Question

Match the heat treatment processes (Group A) and their associated effects on properties (Group B) of medium carbon steel Group A Group B P: Tempering I: Strengthening and grain refinement Q: Quenching II: Inducing toughness R: Annealing III: Hardening S: Normalizing IV: Softening

Group A	Group B
P: Tempering	I: Strengthening and grain refinement
Q: Quenching	II: Inducing toughness
R: Annealing	III: Hardening
S: Normalizing	IV: Softening

Correct answer (B) P-II, Q-III, R-IV, S-I Solution The correct matching is: Tempering (P) : Induces toughness and reduces brittleness (II). Quenching (Q) : Increases hardness by rapid cooling (III). Annealing (R) : Softens the material to improve machinability and ductility (IV). Normalizing (S) : Refines the grain structure and improves strength (I). Thus, the correct sequence is P-II, Q-III, R-IV, S-I. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
