An investigation has been made on the relation between half value breadth (H. V. B.) and hardness of quenched-tempered steels. The following results have been obtained. (1) There are some good correlations between H. V. B. and hardness of quenched-tempered steels. These correlations are classified by the carbon content of steels and are well worth taking advantage for engineering use. (2) The change in H. V. B. is not influenced by precipitation hardening though it is remarkably affected by solid solution hardening and dislocation density. However. the change in hardness is not so remarkable as that in H. V. B. with dislocation density. (3) The result of tensile test revealed that H. V. B. having a value over 4.0 degree in 2θ decreases with plastic strain until the strain reaches at a certain value before it began to increase with strain, though H. V. B. under 4.0 degree increases monotonously with strain from the initial state.
