A copper-nickel alloy of composition (40% Ni-60% Cu) is slowly heated from a temperature of 1200°C: 1. a) At what temperature does the first liquid phase form? b) What is the composition of this liquid phase? c) At what temperature does complete melting of the alloy occur? d) What is the composition of the last solid remaining prior to complete melting? Composition (at% N) 100 0 1600 2800 1500 1453°C Liquid 2600 Soldus line Liquidus line 1300 - 2200 120아ㅡㅡㅡㅡㅡ...
Need help on this thermodynamics question. Thanks
