Magnesium alloys, LPSO phase, Synchrotron radiation diffraction, Thermal expansion coefficientAbstract
El coeficiente lineal de expansión térmica de la fase LPSO con estructura cristalográfica 18R se determinó en el intervalo entre temperatura ambiente y 400 °C mediante dilatometría y difracción de radiación sincrotrón. Los resultados muestran claramente que el coeficiente lineal de dilatación térmica de las fases magnesio y LPSO son similares y, por tanto, no se generan tensiones térmicas en su intercara durante el procesado termomecánico de aleaciones bifásicas Mg-Y-Zn.
