Question 1

peritectic reaction

Answer 1

is one that occurs at a point where three phases exist at equilibrium at which heiling from below the peritectic temperature a single solid phase will transform into a liquid and differint solid phase.

Question 2

What phase would you expect a low carbon steel to be composed of at room temperature

Answer 2

side ways not -ferrite and probably some Fe3C

Question 3

List two unique characteristics of a eutectic alloy and/ or it’s phase diagram

Answer 3

The eutectic reaction occurs at a single line between the solubility limits of the two components

They exhibit a low melting point at the eutectic composition and temperature

Question 4

Briefly explain the difference between hardness and hardenability

Answer 4

Hardness in the measure of localize resistance to plastic deformation and hardenability is a measure of how atoms ability to become hardened as a result of martensite transitions

Question 5

What is the principle difference between natural and artificial aging processes

Answer 5

Natural aging occurs at normal ambient temperatures while artificial aging occurs at elevated temperatures
