Determining the Interphase Boundary Parameters in Heterogeneous Binary Alloys on the Basis of the Hypothesis of Weak Nonlocality
Based on our earlier hypothesis of weak nonlocality, we developed a method for calculating the temperature dependences of the width and specific energy of the interphase boundary for binary substitutional alloys, using the concentration dependence of the internal energy or the equilibrium phase diag...

| description | Based on our earlier hypothesis of weak nonlocality, we developed a method for calculating the temperature dependences of the width and specific energy of the interphase boundary for binary substitutional alloys, using the concentration dependence of the internal energy or the equilibrium phase diagram of the alloy. Numerically calculated temperature dependences of the solubility limits, specific energy, and thickness of the interphase boundary are presented for three thermodynamic models: the regular solution model (Nb–Cu alloy), the quasi-regular solution model, and the general case (Fe–Cu alloy and A–B alloy that differs from Fe–Cu in the sign of excess entropy). |
