The diffusion induced stress leads to bending of thin unconstrained diffusion couples. The observation of the temporal evolution of the sample bending radius can be used to follow the generation and relaxation of stresses, once the underlying process is fully understood. With this aim a detailed theoretical study of the diffusional bending was undertaken. Computer simulation and analytic calculations were combined in the theoretical analysis. Both unconstrained - bending - and constrained -massive- diffusion couples were investigated. Experimental results in Ti-Zr sheets are compared with the theoretical findings.
