Why is the work material often heated before forming in deformation processes?
Why is the work material often heated before forming in deformation processes?
- To reduce the temperature of the material
- To decrease the ductility of the material
- To increase ductility and for other reasons (correct)
- To increase the yield strength of the material
What is the primary requirement for a material to be shaped through deformation processes?
What is the primary requirement for a material to be shaped through deformation processes?
- The material must be highly brittle
- The material must be extremely hard
- The material must be sufficiently ductile (correct)
- The material must have a high melting point
