Q1 At elevated working temperature the metal working is less

Q1: At elevated working temperature, the metal working is less sensitive to the strain rate applied. (True or False)

Q2: At room temperature, the metal working is more sensitive to the strain rate applied? (True or False)

Solution

>> At elevated Temperature, the internal atoms in the material are moving fast. So, working is easy now. So, Strain rate won\'t have much effect on metal working or in other words, metal working is less sensitive to Strain rate applied.

So, Statement 1 is TRUE

>> at room temperature, the energy of atoms is not more and so to make working easy, Strain is applied

So, this statement is TRUE
