Structure simulation of transition metalhyphen;metalloid glasss

摘要

Procedures are efficient numerical simulation.of multicomponent alloy glasses, using the concept of dense random packed (DRP) hard spheres, are described in detail. Methods of statistical analysis are discussed and applied to several simulated structures of transitionhyphen;metal (TM) ndash;metalloid (M) glasses. The pair correlations in DRP models using the conventional approach are found to be highly anisotropic and are concluded to be the cause of the varying density in these structures. Statistical data appropriate to Fehyphen;P and Pdhyphen;Si glasses are analyzed and discussed for the compositional range from TM73M27to Tm100. Certain structural features appear only near the 80/20 (atomic percentages) composition common to numerous stable glasses.
