Prediction of the Occurrence of a Phase in Austenitic Matrix of Ni-base Superalloys Using Thermodynamic Equilibria Calculation倪克铨,陈国良,朱平,夏海萍摘 要:<正> Using the calculation of thermodynamicequilibria in multicomponent systems,two ternaryphase diagrams,Ni-Cr-Mo and Ni-Cr-Co,havebeen calculated by optimizing the Gibbs free ener-gies with respect......
) Abstract:The freckle formation and their phase characterizatics in freckle areas were investigated by means of microstructure analysis approaches and a thermodynamic equilibrium phase calculation... and liquid segregation calculation can give a reasonable interpretation of the freckle feature for this alloy. Key words:freckle; superalloy; Inconel 625; thermodynamic calculation; [全文内容正在添加中] ......
through thermogravimetric (TG) and differential scanning calorimetry (DSC), and the TG-DSC analysis confirmed the results of thermodynamic calculation. The results show that the ability of metal sulfate decomposition can be ordered as follows (from easy to difficult): FeSO4, In2(SO4)3, Fe2(SO4)3, ZnSO4, PbSO4. The phase transition and decomposition temperatures from thermodynamic calculation......
, and the tensile elongation is increased by 43% after electroslag refining. The chemical reaction between melt and slag to form Fe2B is the main reason for iron reduction and the thermodynamic calculation of the chemical reaction theoretically accounts for the formation of Fe2B. Key words: aluminum; electroslag refining; iron; mechanical properties; thermodynamic calculation 1 Introduction Iron is considered......

A thermodynamic model setting pressure of 50 MPa (Pf=Ps=50 MPa) was set up to trace the skarn evolution. Petrographic evidence for replacement......
of electronic structures, but also agree well with corresponding experimental data in the literature. Key words: ZrC; phase transition; thermodynamic properties; elastic properties; first principles calculation... model and thermal electronic excitation were combined with ab initio calculation to obtain various thermodynamic and mechanical properties of ZrC as a function of temperature and pressure. 2......
