For the purpose of improving the hot workability of 20% Mo-Ni alloy, the melting pattern was established by studying several important parameters. The results are summarized as follows : (1) Deoxidation rate reached up to approximately 80% before melt down. Keeping the molten bath for long times under vacuum deteriorated the hot workability. Therefore, the quick melting pattern should be applied after melt down. (2) There was a clear relationship between the CO reaction rate (R_<CO>=C_M/C_<CO>×100%) during melting process and the hot workability. This shows that the CO reaction rate can be applied as one of the important parameters during melting. (3) The necessary amount of carbon to get the higher deoxidation before melt down could be calculated and - the Co reaction rate could be higher. By these results, we could conduct an ideal melting pattern to get a good deoxidation rate and hot work-ability.
