Which risk increases significantly as temperature cycles drive stress within a polycrystalline metal lattice?

💡 Explanation

Cycling temperatures cause repeated expansion and contraction in grain boundaries, initializing creep void nucleation; because of coefficient differences. This stress aggregation leads to material failure, rather than enhanced electron mobility or corrosion resistance at these boundaries; therefore promoting voids.
