Katsutoshi Ono, Ryosuke O. Suzuki


Journal of the Mass Spectrometry Society of Japan, 47, [1], pp.38-41, 1999.


Born of necessity in the metallurgy of the reactive metals, vacuum technology is now being applied to the steel-making resulting in excellent quality control and properties not otherwise realizable. To provide an insight into the selection and evaluation of the experimental data, the authors have considered it advisable to present a systematic review of the principles and theories on evaporation phenomena. This article containes the basic aspect of the free evaporation under perfect vacuum, the vapor transfer through the thermal boundary layer under poor vacuum, the enhancement of evaporation, the restriction evaporation and the selective evaporation from multi-component bulk.
