Abstract

Se realizó la simulación numérica de la evolución microestructural en aleaciones Cu-Ni-Fe, Cu-48%at.Ni-8%at.Fe y Cu-46%at.Ni-4%at.Fe envejecidas a 673, 723 y 773 K por diferentes tiempos. Se siguió la evolución microestructural utilizando MICE, MET y DRX para las aleaciones Cu-48%at.Ni-8%at.Fe y Cu- 46%at.Ni-4%at.Fe envejecidas a las mismas condiciones. Los resultados de simulación numérica mostraron una buena concordancia con los experimentales. La descomposición de fases ocurre en forma espinodal produciendo dos fases: rica en Cu-Ni y rica en Ni-Fe. La morfología y composición de las fasescoinciden con las observadas experimentalmente y/o reportadas en la literatura
