Hot tear is one of the most serious defect which a casting can suffer. It represents a major limitation to the production of foundry cast parts and to the productivity of continuous casting processes such as the direct chiil casting of aluminium alloys. As ...
Microsegregation in a binary alloy solidified in the form of deep cells is predicted using a simplified finite difference model. The model accounts for solid state diffusion and for flow of liquid between cells driven by solidification shrinkage. Cell tip ...
The tolerances of semi-continuously cast products of aluminium alloys are very critical if the scalping of the ingot faces is to be minimised before rolling. In the steady state regime of casting, the dimensions of the section of the solidified ingot are l ...
As for most of the topics in the field of solidification, Mert Flemings has always pioneered new ideas. While much of the understanding of hot tearing formation was already known about 30 years ago, he devised with Metz an interesting apparatus for studyin ...
The mechanical properties of continuous fibre reinforced metals (CFRMs) are known to be very sensitive to the selection and composition of the metallic matrix; for aluminium based CFRMs, commercial alloys are not suitable for this purpose. In the present s ...
In many casting processes, some stages, such as the starting phase in the direct chill casting of aluminium alloys, are particularly critical because of the propensity of some alloys to develop either hot tears which initiate at non zero liquid fraction, o ...

A comprehensive three-dimensional mathematical model based upon the Abaqus software has been developed for the computation of the thermomechanical state of the solidifying strand during direct chill (DC) casting of rolling sheet ingots and during subsequen ...
The prediction of the ingot deformation during direct chiil (DC) and electromagnetic (EM) casting of aluminum alloy slabs would allow the optimization of the moldlinductor shape capable of producing flat ingots. The transient thermomechanical model present ...
