Abstract

In recent years, Manganese-nickel alloys have been studied by many researchers due to their unique magnetic properties. The purpose of this study was to investigate the effect of pressure of the compartment on the manganese Evaporation process and to determine critical and inhibit Evaporation pressures and temperature for this element in Manganese-nickel alloys (70Mn-25Ni-5Cr and 40Mn-55Ni-5Cr). In this regard, Manganese-nickel alloys in a vacuum induced melting furnace, under the atmosphere of argon by positive pressure (0. 4, 0. 6, 0. 8, 1, 2, 2. 5, 3, 4, and 4. 5) bar melted at temperatures of 1450, 1550 and 1650° C. For the above conditions, the rate of Evaporation was calculated and illustrated by plotting Evaporation rate graphs with pressure, the critical pressure and impeding pressure for manganese Evaporation determined. The results showed that pressures of 1 bar and 3 bar were sequencly critical pressure and impeding pressure for manganese Evaporation in Manganese-nickel alloys. It was also found that the increase in melting temperature caused an increase in the Evaporation rate, but the critical pressure and inhibit pressure remained unchanged for manganese Evaporation in the alloys.
