ABSTRACT:
The porosity of bulk alloys produced by deposition of the components of the alloy from the vapor phase can be reduced if the surface of the alloy is mechanically worked, preferably by a peening action, during the course of the deposition.
Suitable apparatus for mechanically working the surface of the alloy are sets of hammers or flails driven by a suitable means that they strike the surface of the alloy with sufficient force to flatten asperities produced during the course of the deposition and preferably sufficient to remove porosity adjacent to the surface, yet do not at the same time grossly distort the surface of the alloy.
