摘      要：Stability and phase transformation of crystalline LaNi5-xAlx at temperature range of 298 to 873 K had been studied By x-ray diffraction pattern. It was found thatCrystalline LaNis-xAlx is a stable of crystal phase having CaCus-type structure only at the temperature range 298 to 773 K, But it exhibits an amorphous structure characterized as the segregation of Fcc-Ni phase at a temperature of 873 K.
