Abstract

Microstructure-dependent stress-free lattice spacings (d₀) were measured using neutron diffraction in a comb-like specimen fabricated from a quenched carbon steel cylinder. The d₀ values increased with cylinder radius due to the increase in the martensite (α') fraction with the radius and were comparable to d₀ values calculated using the lattice parameter of each phase, taking the auto-tempering effect into consideration. Using the measured d₀ values, we suggested a relationship between the d₀ and α' fraction and evaluated macroscopic residual stresses in the quenched steel cylinder.
