Abstract:
It is detailed that the densities, microstructures, and mechanical properties of the multi layer spray deposited Al-Fe-V-Si pipe blank after being extruded, spun or rolled. With the densification, material density and mechanical properties are promoted distinctly, the boundaries and cavities in the deposits are welded and the microstructure reaches even. The results show that the multi layer spray deposited pipe blank could be processed by such technologies as extrusion spin or extrusion roll.
