Available in PDF, EPUB and Kindle. Book excerpt: Nickel-free manganese-stabilized stainless steels are being developed for fusion reactor applications. As the first part of this effort, the austenite-stable region in the Fe-Mn-Cr-C system was determined. Results indicated that the Schaeffler diagram developed for Fe-Ni-Cr alloys cannot be used to predict the constituents expected for high manganese steels. This indicator is true because manganese is not as strong an austenite stabilizer relative to ?-ferrite formation as predicted by the diagram, but it is a stronger austenite stabilizer relative to martensite than predicted. Therefore, the austenite-stable region for Fe-Mn-Cr-C alloys occurs at lower chromium and higher combinations of manganese and carbon than predicted by the Schaeffler diagram. Development of a manganese-stabilized stainless steel should be possible in the composition range of 20 to 25% manganese, 10 to 15% chromium, and 0.1 to 0.25% carbon. Tensile behavior of an Fe-20%Mn-12%Cr-0.25%C alloy was determined. The strength and ductility of this possible base composition was comparable to Type 316 (UNS 531600) stainless steel in both the solution-annealed and cold-worked condition.

This book was released on 1990 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Special austenitic steels are being designed in which alloying elements like molybdenum, niobium, and nickel are replaced with manganese, tungsten, vanadium, titanium, and/or tantalum to reduce the long-term radioactivity induced by fusion reactor irradiation. However, the new steels still need to have properties otherwise similar to commercial steels like Type 316. Precipitation strongly affects strength and radiation-resistance in austenitic steels during irradiation at 400 to 600°C, and precipitation is also usually quite sensitive to alloy composition. The initial stage of development was to define a base Fe-Cr-Mn-C composition that formed stable austenite after annealing and cold-working, and resisted recovery or excessive formation of coarse carbide and intermetallic phases during elevated temperature annealing. These studies produced a Fe-12Cr-20Mn-0.25C base alloy. The next stage was to add the minor alloying elements titanium, vanadium, phosphorous, and boron for more strength and radiation-resistance. One of the goals was to produce fine MC precipitation behavior similar to the Ti-modified Fe-Cr-Ni prime candidate alloy (PCA). Additions of Ti + V + P + B produced fine MC precipitation along network dislocations and recovery/re-crystallization resistance in 20% cold-worked material aged at 800° for 168 h, whereas tungsten, titanium, W + Ti, or Ti + P + B additions did not. Addition of W +Ti + V + P + B also produced fine MC, but caused some ? phase formation and more recrystallization as well. These new alloys, therefore, achieved several of the initial design goals. Their fine MC precipitation and recovery/recrystallization behavior during aging is similar to that of the PCA. Calculations show that the new steels have over 103 times less long-term radioactivity than Type 316.

Available in PDF, EPUB and Kindle. Book excerpt: The need for alternate energy sources has led to the develop ment of prototype fusion and MHD reactors. Both possible energy systems in current designs usually require the use of magnetic fields for plasma confinement and concentration. For the creation and maintenance of large 5 to 15 tesla magnetic fields, supercon ducting magnets appear more economical. But the high magnetic fields create large forces, and the complexities of the conceptual reactors create severe space restrictions. The combination of re quirements, plus the desire to keep construction costs at a mini mum, has created a need for stronger structural alloys for service at liquid helium temperature (4 K). The complexity of the required structures requires that these alloys be weldable. Furthermore, since the plasma is influenced by magnetic fields and since magnet ic forces from the use of ferromagnetic materials in many configur ations may be additive, the best structural alloy for most applica tions should be nonmagnetic. These requirements have led to consideration of higher strength austenitic steels. Strength increases at low temperatures are achieved by the addition of nitrogen. The stability of the austenitic structure is retained by adding manganese instead of nickel, which is more expensive. Research to develop these higher strength austenitic steels is in process, primarily in Japan and the United States.

Available in PDF, EPUB and Kindle. Book excerpt: The third annual International Industrialization Symposium on the SuperCollider, IISSC-held March 13-15, 1991, in Atlanta, Ga.-was an enormous success. The number of attendees, exhibitors, and representatives from foreign countries surpassed the totals of previous years. There were 740 attendees, representing more than 2 dozen universities and colleges, 32 states, 9 national labs, 6 research centers, several government entities at the local, state, and federal level, 182 businesses & industry and 14 countries. More than 100 exhibits, sponsored by 85 organizations, added to the excitement. "Getting Down to Business" was the theme of this year's Symposium. The fact that the Superconducting SuperCollider (SSC) is indeed underway was the message delivered by the Symposium's keynote speaker, Dr. Roy Schwitters, and expanded upon by the opening plenary speakers. The project is moving from the planning stage to actual construction, to development and procurement of equipment, and to resolution of the technical issues involved in advancing the state-of-the-art in areas such as theory, controls, systems, metallurgy, quality control, management, cryogenics, power systems, detectors, interagency cooperation and funding.
