Original abstract

Deposits of 92/8 at% Ti/Ni were produced by low-pressure cold spray technique using heated air as working gas. The chemical composition of the 8 mm thick was kept in hypoeutectoid concentration. Samples of the deposited material were annealed at temperatures from 500°C to 1000°C for two hours in argon protective atmosphere. Selected samples were quenched directly from the homogenizing temperature of 1000 and subsequently evolution of precipitated eutectoid was studied. Generally microstructural changes of material character during annealing were evaluated together with changes in the character of fracture behaviour and local micro hardness of the evolved phases.
