Özet

In recent years, several mechanisms have been suggested to explain the formation of fine grains during grain refinement process. All conducted studies indicate that TiB2 and Al3Ti particles create nucleus zones in molten metal. Offering an exact explanation for the grain refinement mechanism was purposed by using Electron Probe Micro Analysis (EPMA) technique for a comprehensive investigation of grain boundaries in terms of elemental distribution. In this study, DIN 226 high pressure die casting (HPDC) aluminum alloy was employed as the matrix system. 0.2%, 0.4% and 0.6% AlTi5B1 (by wt.) which is a common grain refiner master alloy was added to the smelting charge and samples were taken with different durations. Hardness and grain size tests were preformed on these samples.
