Title Validation of predicted residual stresses within DC cast WE43 slab
Abstract During direct chill (DC) casting of the high strength magnesium alloy, Elektron WE43, a significant level of cold cracking has been observed. These cracks have been attributed to the formation of significant residual stresses during casting. A finite element modeling (FEM) code, called ALSIM, has been used to predict the residual stress within the DC cast slab. Validation of FEM simulations were carried out using neutron diffraction measurements of the residual stress field within a 870 x 315 mm sized slab. Given that measurements in such large scale components using diffraction measurements are particularly challenging and expensive, efficient use of neutron diffraction measurements is emphasized. This has included the use of sectioning methods to map the residual stresses in detail, allowing validation of the predicted stresses.
