examined to evaluate its superplastic properties and compared that with its microstructure. TiCp/Mg alloy composite was fabricated by vortex method. Some samples were extruded after vortex method, some were hot-rolled after vortex and extrusion. Flow stress of both extruded and hot-rolled Mg-5%Zn /TiCp samples were found to increase linearly with increasing strain rate. With TiC volume fraction of 0.20, a maximum of 300% total elongation was achieved at the strain rates of 0.067 s exp -1 . SEM images show decrease in grain size in the order of vortex samples, extruded samples, and hot-rolled samples. Slopes ( > 0.3) of the best fit curves between flow stress and strain rate indicate that high strain rate superplasticity phenomenon occurred mainly by grain boundary sliding. |
