Abstract

Un cuerpo sinterizado compuesto contiene partículas de nitruro de boro cúbico y partículas de aglutinante. El cuerpo sinterizado compuesto contiene 40% en volumen o más y 80% en volumen o menos de las partículas de nitruro de boro cúbico. Las partículas de aglutinante contienen partículas de TiCN. El cuerpo sinterizado compuesto muestra un primer pico que pertenece a un plano (200) de las partículas de TiCN en un intervalo en el cual un ángulo de Bragg 2? es 41.7° o más y 42.6° o menos en un espectro de difracción de rayos X medido utilizando un rayo Cu-Ka como una fuente de rayo. Asumiendo que un eje vertical y en el espectro de difracción de rayos X indica la intensidad de difracción, y que un valor máximo de una altura pico del primer pico se define como Imáx, una diferencia entre un valor máximo y un valor mínimo de los ángulos de Bragg 2? es 0.4° o menos, los ángulos de Bragg 2? que se miden en dos o más puntos de intersección de una línea recta y = Imáx/2 y el primer pico.
