Which consequence results when a geothermal power plant turbine superheats?

💡 Explanation

Superheating causes creep deformation via vacancy diffusion, because thermal energy overcomes atomic attractions. Therefore, long-term strength dramatically decreases due to grain boundary sliding, rather than increasing fracture resistance or lowering component fatigue.
