The purpose of this paper is to develop a mathematical equation, which will be able to accurately predict the liquidus temperature of various aluminum and magnesium cast alloys on the basis of their known chemical compositions. This type of system could be used to calculate several thermo-physical and solidification process parameters of multicomponent aluminum alloys in either cast or melt treated conditions. The analytical expressions presented in this paper are based on the “method of equivalency.” According to this concept, the influence of any alloying element on the liquidus temperature of an aluminum and/or magnesium alloy can be translated into the equivalent influence of a reference element. According to the available literature data, the accuracy of the applied thermal analysis technique was between ±0.5 and 1°C. solidus temperature. The AZ91 alloy (contains about 9 wt.% Al and 1 wt.% Zn) is the most widely used magnesium alloy exhibiting a good combination of high strength at room temperature, good castability, and excellent corrosion resistance. The accuracy of the calculated liquidus temperature in the proposed model (6a) and (6b) is dependent solely on the accuracy of the coefficients, by means of which the corresponding alloy content is converted into an equivalent silicon/aluminum weight percent. An accurate knowledge of liquidus temperature permits a researcher to predict a variety of physical parameters pertaining to a given alloy. The solubility of silicon in the aluminum melt reaches a maximum of 1.6 wt.% at the 577°C eutectic temperature. The melting temperature of pure aluminum is 660°C. Another advantage of a new equivalency method can be recognized in its general application to calculate the liquidus temperatures of other alloys. In lightweight magnesium alloys, aluminum is the mainly alloying element, chiefly because of its low price, availability, low density, and the advantageous effects on corrosion and strength properties. The solubility of magnesium in the aluminum melt reaches a maximum of 18.9 at.% at the 450°C eutectic temperature. The primary grains were characterized by image analysis which showed that the average grain size in two dimensions was ∼44 μm and the average circularity factor was ∼18, indicating that the grains were both fine and globular. The main advantage of the method of equivalency has been recognized in its simplicity and straightforward application. Manganese reduces the liquidus temperature by –23°C, leading to T l … The use of magnesium alloys has become significant due to a one-third lower density of magnesium compared with aluminum, improved damping ability, a higher resistance to corrosion and better mechanical properties.
