Book excerpt: Weldment cracking is a broad complex field. Even if one considers only cracking of steel weldments, the problems range from cracking at temperatures near the solidus during welding to cracking at room temperature days, weeks, or months after welding is completed. Numerous reports of investigations in this field are contained in the published and unpublished literature. However, most of these reports cover only a particular problem in a specific area of the broad field of weldment cracking. This review attempts to cover the major aspects of the entire field of weldment cracking. Necessarily, the review is for the most part general, only being specific in a few instances to illustrate a point. (Author).

Download or read book Semiaustenitic Precipitation-hardenable Stainless Steels written by D. C. Ludwigson and published by . This book was released on 1961 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semiaustenitic precipitation-hardenable stainless steels remain austenitic on cooling rom a solution heat treatment at about 1950 F. In this form they are readily fabricable. Subsequent treatment at about 1400 or at about 1725 F depletes the austenite of Cr and C to the extent that martensite forms on cooling to room temperature or -100 F, respectively. Final hardening is effected by tempering, or aging, at 750 to 1100 F. The semiaustenitic precipitation-hardenable stainless steels may be obtained as transformed at the mill by cold rolling. In this condition they lack the good formability of solution-heat-treated material. However, the fabricator need only temper them to obtain very high strengths. These steels have a combination of good formability, high strength, and excellent corrosion resistance that is not easily matched by other materials.

Download or read book Vacuum Degassing in the Production of Premium-quality Steels written by P. J. O'Reilly and published by . This book was released on 1964 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report gives the experiences of several steel producers and consumers with vacuum degassing as a melting practice in the manufacture of high-strength steels for critical applications. The parameters involved in determining the effects of melting practice on mechanical properties are outlined. Pertinent melting processes are described and evaluated qualitatively. In presenting the data, vacuum degassing is compared with other melting practices such as conventional air melting and consumable-electrode vacuum-arc remelting (CEVAR). Generally, there is a trend indicating that vacuum degassing is being used in some production applications instead of air-melted or CEVAR material. In terms of higher and more uniform transverse tensile properties and impact strength, longer fatigue life, and improved cleanliness, the CEVAR alloys were the best. Vacuum degassing by any of the various methods resulted in an improvement in properties of air-melted alloys. In some instances it appeared that the quality of CEVAR alloys could be approached when stream degassing or D-H (Dortmund-Horder) treatment was applied to air melts. Recommendations are given for additional investigations on the effects of melting practice on mechanical properties of premium-quality steels. (Author).

Download or read book The Mechanical Properties of the 18 Per Cent Nickel Maraging Steels written by J. E. Campbell and published by . This book was released on 1964 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the combination of tensile properties and toughness that can be obtained with the maraging steels is higher than can be achieved with other steels by simple heat treatments, there is considerable interest in using the maraging steels for critical components such as rocket motor cases, pressure vessels, and aircraft forgings. This report includes information on the tensile, compressive, shear, bearing, dynamic modulus, impact, bend, fatigue, creep, and rupture properties of the 18 per cent nickel maraging steels and on the effect of temperature on these properties. Data for the properties of sheet, bar, and forgings, as well as data illustrating the effect of cold rolling, variation in the heat treatment, and elevated-temperature exposure also are presented. Data on the effect of specimen orientation, which are also included, indicate that the ductility and toughness of specimens designed to evaluate the properties in the short transverse direction are somewhat lower than in the other directions. The high strength and toughness that can be obtained in the 18 per cent nickel maraging steels make them attractive for certain critical applications that require these properties. The fabrication characteristics, weldability, and simple heat treatment are other advantages of these steels. (Author).

Book excerpt: This report supplements DMIC Report 152 which is a compilation of binary and ternary phase diagrams of columbium, molybdenum, tantalum, and tungsten. Forty new binary and 80 new ternary diagrams are included, some of these being revised versions of the previously published diagrams. 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).

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.
