Abstract
The residual stress in aluminium-coated steel has been measured by using the equation described in our previous paper. The materials used were annealed mild steel sheets 0.2 mm thick. The successive uniform layers of material were removed chemically from the surface of a test specimen in order to introduce no further residual stress in the remaining material during removal. The following results were obtained. (1) Within the limit of our experiments, the effect of dipping temperature on the residual stress distribution is more perceptible than that of the dipping time. (2) The stress in the Al-layer derived from dipping process varies toward the compression side while its magnitude increases progressively with increasing dipping time and temperature. (3) The stress in the Fe-layer varies from the compression to the tension side with increasing dipping time and temperature. (4) At above 750° of the dipping temperature, the stress in Fe-layer and Al-layer showed tension and compression respectively.
