A spherically-shaped, microcrystalline Ni-Ti alloy powder having fairly nonhomogeneous particle size distribution and chemical composition was consolidated with shock input energy of 316 kJ/kg. In the process of consolidation, shock energy is preferentially input at particle surfaces, resulting in melting of near-surface material and interparticle welding. The Ni-Ti powder particles were 2-60 μm in diameter (Fig. 1). About 30-40% of the powder particles were Ni-65wt% and balance were Ni-45wt%Ti (estimated by EMPA).Upon shock compaction, the two phase Ni-Ti powder particles were bonded together by the interparticle melt which rapidly solidified, usually to amorphous material. Fig. 2 is an optical micrograph (in plane of shock) of the consolidated Ni-Ti alloy powder, showing the particles with different etching contrast.

Abstract TRIBALOY 400 consists of a hard, intermetallic phase in a softer, cobalt-base alloy matrix. It can be cast or hardfaced. As alloy powder it can be plasma sprayed or blended with other powders for P/M (Powder/Metallurgy) processing. Uses include anti-wear surfaces and bearings or seals operating in corrosive media. This datasheet provides information on composition, physical properties, hardness, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion and wear resistance as well as forming, heat treating, machining, and joining. Filing Code: Co-72. Producer or source: Tribaloy Products.
