Based on the graphs of stress-strain from the V-MSE site, how would you characterize the general differences between polymers and alloys in terms of mechanical properties?

a. Alloys are stronger, stiffer, but less ductile.

b. Polymers have a higher toughness.

c. Alloys have lower Young's Modulus.

d. The properties overlap so you can't really make any general statements.

Option A

Explanation:

Alloys are metal compounds with two or more metals or non metals to create new compounds that exhibit superior structural properties. Alloys have high level of hardness that resists deformation thereby making it less ductile compared to polymers. This is due to the varying difference in the chemical and physical characteristics of the constituent metals in the alloy.
