Observing the dilatation changes and microstructure of castings from piston aluminium alloy

Popis výsledku v původním jazyce

This article deals with observing of coefficient thermal contraction and microstructure of piston aluminium alloy and influence of used casting moulds and various casting temperatures on them. This was done to make it possible to compare dilatation properties of alloys in components with microstructure of castings. Coefficients of thermal contraction were observed in aluminium alloys used for piston making of gas engines during solidification and cooling of castings from piston alloy AlSi12CuNiMg (eutectic, AW 48000). Castings were cast into the permanent and non-permanent moulds and the influence of mould material was observed. Materials of moulds were: Steel (permanent moulds), sand mixture with bentonite binder and sand mixture with water glass hardened by CO2 for non-permanent moulds (for simulation influence of cores on dilatation changes behavior). The conditions varied were also temperatures of casting and wall thickness of castings. Before cast melt was metallurgical treated by
