Mechanical properties of electron-beam-melted AlSi12 surface layers

Journal of Materials Science, 1990
The 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.

Effect of Pore Characteristics of Si Preforms on the Infiltration Flow Behavior by AlSi12 Alloys

Materials Science
Si preforms with different particle sizes (20, 50 and 90 μ m) and starch contents (10 vol%, 20 vol% and 30 vol%) were fabricated by compression molding and heat treatment. A high resolution (1 μ m)

On the influence of process interruptions during additive manufacturing on the fatigue resistance of AlSi12

Additive Manufacturing, 2021
Abstract The process of laser-based powder bed fusion of metals (PBF-LB/M) is one of the most promising technologies in the field of additive manufacturing. The high freedom of design enables the integration of functionality and production of customized parts. Main drawbacks of this technology are related to relatively low build rates and reliability.

Characterization of AlSi12 alloy

2018
Powder 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.

Thermographic analysis of AlSi12 during crystallisation as a function of cooling rate

International Journal of Materials Research, 2009
Abstract 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

Impact of modification and wall thickness on the properties of AlSi12 alloy

2021
The 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.

An Artificial Neural Network Approach to Predict the Properties of AlSi12 Alloy

SSRN Electronic Journal, 2009
The 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

Analysis of the machining characteristics in reaming AlSi12 alloy with PCD reamer

The International Journal of Advanced Manufacturing Technology, 2013
Machining characteristics were studied for the reaming AlSi12 alloy using six flutes polycrystalline diamond reamer on DMG DMU 50 linear five-axis CNC machine. The output measures for this experiment comprise of cutting torque, cutting thrust, hole diameter, hole cylindricity, and workpiece surface finishing.
