Download or read book Low-Temperature Properties of Cold-Rolled AISI Types 301, 302, 304ELC, and 310 Stainless Steel Sheet written by James F. Watson and published by . This book was released on 1961 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cold-rolled austenitic stainless steels have assumed an important position in missile and space vehicle applications where they are used as skins and other highly stressed structural members at temperatures ranging down to -423 F (the boiling point of hydrogen). The critical nature of structural weight and pressure integrity in pressurized cryogenic propellant tanks in this application requires a material having an optimum combination of high strength-density ratio, weldability, and resistance to brittle fracture at cryogenic temperatures, as well as adequate formability and corrosion resistance. The AISI type 300 series austenitic stainless steels are used for this type of application because of their excellent weldability and toughness at low temperature and their moderately high strength-density ratios which improve markedly at lower temperatures. In this investigation, the mechanical properties of a series of cold-rolled austenitic stainless steels were determined at 78, -100, -320, and -423 F. The alloys were studied in a variety of cold-worked tempers in thicknesses varying between 0.013 and 0.032 in. These alloys were subjected to tension tests in both smooth and notched (stress concentration factor, Kt = 6.3) configurations to provide values of yield and tensile strength, elongation, notched-unnotched tensile ratios in the base metal, and tensile strength and elongation in heliarc butt welded joints. The notched tension tests were included in this study to evaluate toughness which is a measure of resistance to brittle failure. Toughness is a property of vital importance in missile design because these missile structures are subject to shock-type loads which occur during hydraulic hammering, vibration due to rocket engine firing, and action of quick closing valves, and will contain built-in stress concentrations of varying degrees of intensity due to welding defects, tool marks, assembly eccentricities, and random defects in the metal. These conditions all favor brittle failure, and become even more severe at low temperature in that brittle fracture is more prone to occur at reduced temperatures.

This book was released on 1963 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various aspects of the physical metallurgy of the 18 % nickel maraging steels are discussed in this report in the light of the knowledge which has thus far been accumulated on these steels. The 18 % nickel type of maraging steel was singled out for discussion because of its especially attractive combination of strength and fracture toughness, the comparative simplicity with which it can be hardened, and the relative ease with which it can be formed and joined. The highnickel maraging steels are considered to be outstanding members of a loose-knit family of agehardenable or precipitation-hardenable martensitic steels. Some comparisons and analogies are drawn among various members of this family with particular reference to the 18% nickel steels. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A detailed picture is presented of the physical and chemical phenomena that affect the behavior of cobalt-base superalloys. Solid-solution strengthening is obtained from the high-melting metallic elements molybdenum, tungsten, tantalum, and columbium. These elements also participate in precipitation reactions involving their carbides. Precipitation of intermetallic compounds such as Ni3Ti is an important process in cobalt alloys containing appreciable amounts of nickel and titanium. The relationships among microstructure, heat treatment, and mechanical properties of the important commercial alloys are considered, and whenever possible, explained on the basis of the physical and chem cal processes that occur.

Available in PDF, EPUB and Kindle. Book excerpt: On October 3, 1963, a symposium was sponsored by the Bureau of Naval Weapons, Metalworking Processes and Equipment Program, on the application of high pressure in metal-deformation processing. Past research has shown that superimposed hydrostatic pressure can significantly increase the ductility at fracture of various materials. These observations have stimulated considerable interest in applying this hydrostatic-pressure effect to metal deformation processing, where it was anticipated that improved ductility and fabricability of brittle materials could be realized. Hydrostatic extrusion and hydrodynamic compressive forging were two such fabrication techniques discussed at the symposium, and preliminary results were found to be encouraging. Another fabrication process that will be investigated in the near future is sheet drawing, where the effect of superimposed pressure improves the ductility to fracture, it was noted that pressure cycling did not improve either the strength or ductility of steels containing various amounts of carbon. In addition to the mechanical-property effects, hydrostatic pressure has been found to affect measurably, numerous metallurgical properties of metals and alloys. (Author).

Included with each binary diagram and with some ternary diagrams is a short discussion listing terminal solubilities and crystal struc tures of intermediate pahses. Many of the diagrams are tentative and are subject to revision as additional data become available. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes information on refractory composites for use above 2500 F, as presented at the Seventh Meeting of the Refractory Composites Working Group, held March 12-14, 1963. Reports presented at the meeting were concerned with pro tective coatings, insulating ceramics, materials for rocket thrust chambers, dispersion strength ening of metals, joining of refractory materials, and testing techniques. Emphasis in the field of coatings for refractory metals has shifted from the rudiments of developing oxidation-resistant coatings to improvement and advanced evaluation of coatings to predict their utility for re-entry vehicles.
