O. Jin et Bx. Liu, HEXAGONAL-CLOSE-PACKED FACE-CENTERED-CUBIC TRANSFORMATION IN IRRADIATED HAFNIUM THIN-FILMS, Materials letters, 27(4-5), 1996, pp. 165-169
Hafnium thin films, 45 nm thick were investigated by transmission elec
tron microscopy and were shown to deposit with a hexagonal close packe
d structure, then transformed to a face centered cubic structure after
being irradiated by 200 keV xenon ions at room temperature.
