“…Indeed, an orientation relationship between the Laves phase and some crystalline phases exists, such as in the case of Cu-rich precipitates. It has been suggested that Cu-rich precipitates act as a nucleation site due to the setting of a high-coherence interface between the matching planes, like the case of austenite and Mo-rich BCC precipitate (as shown in table 3) with the C14 polytype [36][37][38]. Li Peng et al [39] have identified an orientation relationship between the C15 polytype and the BCC matrix in Crbased alloys, and the mismatch between planes (equation ( 15)) depends on the chromium content in the alloy for a linear behavior of the thermal expansion coefficient (in both phases).…”

“…Adicionalmente, también se identificó una fase FCC (CuMn) aislada debido a la diferencia en la entalpía de mezcla con el resto de los elementos químicos que componen la aleación. La estructura FCC (CuMn) permitió la precipitación preferencial de fase Laves y γ'' presumiblemente por la disminución de la energía interfacial y el aumento de la fuerza impulsora de ambos precipitados en esta solución sólida por el Cu como se ha reportado en diversas investigaciones previas [405][406][407][408][409][410]. Finalmente, la aleación presentó una fase σ resultante de la descomposición de la fase B2 a bajas temperaturas.…”
