Q. Isothermal forging is also known as cold forging operation.
✅ Correct Answer: (B)
false
Explanation: isothermal forging is a hot forging operation in which the metal part is maintained at some high temperature. the forging dies are also maintained at the same high temperature. in this method, the metal flows readily that reduces the amount of force required. but this process is expensive than the conventional forging and mainly used for materials like titanium and super-alloys.
