Eutectic Fe-C, Ni-C and Fe-C-Si alloys have been solidified
directionally in an electron-beam floating zone apparatus under carefully
controlled conditions and the resulting morphologies in these alloy
systems have been studied as a function of rate. In addition, the
transition from the stable iron-graphite (grey iron) to the metastable
iron-iron carbide (white iron) mode has been observed and has been
related to the iron-carbon/iron-iron carbide double phase diagram by
means of undercooling measurements. Interlamellar spacing measurements
carried out on both the graphitic and carbidic modes using material of
the same composition and purity under identical experimental conditions
showed a λaR-1/2 and a λaR-1/3 relationship in the iron-graphite and
iron-iron carbide eutectic systems, respectively. / Thesis / Doctor of Philosophy (PhD)
