Abstract


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.
