← ScienceWhich outcome follows prolonged mechanical stress above yield strength within polycrystalline alloy?
A)Accelerated creep rate and total failure✓
B)Enhanced corrosion resistance forms passively
C)Increased resilience at the atomic junctions
D)Decreased dislocation mobility within the matrix
💡 Explanation
Creep accelerates drastically leading to total failure because dislocation climb is exacerbated; this is a thermally activated process. The increase in grain boundary sliding elevates vacancy diffusion, therefore the lifespan reduces, rather than other mechanisms reducing material failures.
