A direct manufacturing technique involving rapid solidification processing uses a reaction between a metallic molten pool and a reactant gas in an inert atmosphere to form alloys with improved desired properties. By utilizing rapid solidification techniques, solubility levels can be increased resulting in alloys with unique mechanical and physical properties. Laser deposition of alloys in atmospheres of varying reactant content produce significant strengthening without cracking. In addition, these materials have very high hardness values for hard face coating and functionally graded materials applications.
