Abstract

Método para la fabricación de componentes forjados de una aleación de TiAl, especialmente álabes de turbinas, en el que los componentes son forjados y después del forjado se someten a un tratamiento térmico de dos etapas, y la primera etapa del tratamiento térmico comprende un recocido de recristalización durante 50 hasta 100 minutos a una temperatura por debajo de la temperatura de transformación γ/α, es decir, en el ámbito de temperatura entre 1300ºC hasta 900ºC, especialmente, temperatura de enfriamiento de recristalización entre 1200ºC hasta 1300ºC y la segunda etapa del tratamiento térmico comprende un recocido de estabilización en el ámbito de temperatura de 800ºC hasta 950ºC por 5 hasta 7 h., y se utiliza una aleación de TiAl con 42 hasta 45% en átomos de aluminio, 3 hasta 5% en átomos de niobio, y 0,5 hasta 1,5% en átomos de molibdeno, que se caracteriza por que la velocidad de enfriamiento en la primera etapa de tratamiento térmico es mayor o igual a 3ºC, para ajustar una estructura de láminas finas de α2-Ti3Al y γ-TiAl en una correspondiente fase α2 y fase γ.
