Cracking in High-strength Steel Weldments
Author: P. A. Kammer
Publisher:
ISBN:
Category : Steel
Languages : en
Pages : 132
Book Description
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 Numerous reports of investigations in this field are contained in the published and unpublished literature.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).

High-strength-steel Forgings
Author: H. J. Henning
Publisher:
ISBN:
Category : Blacksmithing
Languages : en
Pages : 68
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.

Status Report No. 2 on Department of Defense Refractory Metals Sheet-rolling Program
Author: H. R. Ogden
Publisher:
ISBN:
Category : Heat resistant alloys
Languages : en
Pages : 54
Book Description
The Nb program is nearing completion of laboratory tory rolling studiory materials, *Heat resistant alloys, *Sheets, Niobium alloys, Molybdenum alloys, Tantalum alloys, Tungsten alloys, Titanium alloys, Zirconium alloys, Tungsten, Powder metallurgy, Electric arcs, Manufacturing methods, Mechanical proper ies, Forging, Heat treatment, Melting, Extrusion, Deformation, Hardness, Rolling mills, Processing. Identifiers: Floturning. The Nb program is nearing completion of laboratory tory rolling studies, and a single composition for larger scale rolling studies will be selected in the near future. In the Mo program, it has been shown that true hot forging of billets to sheet bar results in higher recrystallization temperatures of TZM and Mo-0.5Ti sheet than are obtained when normal forging temperatures are used. The Ta program is in the early stages of ingot production and primary breakdown fabrication of the Ta-30Nb-7.5V alloy. Three methods of fabricating W sheet are being investigated: rolling of powder-metallurgy billets, fabrication of arc-melted ingots, and floturning of cylindrical blanks. Properties obtained on both powdermetallurgy and arc-melted tungsten sheet compare very favorably. Evaluation of the formability of Mo-alloy sheet has been delayed until sheet is available from the production program. (Author).
