Development Processes

Selecting an aluminum die casting alloy for a particular application often poses a challenge to designers and engineers. It is often difficult and sometimes not possible to find an alloy that meets all the requirements of the application; and in other times the alloy can be found, but it has a wide specified compositional range, and thus it exhibits a large variation in properties. Therefore, there is always a need to optimize existing alloys or to develop new alloys so that they meet the requirements of a given application. In order to help with the alloy selection and alloy development processes, we developed an electronic database for aluminum die casting alloys – i-Select-Al. This software can help its user to quickly select an alloy for a specific application from a comprehensive list of commercial alloys. Alternatively, it can help its user with the design of a new alloy to meet the requirements of the application. This paper presents a study in optimizing A380 alloy with the help of i-Select-Al. A380 alloy is the most commonly used die casting alloy, but it has a wide compositional range and therefore a wide range of properties. In this study, we optimized the mechanical properties of A380 alloy by optimizing its chemical composition. The Quality Index was used to quantify the changes in the alloys’ properties in response to changes in chemical composition. Two alloys were designed: one has a composition within the A380 alloy specification, and the other has a composition slightly outside the A380 alloy specification. Both alloys showed significant improvements in room temperature tensile properties and a substantial increase in the Quality Index over a commercially available A380 alloy.

Abstract This data set presents aging response curves for a wide range of aluminum casting alloys. The aging response curves are of two types: room-temperature, or "natural," curves and artificial, or "high-temperature," curves. The curves in each group are presented in the numeric sequence of the casting alloy designation. The curves included are the results of measurements on individual lots considered representative of the respective alloys and tempers. The properties considered are yield strength, ultimate tensile strength, elongation, and Brinell hardness.

Aluminium Casting Alloy

Abstract Issues connected with high quality casting alloys are important for responsible construction elements working in hard conditions. Traditionally, the quality of aluminium casting alloy refers to such microstructure properties as the presence of inclusions and intermetallic phases or porosity. At present, in most cases, Quality index refers to the level of mechanical properties – especially strength parameters, e.g.: UTS, YS, HB, E (Young’s Modulus), K1c (stress intensity factor). Quality indexes are often presented as a function of density. However, generally it is known, that operating durability of construction elements depends both on the strength and plastic of the material. Therefore, for several years now, in specialist literature, the concept of quality index (QI) was present, combines these two important qualities of construction material. The work presents the results of QI research for casting hypoeutectic silumin type EN AC-42100 (EN AC-AlSi7Mg0.3), depending on different variants of heat treatment, including jet cooling during solution treatment.

Aluminum Silicon

Aluminum-Silicon (Al-Si) alloys are one of the most widely used aluminum alloys. But iron can severely deteriorate the mechanical property of Al-Si diecasting alloy because its presence leads to the precipitation of different AlFeSi intermetallic phases which damage the ductility of alloys. Thus controlling the fraction and morphology of AlFeSi phase, especially the β-AlFeSi phase is important way to refine the ductility of Al-Si die casting alloys. In this article, K element was added into A380 alloys to study the effect of K on the morphology change of AlFeSi phase. The results show that a certain level of K addition 0.05-0.1 wt% will refine β-AlFeSi and transform β-AlFeSi phase to α-AlFeSi. In addition, K addition can better refine AlFeSi at high ccoling rates. The mechanism of refinement of K on AlFeSi phase is analyzed.
