Abstract Effects of pressure and temperature on grain size of nanocrystalline α-Fe(Mo,Si) produced by annealing amorphous (Fe_(0.99)Mo_(0.01)_(78)Si_9B_(13) alloys in temperature range from 723 to 933 K under pressures range of 3 to 6 GPa were studied. It is found that the effect of pressure on α-Fe(Mo,Si) grain size results mainly from nucleation rate, and its basic cause is the effect on melting point. Yet the effect of pressure, decreasing growth rate, on the fomiation temperature and critical pressure of smallest grain size of α-Fe(Mo,Si) can be negligible.
