Abstract
A Fortran program is described for calculating and plotting time-temperature-crystallization curves during rapid heating and cooling by, for example, laser glazing, electron beam melting, melt-spinning or other techniques for the production of metallic glasses and metastable phases. Experiments were carried out to demonstrate the applicability of the program. In the case of Fe-B alloys produced by melt-spinning the behaviour during continuous cooling and isothermal annealing could be predicted. In the case of Ni-Nb alloys the program was used to establish the experimental conditions for the formation of metallic glass by electron beam melting. The program was also used to determine the conditions necessary for glass formation by laser melting a surface layer of boron alloyed to the surface of an Fe-Cr substrate.
