“…However, in sample 2 and sample 3, most of chromium (about 9 and 18 wt% chromium added in the alloy) dissolves into Fe 2 B and chromium atoms replace the iron atoms, thus leading to the structural changes in borides, i.e. M 2 B, as mentioned in many investigations [13,14,17]. Moreover, from the Fe-Cr-B-C phase diagram, as proposed by Christodoulou [18], the boride is identified as M 2 B (M = Fe, Cr, etc.)…”

“…If the addition of chromium to Fe-B cast alloy can play the same role, the wear resistance of Fe-B cast alloy will increase. It has been reported that the addition of chromium has significant influence on the fracture toughness and hardness of boride [12,13]. Guo [14] has discovered that chromium can increase the solubility of boron in Fe-B cast alloy.…”

“…Estas variaciones podrían estar relacionadas con el porcentaje total de elementos de aleación en la matriz [19][20][21], lo que afectaría la formación de las nanoestructuras. No se observaron fases amorfas indicando que la solidificación tuvo lugar a una velocidad menor a la velocidad de enfriamiento crítica para la formación de vidrios metálicos, lo que produce una estructura de la matriz de α-Fe, de grano nanométrico.…”

“…Asimismo, se observaron carburos primarios alargados del tipo M 23 C 6 . Posteriormente el líquido remante se transformó en el eutéctico formado por γ-Fe o α-Fe y M 7 (BC) 3 [20]. La austenita fue observada sobre zonas segregadas, como se indica en la Figura 7a.…”

“…En el segundo, encontrado en las muestras con baja dilución (H3 y H5), precipitan inicialmente los NbC, y posteriormente, con la disminución de la temperatura, nuclean sobre ellos los carboboruros complejos M 23 X 6 , como se indica en la fi gura 9c; fi nalmente, a partir del líquido remanente se forma el eutéctico, M 7 X 3 y a-Fe [13][14][15], fi gura 9d. Este modo de solidifi cación fue encontrado en trabajos recientes [16,17] con el consumible en estudio, realizados en 1 y 2 capas, donde la dilución fue más baja.…”
