This book was released on 1960 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial heat-treatment studies are reported in which the effects of quenching rate upon room temperature ductility of iron-aluminum alloys were investigated. Quenching media included bciling water, oil at room temperature, and oil at 100 deg C. Experimental results are tabulated. No definite trends in tensile properties were observed with differences in quenching rate. Electropolishing techniques for use in preparation of specimens are discussed in relation to determination of microcrack effects on tensile tests. (For preceding period see AECU-4528.) (J.R.D.).

This book was released on 1961 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies are being made on the effects of variation of aluminum content, heat treatment, surface preparation, and other metallurgical factors on the room temperature ductility of Al-- Fe alloys. The variation of Fe3Al order as a function of temperature for 13.9 Alfenol was redetermined under constant instrumental conditions. The variation of the electrical resistivity of the three alloys under consideration with temperature on slow cooling is illustrated. An anomaly in the disordering process near the Fe3Al -- FeAl transformation temperature was manifested in the stoichiometric Fe3Al alloy. Above a temperature of 490 deg C there was a rapid decrease in the integrated intensity of the (210) FeAl superlattice reflection. The best ductilities obtained corresponded to heat treatments involving slow cooling to produce a high degree of Fe3Al order and subsequent annealing of the ordered material for short periods of time near the Fe3Al -- FeAl transformation temperature.

Available in PDF, EPUB and Kindle. Book excerpt: Deformation mechnisms in Fe-Al single crystals were studied. and observations regarding deformation structures are discussed. In surface- preparation studies. a polishing technique was developed which requires only that the chemical bath temperatures be controlled and thnt the bath be agitated. Bath composition is given, and results obtained with Thermenol treated by this technique are included. (J.R.D.).

Book excerpt: The objective of the program is to determine the effect of variations of aluminum content, heat treatment, surface preparation, and other metallurgical factors upon the room-temperature ductility of Fe-- Al alloys. As a continuation of the metallographic deformation studies, two coarse-grained tensile specimens of 13.9-Alfenol were heat treated, electropolished, and pulled to fracture. (W.L.H.).

This book was released on 1960 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Resistivity specimens of 16-Alfenal and Thermenal were machined from the as-rolled 0.035-in.-thick stock, annealed for varying lengths of time at 650 deg C to obtain the desired microstructures, and prepared to establish a high degree of Fe3Al order. Resistivity measurements were made, the results of which are presented graphically. These isothermal resistivity curves were analyzed to establish the effects of heat treatment on the mechanical properties of the various alloys. Initial results of these studies are presented in relation to mechanical properties and hardness indentations. (For preceding period see TIDl1106.) (J.R.D.).

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program is to determine the effect of variations of Al content, heat treatment, and basic slip mechanism upon the room temperature ductility of Fe - Al alloys. Additional heat treatment studies on 13.9 Alfenol tends to confirm earlier observations that reproducibility of ductility values of 8 to 9% are difficult to obtain. The preparation of Al - Y - Fe, and Al - Mo - Y - Fe alloys by arc melting in a non-consumable electrode arc furnace is reported. A resistivity versus temperature curve for the 13.9% Al alloy containing 1% Mo was determined. (W.L.H.).
