← TechnologyWhich consequence results when forging connecting rods without proper quenching?
A)Increased susceptibility to hydrogen embrittlement
B)Elevated residual tensile stress develops✓
C)Enhanced resistance to fatigue cracking
D)Improved dimensional stability at temperature
💡 Explanation
Elevated residual tensile stress develops because the uneven cooling lacks martensite formation afforded by proper quenching during forging; therefore, tensile stress remains, rather than compressive stress improving component performance.
