N2 - TEM investigations on crystallization behavior of a Fe68C 10.5Si4.4B6.5P8.6Al2 bulk metallic glass reveals that the nano-scale fcc Fe phase formed by primary crystallization is homogeneously embedded in the amorphous matrix after heat treatment at 783 K for 30 min. With increasing heat treatment time (783 K for 45 min), a tetragonal Fe3(C,B,P) phase encapsulates the primary fcc Fe phase suppressing the growth of the fcc Fe phase. The Fe3(C,B,P) phase decomposes into a mixture of orthorhombic Fe3(C,P) and tetragonal Fe3(B,P) upon further annealing treatment at 783K.
