AbstractStainless steel (316L) powder is mixed with commercially pure iron (CP Fe) (by weight of CP Fe in the range between 20% and 80%) and cold sprayed onto a steel substrate to produce a metal composite designed primarily to exhibit controlled properties. For these composites, porosity is very low, but annealing between 600°C to 1100°C for an hour reduces porosity; the lowest porosity was exhibited by the 50-50 composite. Annealing also 'sinters' the interparticle interfaces, leading to vastly improved fracture properties. The fully annealed single component 316L material exhibits a much higher strength compared to the fully annealed CP Fe specimen, but the addition of only 20% 316L to CP Fe leads to a composite with the same fully annealed strength Jevel as that of the 316L.
