The structure a.d therma. pa.a.eters of Ni20Pd80 a.loy were studied by X-ra. diffra.tion（XRD）. The diffra.tion experiments performed in the tempera.ure ra.ge of 308-1100 K revea.ed tha. the a.loy formed a.fa.e centered cubic （fcc） a.-type structure. The tempera.ure dependence of the la.tice pa.a.eters wa. investiga.ed by using the Bra.g line displa.ement method showing tha. the la.tice pa.a.eter increa.es with the increa.e of tempera.ure. The mea. linea. therma. expa.sion （MLTE（%））, coefficient of therma. expa.sion （CTE, α）, the cha.a.teristic Debye tempera.ure （（θD） a.d mea. squa.e a.plitudes of vibra.ion were determined from XRD da.a. The va.ue of Debye tempera.ure wa. found to be 253 K. It wa. found tha. tempera.ure fa.tor wa. independent of the sta.ic displa.ements.
