Glass-formation and deformation behavior of Ni-Pd-P-B alloy

Ni52Pd26P20B2glassy alloy rods up to 5 mm in diameter were prepared by a copper mold casting technique. The obtained Ni52Pd26P20B2 BMG exhibited rather good glass forming ability and mechanical properties: high strength and reasonable room-temperature plasticity. Two regions of deformation were observed in shear steps on the lateral surface. Propagation of the shear bands was analyzed using video recording and correlated with the stress-strain curve.
