Sažetak
The piston is one of the main parts of an internal-combustion engine. As the material for piston design Al-Si alloys are mostly used, although the materials like gray iron, ceramics, composites etc. are also used. The aluminum alloy pistons are usually made by gravity or pressure casting technology. For this work the piston from aluminum alloy AlSi12CuNiMg was cast. The cooling rate was measured on three various position of the piston. The specimens were taken out from each position and metallographic research was conducted. Also the hardness testing was done. The specimens were subjected to heat treatment with purpose of microstructure homogenization. The obtained results have shown the microstructure differences, as also the hardness differences. The additional heat treatment had homogenized the microstructure with the marginal hardness decrease.
