Abstract

The dynamic behaviors of tungsten heavy alloy (WHA) processed by hot-hydrostatic extrusion (HE) and hot torsion (HT) were investigated. The HE + HT WHAs exhibit significant improved susceptibility to forming adiabatic shear bands (ASBs) and a remarkably high flow stress of 2400 MPa under uniaxial dynamic compression. With increasing plastic strain of HT, an obviously increasing tendency of localized shearing was observed. Elongated subgrains with an average width of 200-300 nm bonded together and formed parallel lamellar bands within the ASBs of WHA. Crown
