SELECTION OF OPTIMAL CONDITIONS FOR SOLID BONDING OF THE AlSi11 ALUMINIUM ALLOY

Abstract

1Effect of rapid solidification aluminum alloys with different Si contents on mechanical properties and microstructureWpływ szybkiej krystalizacji stopów aluminium z różną zawartością Si na własności mechaniczne oraz mikrostrukturę AbstractRapid solidification is a relatively new and effective way of producing ultrafine-grained UFG aluminum alloys with enhanced mechanical properties. Due to a significant cooling rate close to nearly 10 6 K/s, it is possible to obtain a material with grain size far below 100 nm. In the present study, RS aluminum alloys with an Si content in a range of 5-10 wt% were produced during melt spinning. As a result, materials in the form of ribbons were produced. The as-received flakes were subjected to cold pressing into cylindrical billets with a diameter of 40 mm. Hot extrusion of pre-compacted material was subsequently performed at a temperature of 450°C with a press ram speed of 3 mm/s and extrusion ratio of λ = 25. In this work, the influence of brittle phases on the mechanical properties of as-extruded rods will be examined. Both tensile and microhardness tests were performed in order to determine the mechanical properties of the obtained profiles. It has been shown that brittle-phase refinement during melt spinning significantly influences the mechanical properties of the tested materials.

Design and Development of a Portable Metal Chip Baler using A System Design Approach

“…These processes produce metal waste by removing the unwanted metal on the workpiece and the type of metal waste that are produced are metal chips. Some industries have taken a good initiative to overcome those issues where it gives benefit to the industries as well in terms of end-of-life profit by recycling the metal chips [4]. In order to recycle the metal chips, a larger space is needed to store these metal chips before the metal chips can be recycled.…”
