摘要: Glass forming abilities of a ternary Y-Co-Si system were determined on the basis combined semi-empirical Miedema's and geometric models. The enthalpy amorphous solid solution phases formation, along with mismatch entropy GFA parameter, analysed to indicate compositions highest ability for amorphization. large atomic radii di erence between constituents, especially Y Si, is deciding factor GFA. Compositions ranged Y33Si67 Y45Si55 are best glass formers. DOI: 10.12693/APhysPolA.126.62 PACS: 05.70.-a, 61.43.Dq, 81.30.Bx
