John Grandfield has 25 years experience in light metal production and processing research in industry and government laboratories, including at Rio Tinto Alcan, CASTcrc and CSIRO, particularly in aluminium, magnesium continuous casting and metal refining. He has conducted technology reviews, optimized existing technology, managed technology transfer, and developed and commercialized new technology. Dr Grandfield is particularly experienced in direct chill (DC) casting including optimizing casting conditions for a variety of products including magnesium alloys. His doctorate thesis was on the hot-tearing of magnesium alloys during horizontal DC casting. Dr. Grandfield is the co-inventor of AirCAST, a new patented, gas pressurized, hot top DC mold for aluminium and magnesium. He has also been involved in twin roll casting of magnesium. Dr. Grandfield recently established Grandfield Technology Pty. Ltd., a technology consulting firm. He holds four patents and has published more than 50 conference and journal papers. Dr. Grandfield is chair of the Australasian Aluminium Casthouse Technology Conference. He earned his doctorate in materials science at the University of Queensland.

Dag Mortensen has been working on mathematical modeling with the finite element method (FEM) on casting processes for more than 20 years. His major activities have been on the mathematical modeling of the direct chill (DC) casting process of extrusion ingots and sheet ingots. Currently Mr. Mortensen is section head of Materials Processing at the Institute for Energy Technology in Norway. With co-workers, he has produced about 30 international publications in addition to restricted reports. Topics included heat- and fluid flow-modeling, grain growth during solidification, hot-tearing, direct water cooling and thermo-mechanical coupled boundary conditions during casting as well as secondary precipitation and microsegregation development during heat treatment. The mathematical models made by Mr. Mortensen and co-workers apply an in-house developed, finite element package. He has a precise knowledge of the code and of various applications of FEM methods and applied mathematics.
