New approaches to casting hypereutectic Al-Si alloys to achieve simultaneous refinement of primary silicon and modification of eutectic silicon
Hypereutectic Al-Si alloys are of increasing interest for applications that require a combination of light weight and high wear resistance, such as pistons, liner-less engine blocks and pumps. The wear resistance of this class of alloys is due to the presence of hard primary Si particles formed …

An ultrasonic study of impurity-interstitial complexes in electron irradiated Al-Si and Al-Ag
… were performed to probe the structure and annealing behavior of solute self interstitial complexes in electron irradiated (T < 70 K) dilute Al-Ag and Al-Si alloys. In both alloy systems, a similar attenuation peak structure is observed. This peak structure strongly suggests that in both alloys, …

Instationäre Erstarrung eutektischer Al-Si-Legierungen
Solidification research has supplied an increasing contribution in the understanding of the relation between process-based solidification parameters (e.g. velocity, temperature gradient) and microstructure parameters in cast alloys (e.g. lamella distance, dendrite spacing). This is due to the …

Development of Niobium Boron grain retainer for aluminium silicon alloys
Aluminium castings with a large grain structure have poor mechanical properties which are primarily due to casting defects as opposed to fine grain structure. The grain refinement practice using chemical addition is well established for wrought alloys, however in the case of casting alloys, the …

Micromechanistic analysis of fatigue in aluminium silicon casting alloys
Due to increasingly stringent environmental legislation, there is a requirement for lower emissions and greater overall efficiency of light vehicle diesel (LVD) engines. This continues to be achieved through the optimisation of design and careful selection of the materials used in key LVD engine …

Control of morphology Al-Fe-Si phase in Al-Si-Cu hypoeutectic alloy
<p>Aluminum-Silicon (Al-Si) alloys are one of the most versatile aluminum alloys. Iron is considered one of the most harmful elements in Al-Si diecasting alloy because its presence leads to the precipitation of many AlFeSi intermetallic phases and unacceptable mechanical properties, such as …
