RECENT PROGRESS OF THE SPring-8 FACILITY
Since October 1997, the SPring-8 facility has been operated well and provided high quality photon beams for users. Over this period, various kinds of improvements have been carried out to achieve brilliant and stable photon beams and to make the most of 8-GeV potentiality. At the same time R&D has continued for future radiation sources. In these activities, the largest achievement has been the ...
متن کاملEffects of Temperature and Oxygen Concentration on the Characteristics of Decarburization of 55SiCr Spring Steel
Effects of temperature and oxygen concentration on decarburization of 55SiCr spring steel were investigated at the temperature range of 500°C–1 200°C by using a Muffle furnace (an atmosphere of ambient air) and a Simultaneous Thermal Analyzer (low oxygen concentration with 2% O2 and 98% N2). In ambient air, the decarburization behavior can be divided roughly into five temperature ranges: T≥1 20...
