Abstract
AbstractGrain-boundary relaxations have been studied, using a free-decay, internal-friction technique, in chromium-iron alloys containing 16 and 22.5% chromium. Values of δE, the relaxation strength, Q, the activation energy, and τ0, a pre-exponential factor, were calculated. The data are compared with previous results obtained by the author on other iron-chromium alloys, and the influence of σ phase formation on the relaxations is briefly assessed.
