Presence of defects such as vacancies in a crystal enhances its A. Stability B. Durability C. Elasticity D. Compatibility

The shear modulus of a material is always considerably smaller than the Young modulus for it. Whatdoes it signify?

a super saturated solution is not stable in the presence of crystals of solid. Why?

hoose the statement which is TRUEQuestion 1Answera.A higher number of dislocations in a given material will lead to a decrease in modulusb.Work hardening results in materials becoming more brittlec.The work hardening rate is a material property that describes the optimum rate of elongation to efficiently produce dislocationsd.Dislocations always repel each other
