QUÉ SIGNIFICA PRECIPITATION HARDENING EN INGLÉS
Endurecimiento por precipitación
El endurecimiento por precipitación, también llamado endurecimiento por edades, es una técnica de tratamiento térmico que se usa para aumentar el límite de elasticidad de los materiales maleables, incluyendo la mayoría de aleaciones estructurales de aluminio, magnesio, níquel, titanio y algunos aceros inoxidables. En superaleaciones, se sabe que causa una anomalía de elasticidad que proporciona una excelente resistencia a altas temperaturas. El endurecimiento por precipitación se basa en cambios en la solubilidad de los sólidos con la temperatura para producir partículas finas de una fase de impureza, lo que impide el movimiento de dislocaciones o defectos en la red cristalina. Puesto que las dislocaciones son a menudo los portadores dominantes de la plasticidad, esto sirve para endurecer el material. Las impurezas desempeñan el mismo papel que las sustancias de partículas en materiales compuestos reforzados con partículas. Así como la formación de hielo en el aire puede producir nubes, nieve o granizo, dependiendo del historial térmico de una parte dada de la atmósfera, la precipitación en sólidos puede producir muchos tamaños diferentes de partículas que tienen propiedades radicalmente diferentes. A diferencia del revenido ordinario, las aleaciones deben mantenerse a temperatura elevada durante horas para permitir la precipitación. Este retardo de tiempo se denomina "envejecimiento".
definición de precipitation hardening en el diccionario inglés
La definición de endurecimiento por precipitación en el diccionario es un proceso en el que las aleaciones se fortalecen mediante la formación, en su retícula, de una fina dispersión de un componente cuando el metal se apaga desde una temperatura alta y envejece a una temperatura intermedia.
