Abstract

Celem pracy jest analiza mikro i makronaprężeń w spiekach i kompozytach otrzymanych pod wysokim ciśnieniem i wysoką temperaturą. Wartości mikronaprężeń są obliczane z wykorzystaneim plotów Williamsona-Halla. Ocena makronaprężeń przeprowadzana jest na podstawie zmiany położenia lini dyfrakcyjnych. W prezenatcji zostanie pokazane jak zmianiaja się mikronaprężenia tego samego materiału w spieku i kompozycie, a także zmianę wartości mikro i makronaprężeń wraz ze zmianą warunków otrzymania spieków i kompozytów. Przedstawiona zostanie także część teoratyczna, wyjaśniająca dlaczego "widzimy" mikro i makronaprężenai na dyfraktogramie.
