Fe‐C‐V‐Cr‐Ni alloy powder is low‐pressure plasma sprayed to produce rapidly solidified alloy deposits based on a stainless cast iron with finely dispersed vanadium carbide particles. The as‐sprayed deposit is made up of γ Fe, α Fe, V 8 C 7 , and Cr 7 C 3 . The fine precipitates of about 0.4 µm in the as‐sprayed deposit are carbide. With increasing heat treatment temperature up to 1 273 K, the carbide particles coarsen. The as‐sprayed deposit has finer vanadium carbide than that of the Fe‐C‐V‐Cr‐Ni cast. With increasing heat treatment temperature above 1 073 K, the coarsening of the vanadium and chromium carbide precipitates and elimination of saturation of matrix with vanadium, chromium, and carbon in the deposit result in the decrease in hardness of the Fe‐C‐V‐Cr‐Ni deposit.
