摘要：

This study concerns a hitherto unknown bcc --> fcc allotropic transformation in Nb induced by the mechanical alloying of Nb80Al20. This metastable transformation is preceded by a gradual increase in the lattice parameter of bcc-Nb. The stored excess energy in nanocrystalline bcc-Nb may be responsible for the bcc --> fcc phase transition. (C) 1999 American Institute of Physics. [S0021-8979(99)03622-1].
