Question 1: (Metallic Materials)
This is the process of growth of grain fragments in an alloy when it’s being worked on. This affects materials properties and services while in use.
Examples such as steel’s properties are affected such that there is reduction in strength and hardness of the material and this affects its applications and behavior in service. Other materials such as copper are affected in the same way.
Hot or cold working:
Hot or cold working involves hardening of materials and also and also heating the material. Iron is an example and is affected by hot working where it can be cast in Continue reading...
