| Abstract: | The isothermal transformation behaviour of the metallic glass Fe40Ni40P14B6 between 320 and 400° C is described. Crystallization occurs by a eutectic mechanism to form Fe-Ni austenite and a body-centred tetragonal phase which is isomorphous with Fe3P and Ni3P. The eutectic crystals have a barrel shape such that the c-axis of the tetragonal phase is parallel to the barrel axis. The orientation relationship between the two phases is  1 1 0 T  1 1 0 and 0 0 1T 1 1 2. The austenite phase contains (1 1 1) twins. |
