1. A cermet material, comprising:
a ceramic material; and
an alloy material comprising a transition metal included in a Ni Cr Al alloy that causes no liquid phase below 1310° C., creates over 45% of a gamma phase above 900° C. up to 1310° C., and creates over 30% comprised of a gamma prime phase between 450° C. and 600° C., and the gamma prime phase is characterized by a formula (Ni,Co)x(Cr,Al,Mo)y, wherein x and y are integers, wherein an amount of the Al in the alloy material is 3.1 weight percent to 5.1 weight percent, wherein the transition metal comprises at least one of Co, Mo, and W, wherein a weight percent of the alloy material in the cermet material is 40%, and wherein a ratio of an amount of the ceramic material to an amount of the alloy material is less than 1.5.
