Objectif The prime objective is to develop realistic and fundamentally sound quantitative models of the relationships between process variables and solidification. Realistic and fundamentally sound quantitative models of the relationships between process variables and solidification structure for conditions of rapid solidification have been developed. Results obtained include:first ever results for spacing of primary silicon as a function of solidification variables in hypereutectic aluminium silicon alloys;development of a numerical model of single cell growth that shows that steady state solutions exist for dendrites only if some anistropy stabilises the tip;measured critical velocities for formation of alpha aluminium dendrites in laser surface traversed hypereutectic aluminium silicon in good agreement with predictions of competitive growth modelling;measurements of atomizing gas velocity versus position in a spray chamber in excellent agreement with published data;development of a numerical model of spray droplet cooling and solidification in good agreement with experimental results for copper-6% by weight tin;predictions of time and position dependence of temperature and state within a growing spray deposit.
