Question

Consider the concept of elastic modulus at the atomic level and the inclusion of impurity in a metal alloy. What will be the influence of this impurity on the modulus of elasticity of this metallic material?
an. The modulus of elasticity becomes the same as that of the inserted impurity.
B. The modulus of elasticity of the metal locations.
c. The modulus of elasticity of the metal remains the same.
d. Metal loses its elastic properties

e. The modulus of elasticity of the metal increases, regardless of whether it is in smaller or larger proportions.

Expert Solution

Step 1

Elastic modulus or modulus of elasticity is the property of the material and is given as the ratio of normal stress to longitudinal strain.
Now as per the given condition if the impurities are added to a metal alloy, it depends on the impurities that are added to the alloy.
If the impurities contain less modulus of elasticity it decreases the elasticity of metal alloy as well and if it contains more elasticity it increases the elasticity of alloy.
