Download or read book New Developments in Welding Steels with Yield Strengths Greater Than 150,000 PSI written by Robert Melvin Evans and published by . This book was released on 1965 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes the advancements made in the development and welding of steels possessing yield strengths greater than 150,000 psi. Steels discussed include the medium carbon, low-alloy martensitic steels; low carbon alloy martensites; and nickel maraging steels. Almost all programs which have the objective of developing high-strength steels have an equally important phase concerned with filler metal development. Filler metals are also discussed. The new welding processes discussed are Narrow-Gap welding, electron-beam welding, plasma-arc welding, high-frequency resistance welding, electroslag welding, laser welding, and interrupted-arc (dip trasfer) MIG welding.

Book Synopsis Recent Developments in Welding Thick Titanium Plate by : R. E. Monroe
Download or read book Recent Developments in Welding Thick Titanium Plate written by R. E. Monroe and published by . This book was released on 1965 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum represents a combined effort by the U.S. Naval Applied Science Laboratory, Brooklyn, New York, and the Defense Metals Information Center to summarize new information on welding thick Ti plate. Thick plate of Ti continues to be of interest to the aerospace and defense industries for possible use in submersibles, armored vehicles, large space boosters, high-speed aircraft, and for pressure vessels. This memorandum generally is limited to information on welding Ti plate that is (1) at least 1 in. thick and (2) that is not covered by DMIC Report 185, The Status and Properties of Titanium Alloys for Thick Plate, June 14, 1963. The general requirements for welding Ti are not repeated here, since they are well documented in references mentioned in the inroduction to the memorandum. Sections have been prepared to cover material developments, welding-process developments, weld properties, and residual welding stresses. (Author).
Book Synopsis Consideration of Steels with Over 150,000 Psi Yield Strength for Deep-submergence Hulls by : G. K. Manning
Download or read book Consideration of Steels with Over 150,000 Psi Yield Strength for Deep-submergence Hulls written by G. K. Manning and published by . This book was released on 1963 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three types of ferrous materials that deserve to be considered as future hull materials are discussed. The present state of knowledge can be summarized this way: quenched and tempered steels with 0.20% carbon and yield strengths of about 170,000 psi can probably be developed into a useful hull material in less time than either of the other two classes. Maraging steels have great potential if it is possible to improve their toughness. This may be resolved within a few months and surely within a year. The stable austenitic steels appear to offer the greatest potential, but less is known about these than about the other two classes of materials. (Author).
Book Synopsis Welding High-strength Steels by : P. A. Kammer
Download or read book Welding High-strength Steels written by P. A. Kammer and published by . This book was released on 1966 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of the developments in welding steels with yield strengths greater than 150 ksi have included low-alloy martensitic steels, medium-alloy martensitic steels, nickel maraging steels, and bainitic steels. Only weldments from medium-alloy martensitic steels and nickel maraging steels have mechanical properties approaching those of the base plate without a complete postweld heat treatment. The most serious problem with the other steel is low toughness in the weld fusion zone. Adequate weld metal toughness under conditions of elastic strain can be obtarined over the entire 150 to 225 ksi yield-strength range only if the tungsten-arc welding process is used. Processes with higher deposition rates can produce comparable weld deposits only in the lower portion of the range. Above a yield strength of 200 ksi, 18Ni maraging steel weldments have the best combination of strength and toughness. Below 200 ksi, the HP 9-4-25 medium-alloy martensitic steel and 12Ni maraging steel weldments have nearly equal properties.

Book Synopsis The 9Ni-4Co Steels by : T. P. Groeneveld
Download or read book The 9Ni-4Co Steels written by T. P. Groeneveld and published by . This book was released on 1966 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum briefly discusses the physical metallurgy, heat treatment, mechanical properties, stress-corrosion properties, and fabrication of the 9Ni-4Co-XC steels. This family of steels was developed specifically to meet the requirements of the aircraft and aerospace industries for materials possessing high strength and high toughness. By varying the composition and heat treatment, the 9Ni-4Co-xC steels can develop strengths in the 200 to 300 ksi tensile-strength range and reportedly possess high toughness. The lower carbon grades have excellent weldability, developing strength in the 180 to 200 ksi range with high toughness without the need for preheat or postweld-heat treatment. (Author).
Book Synopsis Weldability of High-strength Aluminum Alloys by : Robert Melvin Evans
Download or read book Weldability of High-strength Aluminum Alloys written by Robert Melvin Evans and published by . This book was released on 1966 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum describes the fusion-welding characteristics, mechanical properties, and stress-corrosion behavior of high-strength, weldable aluminum alloys. These are defined as alloys in which sound welds can be produced and in which at least 50 and 70 percent of the maximum base-metal strength can be retained in the as-welded and post-weld-treated conditions, respectively. Careful selection of joining method and filler metals as well as close control of joining-process parameters is necessary to produce high-strength aluminum weldments. Highest strengths and weld-joint efficiencies in high-strength weldable alloys are achieved with the use of postweld aging and/or mechanical treatments. The best combination of highest strengths and good welding characteristics is found in the 2000 and 7000 alloy series. As compared with the 2000 and 5000 alloy series, the 7000 alloy as a class suffer three major property disadvantages: (1) their tendency to be notch sensitive, (2) their tendency to exhibit low toughness at low temperatures, and (3) their much greater susceptibility to stress-corrosion cracking. Nonetheless, several relatively new 7000 series alloys have been developed which show reasonably good notch toughness to -423 F and which are considered competitive with the 2219 and 2014 alloys for cryogenic applications.
