1. Formation of marten site, which produces very hard and brittle steel
2. Retention of austenite, at room temperature, which a very ductile and tough steel
3. Formation of large carbide particles near the grain boundaries in the steel, which makes the steel brittle very tough
4. Retention of austenite, even at room temperature, which gives very brittle and hard steel
Formation of marten site, which produces very hard and brittle steel
1. The number density of dislocation in the bar will be reduced, but the shape of the bar remains unchanged
2. The bar will straighten out again, since dislocations are eliminated by the annealing
3. The bar will straighten out gain, since the number of dislocation is increased by annealing
4. Nothing changes on an atomic, micro structural or macroscopic scale in the bar. The bar just gets hot
The number density of dislocation in the bar will be reduced, but the shape of the bar remains unchanged
