The development in the study of iron and steel in Japan during the year 1946∿55 has been surveyed in this article. First, subjects of study has been reviewed, then detailed description has been made under the several major headings, classified by the author. The use of semicaking coal produced in Hokkaido has been successfully used for blast furnace works and several other problems, such as the desulphurization of pig iron, elimination of copper from pyrite cinder, pelletizing as well as the pre-treatment of raw materials have been among the problems concerned in the field of iron making. The utilization of pyrite cinder, pyrrohotite, magnetite sand, laterite and other minerals containing iron which has not yet been utilized as an iron ore has been considered. Heat-treatment has been studied by many workers and the application of S-curve, repeated tempering procedure, sub-zero of deep cooling treatment and stepped quenching have been the chief subjects studied. None the less research works have been made in the field of physical chemistry of iron and steel making ; and the measurement of activity in steel making reactions, study on the equillibrium in the reduction of iron oxide, activity measurement of the elements coexisting in molten iron and the study on the mutual relationships between each stages in open hearth operation have carried out. Besides this, many valuable research results have been published, for example ; on white spot problem, behavior of gases, heat-resisting steels, theoretical and practical study of working, boron steel and the measurement of hardenability by Jominy test, use of oxygen in steel making, quality control and process control, development of some new methods of research work and vacuum melting technology. As the reconstruction from the war disaster was not complete during the earlier years, few important study work was carried out before 1949. The developments made in this decade can be said to be striking, but it is a pity of the author that only a few purely original study has been found.
