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.

This book was released on 2013-11-21 with total page 1085 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Since 1954 Advances in Cryogenic Engineering has been the archival publication of papers presented at the biennial CEC/ICMC conferences. Advances in Cryogenic Engineering resides throughout the world in the libraries of most institutions that conduct research and development in cryogenic engineering and applied superconductivity. The publication includes invited, unsolicited, and government-sponsored research papers in the research areas of superconductors and structural materials for cryogenic applications. All of the papers published must (1) be presented at the conference, (2) pass the review process, and (3) report previously unpublished theoretical studies, reviews, or measurements of material properties at low temperatures."

Download or read book Control of Cryogenic Intergranular Fracture in High-manganese Austenitic Steels written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The sources of cryogenic intergranular embrittlement in high-Mn austenitic steels and the conditions necessary for its control are examined. It is shown that the high-Mn alloys are inherently susceptible to intergranular embrittlement due to both their low grain boundary cohesion and heterogeneous deformation characteristics. Extrinsic sources of embrittlement which could account for the transition behavior are not observed. An Auger electron spectroscopy (AES) study shows no indication of impurity-segregation-induced embrittlement. No grain boundary precipitation is observed, and austenite stabilization does not ensure ductile fracture. The influence of chemistry modifications on the ductile-to-brittle transition behavior were also examined through additions of N, Cr, and C to binary Fe-31 Mn. Nitrogen additions increase the 77K yield strength at a rate of 2200 MPa per weight percent N, and increase the austenite stability, but also increase the susceptibility of ternary alloys to intergranular fracture. Quaternary Cr additions are effective in increasing the N solubility, and lower the transition temperature. Carbon additions result in complete suppression of intergranular fracture at 77K. Qualitatively significant changes in the deformation heterogeneity with chemistry modifications are not observed. The temper-toughening of Fe-Mn-Cr-N alloys is associated with the grain boundary segregation of boron and the redistribution of N. Both boron and carbon are expected to inhibit intergranular fracture through increases in grain boundary cohesion.

Download or read book Design of an Fe--12Mn--0. 2Ti Alloy Steel for Low Temperature Use written by and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-0.2 Ti alloy steels. A two-phase (a + .gamma.) tempering in combination with cold-working or hot-working has been identified as an effective treatment. In an Fe-12 Mn-0.2 Ti alloy a promising combination of fracture toughness and yield strength was obtained at -196°C. A potential application as a Ni-free cryogenic steel was thus shown for this alloy. These improvements of properties were mainly attributed to the ultra-fine grain size and to a uniform distribution of retained austenite. It was also shown that an Fe-8 Mn steel could be grain-refined by a purely thermal treatment because of its dislocated martensitic structure and absence of epsilon phase. As a result, a significant reduction of the ductile-brittle transition temperature was obtained in this alloy. The nature and origin of brittle fracture in Fe-Mn alloys were also investigated. Two embrittling regions were found in a cooling curve of an Fe-12 Mn-0.2 Ti steel which were shown to be responsible for intergranular fracture. A fast cooling through the martensite transformation temperatures results in a quench-crack type brittleness along prior .gamma. grain boundaries. Auger electron spectroscopy identified no segregation during solution-annealing treatment. If held too long below the transformation finish temperature, the 12 Mn steel undergoes another form of embrittlement. This phenomenon was attributed to intergranular tempered martensite embrittlement. Avoiding the embrittling zones by controlled cooling led to a high cryogenic toughness in a solution-annealed condition.
