    It can be seen from the figure that the grain size of the alloy increases rapidly with the increase of the high temperature treatment temperature. When the treatment temperature is constant, the treatment time is not obvious for the increase of the alloy grain size. However, the treatment temperature should not be too high, such as the treatment temperature is too high, one is to shorten the service life of the high-temperature equipment; the second is to cause too much liquid phase in the alloy, the Co phase volatilization increases, the skeleton collapses, The alloy and the boat are melted together, which is difficult to clean and break. Generally, the high temperature treatment temperature is controlled at about 2000 ° C, and the temperature is kept for 2 hours.
