What is the significance of the plateau observed in the cooling curve of a pure metal during solidification?
What is the significance of the plateau observed in the cooling curve of a pure metal during solidification?
The plateau indicates that the temperature remains constant while the metal solidifies, revealing the energy release known as latent heat of fusion.
In a 50Cu:50Ni composition at 1300°C, what phases are present according to the equilibrium phase diagram?
In a 50Cu:50Ni composition at 1300°C, what phases are present according to the equilibrium phase diagram?
The phases present are a mixture of liquid copper and a nickel-rich solid.
How do the liquidus and solidus points on the cooling curve for an alloy differ from those of a pure metal?
How do the liquidus and solidus points on the cooling curve for an alloy differ from those of a pure metal?
In an alloy, the liquidus and solidus points are separate, indicating a range of temperatures for solidification as opposed to a singular melting point in pure metals.
