Abstract
Using Green's function method, an analytical, closed form solution for the problem of transient mass diffusion into a two-layer medium is found. Two p roblems are considered; composite slab and composite cylinder. Carbon diffu sion into slab composed of Ferrite steel and Austenite steel in perfect con tact is investigated. From the results, the time required for carbon concen tration to reach a certain level is estimated.
