    THERMOTECH THERMOTECHNOLOGY GENERAL CATALOG Fusion of new technology and our extensive experience in heat treatment Fujikoshi's Thermotech Division has the heat treatment technology that supports the foundations of the world of manufacturing. In 1928, NACHI-FUJIKOSHI Corp. was founded to begin domestic production of cutting tools in Japan, starting by manufacturing hacksaw blades. In 1938, with the completion of its own steel mill, NACHI-FUJIKOSHI Corp. established full in-house production from materials to finished products. By capitalizing on techniques learned producing our own line of cutting tools, in 1961 we began production of salt-bath furnaces for heat treatment work. We then began developing our own technologies, and introducing some from overseas. Our production of industrial furnaces and auxiliary equipment was based on our vacuum heat treatment technologies, balancing the needs for heat treatment work with environmental impact. Welcome to a guide to NACHI-FUJIKOSHI Corp.'s multifaceted capabilities in processes for full in-house manufacturing from materials to finished product. Our aim is to support the needs of our customers with total service; from manufacturing and sales to maintenance and technical support; working to advance heat treatment technologies. 1 THERMOTECH DIVISION History 1961 Salt-bath furnace production started in-house 1963 Salt-bath furnaces sales started 1968 Introducing American technologies for atmosphere furnaces and aluminum furnaces 1974 Vacuum heat treatment furnace production and sales started 1981

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT DESIGN AND FABRICATION OF A HIGH-TEMPERATURE HIGH-VACUUM FURNACE TO HEAT TREAT NIOBIUM FOR SUPERCONDUCTING RADIO FREQUENCY CAVITIES By Saravan Kumar Chandrasekaran The noble metal niobium is increasingly used for the fabrication of superconducting radio frequency (SRF) cavities, which accelerate charged atomic and sub-atomic par- ticles to speeds between 5 and 100 % of the speed of light. The fabrication of SRF cavities typically involves large deformation of niobium sheet, introducing large strain in the metal. Strain produces dislocations in the metal, which is known to degrade the heat transfer properties of the metal. For improved thermal performance, annealing at 600 °C to 800 °C in vacuum can be done to stress relieve the deformed metal.
