New Materials for Next-Generation Commercial Transports
Author: Committee on New Materials for Advanced Civil AircraftPublisher: National Academies Press
ISBN: 0309588782
Category : Technology & Engineering
Languages : en
Pages : 99
Book Description
The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.

Book Description
THIS REPORT IS MAINLY CONCERNED WITH FORGINGS MADE FROM MARTENSITIC STEELS HEAT TREATED TO STRENGTHS RANGING FROM 240,000 TO 300,000 PSI. FORGING CHARACTERISTICS, DESIGN LIMITATIONS, DIMENSIONAL TOLERANCES, AND QUALITY-CONTROL PROBLEMS ARE DISCUSSED. A CONSIDERABLE AMOUNT OF DATA ON MECHANICAL PROPERTIES IS ALSO PRESENTED. IN ADDITION, THE REPORT SUMMARIZES THE AVAILABLE INFORMATION ON FORGED, SEMIAUSTENITIAL STEELS. THIS COMPILATION IS BASED ON PUBLISHED ARTICLES, GOVERNMENT REPORTS, AND INTERVIEWS WITH PRODUCERS AND USERS OF STEEL FORGINGS.
Methods of Strengthening the Ultrahigh-strength Steels

Book Description
Strengthening methods for ultrahigh- trength s e ls are describ a i cus ed. The objective is to provid the designer with an idea of t e prop rti s which can be developed by various proces es and th operating personnel with an outline of procedure The processes include the conventional quench and t per, martempering, Ausforming, prestrain a d r p r, pr cipitation hardening as it applies to special steel compositions designed for this purpose (i.e., mar gi g), and austempering. Included for each method is ou line of the proces bul ion of the chanical properties whic c n be expected, iscussion of ny limitations which the process may have, and if available, an explanation of the mech nis of strengthening.

ISBN:
Category : Steel
Languages : en
Pages : 52
Book Description
THE ACHIEVEMENT AND MAINTENANCE OF DESIRED DIMENSIONS IN COMPLEX, PRECISION-BUILT STRUCTURES, SUCH AS ROCKET-MOTOR CASES, ARE CRITICAL AND TECHNICALLY INVOLVED PROBLEMS. Their proper functioning demands close dimensional tolerances. Dimensional stability is extremely difficult toACHIEVE IN STEELS AT ULTRAHIGH STRENGTH LEVELS. The problem stems from interacting metallurgical factors which manifest themselves in volumetric and shape changes. The principal sources of size change are the changes in specific volume accompanying the phase transformations which occur in hardening and tempering. Distortion occurs when a part deforms in response to stress. The problem of dimensional instability is analyzed, the factors involved are discussed, and recommendations are made regarding the control of these factors. (Author).

Fracture Toughness of High-strength Steels for Military Applications
Author: J. E. CampbellPublisher:
ISBN:
Category : Steel, High strength
Languages : en
Pages : 22
Book Description
The Memorandum discusses the current situation on the inclusion of fracture-toughness testing requirements in specifications for high-strength steels used for military applications. The Memorandum was prepared at the request of The Technical Cooperation Program (TTCP), and contains information from Canadian and British members of that program, as well as U.S. information. Military applications discussed include missile motor cases, aircraft landing gear, gun tubes, armor plate, and hydrofoils. (Author).
