What is the difference between cold, warm, and hot forging?
Expert Solution & Answer
To determine
What is the difference between cold, warm, and hot forging?
Explanation of Solution
| Cold forging | Warm forging |
Hot forging |
| Cold forging includes impression die forging or true closed die forging having lubricant and circular dies at or around thenormal temperature. | The temperature for warm forging of steel varies from above normal temperature to below the recrystallization temperature. |
Hot forging refers to the plastic deformation of metal at strain rate and a temperature which help in recrystallizingconcurrently with the process of deforming. This way, strain hardening at recrystallizing temperature is evaded. |
