Equilibrium Phases In Cast Alloys Important Notes

1. Equilibrium Phases In Cast Alloys Eutectic Alloys

• It is an alloy for which the component metals have limited solid solubility
• They Examplehibit complete liquid solubility
• Example: silver-copper alloys

2. Equilibrium Phases In Cast Alloys Solute

• It is the substance that is dissolved in a solution
• It is mainly solid

Chloramphenicol Short Question And Answers

Question 1. Eutectic alloys.
Answer:

Eutectic Alloys

• A eutectic alloy is an alloy for which the component metals have limited solubility.
• Silver and copper eutectic alloy is used in dentistry
• In this alloy, the temperature at which the eutectic composition melts is lower than the fusion temperature of silver or copper
• The eutectic liquid composition freezes at a constant temperature
• Such alloys are used when a lower fusion temperature is required.

Question 2. Solid solutions.
Answer:

Solid Solutions

• A solid solution is a solid crystalline phase containing two or more elements at least one of which is a metal, that is intimately combined at the atomic level
• In it, the atoms of two metals are located in the same crystal structure
• Its structure may appear to be entirely homogeneous
• Example: Silver answer palladium
• When the solution of molten silver and palladium is frozen, a solid solution is formed
• The silver atoms enter into the crystal structure of palladium and form a single solid phase.

Question 3. Quenching.
Answer:

Quenching

• Quenching is the rapid cooling of a metal object from high temperature by immersing it in oil or water
• Quenching maintains the mechanical properties of metal which can be lost by slow cooling
• The slower the quench rate, the longer the thermodynamic forces have a chance to alter the microstructure
• Quenching is most commonly performed to harden steel.

Question 4. Solute and solvent.
Answer:

Solute And Solvent

Solute And Solvent Example:

• When sugar is dissolved in water, sugar is the solute, and water is the solvent
• In palladium-silver alloy
• Both metals are completely soluble
• In it, the solvent is the metal whose atoms occupy the majority
