Which outcome occurs when residual stresses exceed tensile strength?

💡 Explanation

Workpiece distortion happens because residual stresses in the casting induce plastic deformation, exceeding tensile capabilities where stress relief treatments were insufficient after, therefore, distortion occurs rather than maintained shape due to compressive stress.
