Available in PDF, EPUB and Kindle. Book excerpt: The influence of in-process solution and solution and aging treatments on the properties of several molybdenum-base alloys is described. Alloys of molybdenum with titanium and/or zirconium were processed to bar stock by extrusion and rolling procedures. Extruded bars were prepared for rolling to final size either by heating to the minimum recrystallization temperature or by the application of optimum solution or solution and aging treatments. The latter procedures resulted in significantly higher recrystallization temperatures and tensile strengths than the procedure involving recrystallization prior to rolling. The high elevated temperature strengths obtained for the molybdenum-base alloys studied resulted from a critically dispersed carbide phase. A limited amount of work indicated that a dispersion hardenable molybdenum-beryllium alloy could be worked by extrusion. Room temperature hardnesses approaching 500 DPH were developed by the application of the proper solution and aging treatments to the extruded molybdenum-beryllium alloy. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The progress of work aimed at explaining the strengthening mechanisms operative in several molybdenum-base alloys is described. The optimum carbon contents for conventionally processed molybdenum-base alloys containing titanium, hafnium, zirconium, and titanium + zirconium are defined. The possibilities of increasing the strengths and reducing the optimum carbon content of these materials through solution and aging heat treatments are discussed. Attempts to prepare wrought sections of molybdenum-base alloys containing nominally 10% Cb and/or 10% Ta were only marginally successful owing to difficulties encountered in working the vacuumarc-cast ingots. A series of experiments is described wherein various melting and deoxidation practices are evaluated in connection with the 50% Mo-50% W alloy. Alloys based on tungsten or on various molybdenum-tungsten ratios have received considerable attention. Considerable difficulty was encountered in converting certain of the alloys of this type to bar stock. Outstanding elevated-temperature tensile and stressrupture properties are reported for a number of the compositions that were successfully converted to wrought stock. (Author).

Book Synopsis Mechanical Properties of Molybdenum And Molybdenum-Base Alloy Sheet by : Robert Q. Barr
Download or read book Mechanical Properties of Molybdenum And Molybdenum-Base Alloy Sheet written by Robert Q. Barr and published by . This book was released on 1960 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical and physical properties of molybdenum and molybdenum-base alloys have been rather extensively documented in the past decade. Almost all of these data have been developed in connection with investigations of wrought bar stock; very little data have been accumulated on the properties of sheet. On the other hand, considerable interest has developed in recent years in the utilization of molybdenum and molybdenum-base alloys in the form of sheet products. This interest is concentrated on sheet of about 1/16-in. gage. This paper represents a summary of the several investigations that were initiated to determine some of the mechanical properties of unalloyed molybdenum and of three molybdenum-base alloys, processed to 1/16 in. thick sheet from vacuum arc-cast ingots.

Available in PDF, EPUB and Kindle. Book excerpt: A number of complex molybdenum-, molybdenumtungsten-, and tungsten-base alloys were consolidated by the vacuum-arc-casting technique. Successful extrusions were realized from all of the vacuum-arc-cast ingots. Extrusion constants well above those of earlier experiments were measured, indicative of the good elevated-temperature strength and concomitant high resistance to extrusion of the materials studied. Rolled bars were studied from the standpoint of recrystallization behavior, transition temperature, tensile properties as a function of temperature and, to a limited extent, creep-rupture properties. A carbon synergism was studied in the alloys Mo + 3% Ti + 0.5% Zr and Mo + 25% W + 1.25% Ti + 0.1% Zr from the standpoint of elevated temperature strength. In the case of both alloys, the carbon contents yielding the highest elevated temperature strengths also resulted in the highest transition temperatures as measured by the tensile test. An alloy based on Mo-50% W, and containing 0.8% Ti and 0.3% Zr, displayed exceptionally high strengths at elevated temperatures. The tensile transition temperature of this material was, however, above room temperature. (Author).
