Investigation in structure and mechanical properties of a356 alloy with micro 100 agent additions

Popis výsledku v původním jazyce

In recent years, aluminium alloys are still important because of their low density and good technological properties, together with good mechanical and corrosion properties. Various processes such as rolling, extrusion and powder metallurgy are available for production of an aluminium alloy component, but foundry processes play an important role. When casting these alloys, we often encounter internal defects, such as shrinkage and bubbles, which are the main factors affecting the quality of the casting. The requirements for casting quality are constantly increasing, so the aim is to eliminate these defects to the smallest possible amount and size. For this reason, current foundries are forced to guarantee the highest possible quality of castings. Deposits in aluminium alloys are produced mainly in castings with unfavourable wall thickness or in places of heat knots, which cannot be cast, for example, due to unsuitable casting construction. The shrinkage has a negative impact on the mechanical properties and pressure-tightness of the castings produced. Probat Fluss Micro100 helps improve the quality of castings. To evaluate the porosity, experiments were performed using light microscopy and EDX analysis. To confirm these results, a static tensile experiment was performed to confirm an increase in the strength values of the castings of these alloys after the use of Micro 100. Based on the results of the analyses, the optimum amount of these agents having the greatest effect on the A356 alloy was determined.
