Embodiment 3
[0017] Embodiment three: the carbon-containing nickel-iron alloy material is composed of the following chemical components by weight percentage: nickel 29%, iron 61%, carbon 5%, cobalt cobalt 1%, silicon 0.17%, phosphorus 0.08%, sulfur 0.028%, chromium 0.32%, gallium 0.45%, strontium 0.3%, rhenium 0.18%.
[0018] A carbon-containing nickel-iron alloy and a preparation process thereof, comprising the following steps:
[0019] (1) take described raw material by weighing above-mentioned percentage by weight and mix at a high speed in a high-speed mixer to obtain alloy powder, and the high-speed mixing time is 30min-60min;
[0020] (2) Put the mixed raw materials into the impurity removal machine for refining, sieve for 5-10 minutes, and sieve out the high-density mixture,
[0021] (3) Put the mixed alloy powder into a vacuum melting furnace and melt for 2-5 hours at a temperature of 640-720°C;
[0022] (4) Increase the temperature in the vacuum melting furnace to 1120-1150° C.,...
