Semi-continuous casting and microstructure investigation of the AlSi12 alloy

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Semi-continuously cast AlSi12 alloy was investigated by our research group at the University of Miskolc in the Institute of Physical Metallurgy, Metalforming and Nanotechnology under laboratory condition. Our goal was to define correlation and tendency between casting parameters and solidified microstructures. The examined alloy

Characterization of the Bonding Zone in AZ91/AlSi12 Bimetals Fabricated by Liquid-Solid Compound Casting Using Unmodified and Thermally Modified AlSi12 Alloy

Strojniški vestnik – Journal of Mechanical Engineering, 2020
Liquid-solid compound casting was used to produce two types of AZ91/AlSi12 joints. The magnesium alloy was the cast material poured onto a solid aluminium alloy insert with an unmodified or modified structure. The bonding zone obtained for the unmodified insert was not uniform in thickness. There was a eutectic region (Mg17Al12 + a solid solution of Al

Experimental and computational surface roughness analysis of aluminium silicon 12 (AlSi12) produced by powder bed fusion for transport applications [PDF]

MATEC Web of Conferences
Surface roughness influences the mechanical performance of a part. A rougher surface is prone to cracks and corrosion due to increased friction and harsh environments in transport applications.

Fabrication and Mechanical Properties of AlSi12 Nano Particulate Composite

Procedia Materials Science, 2015
AbstractNano-particulate composite AlSi12 with Single, Double and Multi walled Carbon Nanotubes (SWCNTs, DWCNTs & MWCNTs) as reinforcement at 0.5% by weight are fabricated using powder metallurgy process. Powder Metallurgy test specimens were prepared according to ASTM B-925 standards and specimens were tested for Tensile strength and Hardness.

Influence of Heat Treatment on Abrasive Wear Resistance of Silumin Matrix Composite Castings

Archives of Metallurgy and Materials, 2016
The authors attempted at examining the effect of heat treatment on abrasive wear resistance of metal composite castings. Metal matrix composites were made by infiltrating preforms created from unordered short fibers (graphite or silumin) with liquid ...
