THE USE OF FAST ELECTRONS IN METALLOGRAPHIC INVESTIGATIONS,
Abstract
Ionization and mixing of atoms during electron bombardment may affect phase transformations in alloys containing phases with intermediate properties, ionic bonds, or metastable bonds. It is shown that the joint radiative-thermal effect, including the heating during irradiation, leads to a phase transformation in white iron. The disintegrating cementite is replaced by ferrite with spheroidal graphite. It is assumed that, in the processes being studied the function of the nonlocal warmup under an electron beam is the same as that of local bursts of heat during neutron irradiation, and that this function is reduced to acceleration of the diffusion processes.
