Which of the following makes a metal softer?
A - Purify the metal
B - Create Precipitates
D - Dislocation yield Strength
E - None of these
Homework Answers
Option E is correct
As they increase hardness in metals.
For making metals soft the process used is Annealing which is a form of heat treatment that brings a metal closer to its equilibrium state. It softens metal, making it more workable and providing for greater ductility. In this process, the metal is heated above its upper critical temperature to change its microstructure. Afterward, the metal is slow-cooled.
So none of option given are correct. So option E is correct.
