Open in App
Solution
The hardness of metal affected by the rate of cooling:
- By the affect of rate of cooling either hard metal or soft metals are produced.
- In quenching, which means rapid cooling in the presence of a medium like oil, water at high temperature due to these conditions a metal is converted hard metal.
- Annealing is process in which metals are cooled slowly due to this condition soft metals are produced.
Thus, By quenching( rapid cooling of metals) produce hard metals.
