Calphad: Computer Coupling of Phase Diagrams and Thermochemistry | Year: 2012

The binary phase diagrams of the YCl 3-ACl (A=Li, Na, K, Rb, Cs) systems were studied using the CALPHAD technique and nonlinear mathematical method. The new modified quasi-chemical model in the pair-approximation for short-range ordering was applied to describe the Gibbs energies of the liquid phase in these systems. And the paper created the Artificial Neural Networks (ANN) model to study the interaction coefficients of two ending compounds composing the binary systems which are important for thermodynamic study of multi-elements system. Based on measured phase equilibrium data, a set of thermodynamic functions has been optimized and calculated. The effects of ionic radius, electronegativity and mole fraction of YCl 3 on interaction coefficients were investigated in more detail. © 2012 Elsevier Ltd. All rights reserved.

The authors prepared modified polypropylene (PP) by blending pure PP with reinforcing agent, toughener and grafted PP, and tested tensile strength and notched Charpy impact strength of the modified PP. A method specially devised by the authors-visual analysis-was applied to study the tensile strength. The optimal formula for producing the blend with the tensile strength over 80.0 MPa was determined, in which the mass fraction of the pure PP, reinforcing agent, toughener and grafted PP was set in the range of 62%-63%, 23.0%-30.0%, 5.0%-7.0% and 7.3%-8.0%, respectively.
