| Abstract: |
A stainless steel - commercial purity iron composite is being considered for biodegradable stent applications. The composite material has been fabricated by cold spray and then subjected to annealing temperature to improve the ductility. Annealing above 1000 centigrade eliminated work hardening and also led to 'sintering' drastically increasing the ductility. It was found that the strength of the annealed stainless steel cold sprayed material had a higher strength than the annealed 100% commercial purity iron, but the addition of only 20% stainless steel was sufficient for the composite to reach the strength of the 100% stainless steel specimen.
