Abstract
A mathematical model is developed for the diffusion of hydrogen in steel on machining; this entails the solution of a second-order differential equation with variable coefficients. The initial and boundary conditions are determined. Numerical solution is based on the alternating-direction implicit method. The experimental temperature dependence of the effective diffusion coefficient for hydrogen is employed in modeling.
