A method of coating a substrate with cryo-milled, nano-grained particles includes forming a face-centered-cubic gamma matrix comprising nickel, cobalt, chromium, tungsten and molybdenum, adding a dispersion strengthening material to the gamma matrix to form a first mixture, cryo-milling the first mixture to form a second mixture to form a nano-grained structure, and cold spraying the second mixture onto a substrate to form a coating having a nano-grained structure.

1. A product for use in a turbomachine produced by a process comprising the steps of: forming a face-centered-cubic gamma matrix comprising nickel, cobalt, chromium, tungsten and molybdenum;adding a dispersion strengthening material to the gamma matrix to form a first mixture;cryo-milling the first mixture to form a second mixture having intrinsically dispersed carbides, nitrides, carbo-nitrides, oxy-carbo-nitrides and oxides, the second mixture having a nano-grained structure; andcold spraying the second mixture onto a substrate to form a coating, the coating having a nano-grained structure. 2. The product formed by the process of claim 1, wherein forming the gamma matrix further comprises adding at least one of aluminum and titanium. 3. The product formed by the process of claim 1, wherein adding the dispersion strengthening material comprises adding at least one of alumina, yttria, zirconia, hafiiia, tungsten carbide, and chromium carbide to the gamma matrix. 4. The product formed by the process of claim 1, wherein adding the dispersion strengthening material comprises heat-treating the gamma matrix to form a gamma-prime precipitate to form the first mixture. 5. The product formed by the process of claim 1, wherein cryo-milling the first mixture comprises cryo-milling the first mixture in a cryo-milling media chemistry including a liquefied inert gas. 6. The product formed by the process of claim 1, wherein forming the gamma matrix includes admixing about 30-50% nickel, about 10-30% cobalt, about 4-10% molybdenum, about 4-10% tungsten, and about 10-30% chromium. 7. The product formed by the process of claim 1, wherein forming the gamma matrix further comprises at least one of about 0-6% rhenium, about 0-6% niobium, about 0-6% tantalum, about 0-5% aluminum, and about 0-5% titanium.
