Q.  
At room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all ______ with ______ grain size.


Answer & Explanation

At room temperature, as grain size decreases, hardness, yield strength, tensile strength, fatigue strength, and impact strength generally increase. Finer grains improve the mechanical properties of the material.

Thus correct option is: B.
