Enhanced mechanical properties of magnesium alloy seamless tube by three-roll rotary piercing with severe plastic deformation

•Mg alloy seamless tubes were successfully fabricated by three-roll rotary piercing process.•The grains of MASTs were refined to 12.5% of the original grain size by TRPP.•The UTS and elongation were all improved significantly after TRPP.•The enhanced elongation was attributed to GBS and the easier a...
