Xg. Li et al., PREPARATION OF FINE NB3AL POWDER BY HYDRIDING AND DEHYDRIDING OF BULKMATERIAL, Journal of alloys and compounds, 227(2), 1995, pp. 141-144
Structural changes of the intermetallic compound Nb3Al before and afte
r hydriding and dehydriding have been investigated by X-ray diffractio
n, electron microscopy and thermal analysis. A fine powder of this com
pound with an average particle size less than 14 mu m can be easily pr
epared by hydriding at 773 K for 86.4 x 10(3) s and dehydriding at 107
3 K for 10.8 x 10(3) s.
