Abstract

In this work, the effect of pressure on the crystallization (T c ) and glass transition (T g ) temperatures of a modelled PdSi liquid alloy was investigated for different cooling rates by using Quantum Sutton Chen(K-SC) potential which is used to determine the interactions between atoms. It was determined that at the cooling rates of 2,5x10 11 K/s and 2,5x10 12 K/s the alloy system in liquid phase transformed into crystal and amorphous phase, respectively. The glass transition temperature was defined by the Wendt-Abraham parameter and radial distribution function (RDF) peaks. It was concluded that the increment of pressure led to an increase in the crystallization and glass transition temperatures and the ratio of T g /T m resulted in an improvement of the glass forming ability.
