摘要：
Solidus, liquidus, and γ′ solvus temperatures were determined for 11 different γ′-hardened nickel base alloys and for the oxide dispersed commercial alloy MA 6000 by differential thermal analysis (DTA). The solvus temperature of some alloys was additionally determined by dilatometry and metallographic analysis of quenched samples to check the results obtained by DTA. The obtained correlation between the solvus temperature and the concentration of the γ′ phase in the alloy allows the estimation of this temperature and is discussed.
