Question

Effect of grain size on mechanical properties of metals

Answer 1

Grain size has a measurable effect on most mechanical properties. For exam- ple, at room temperature, hardness, yield strength, tensilestrength, fatigue strength and impactstrength all increase with decreasinggrain size. ... Thus, for example, yield stress is more dependent on grain size than ten- sile strength 

Answer 2

Answer:

Explain the effect of Grain size on the properties of metals.
