Thermal processing and thermal analysis of AlSi12–SiC hybrid composites sintered
Journal of Thermal Analysis and Calorimetry, 2019Metal powders are used in industry for a diversity of products and applications. Metal matrix composites are materials developed through advanced methods with increased characteristics that surpass those of conventional materials. In recent years, the aluminum alloy matrix composites (AlSiX/graphite, AlSiMg/SiC, Al/SiC) are considered better substitute

Preparation and properties of foamable Ni-GNP/AlSi12 Precursor Materials
Kastamonu University Journal of Engineering and SciencesIn this study, nickel-coated graphene nanoplatelets reinforced AlSi12 precursor materials were produced by powder metallurgy method. For this process, Ni-GNP particles were added to the matrix material AlSi12 powders at different ratios (0%, 0.4%, 0.8% and 1.2% by weight).

The Production and Subsequent Selective Laser Melting of AlSi12 Powder
Solid State Phenomena, 2017The paper studies the atomization of Al-based alloy AlSi12 in gas jet. Air was used as a spraying gas. The size and shape of powder particles were studied by using scanning electron microscopy and optical granulomorphometer. The obtained powder was used in selective laser melting.

An Artificial Neural Network Approach to Predict the Properties of AlSi12 Alloy
SSRN Electronic Journal, 2009The effects of modification and vibration during solidification of Aluminum-Silicon eutectic alloy (AlSi12) are studied and compared with unmodified alloy. Sodium and Strontium are used as modifiers. Horizontal sinusoidal vibration at different frequencies was imposed using a vibration table. It was found that modification treatment improves properties

Mechanical properties of electron-beam-melted AlSi12 surface layers
Journal of Materials Science, 1990The melting parameters for an AlSi12 alloy, which lead to surface-melted layers with constant melting depth and smooth surface have been discovered using the electron beam melting technique. The main mechanical properties of the melted layer were determined with different testing methods, which were adapted for this specific use.

Characterization of AlSi12 alloy
2018Powder material is an important parameter in powder-based additive manufacturing which can affect the quality of the manufactured parts significantly. Therefore, fresh as well as recycled powder material was analyzed under scanning electron microscope to view the size, the morphology and the chemical composition.

Impact of modification and wall thickness on the properties of AlSi12 alloy
2021The effect of sodium and strontium modification and the wall thickness on solidification, microstructure and mechanical properties of eutectic AlSi12 alloy were analysed. Modification of eutectic (αAl+βSi) leads to transformation of eutectic βSi phase morphology, from coarse lamellar to fine fibrous, in order to improve mechanical properties.

Thermographic analysis of AlSi12 during crystallisation as a function of cooling rate
International Journal of Materials Research, 2009Abstract At the Institute of Materials Science of the Leibniz University of Hannover, investigations were carried out to better understand the crystallisation processes of the cast alloy AlSi12. Here, the influence of different cooling rates was investigated in-situ and ex-situ. The temperatures of the geometric specimens were determined

Laser welding of ALSI12 and S355 with a 10 kW single mode fiber laser
ICALEO 2018: 37th International Congress on Applications of Lasers & Electro-Optics, 2018In this study, fast welding of an aluminum alloy AlSi12 and a structural steel S355 was investigated using a single mode fiber laser system delivering a maximum laser power of 10 kW with a laser beam quality of M² = 2. The laser beam was focused with a welding head OL YW50 F500 HQ from Precitec GmbH & Co.
