This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was the development of a thermomechanical procedure to process Aluminum-Magnesium alloys and testing effects of alloying additions on these alloys. Magnesium contents of eight and ten weight percent and the alloying effects of copper and manganese were studied. Microstructures and mechanical properties at six warm rolling temperatures located above and below the solvus line of these alloys were examined. Ultimate tensile strengths in excess of 680 MPa (99 KSI) were obtained. Microstructural evidence indicated that the precipitation of the 'beta' intermetallic phase was one of the most important mechanisms in controlling the strength of the alloy. Furthermore, precipitation is so rapid at higher temperatures that it becomes the strongest force within the microstructure and its presence prevents any possible recrystallization of the alloy. However, when the temperature exceeds the solvus temperature for the alloy, recrystallization does occur with large losses in both yield and ultimate tensile strength. (Author).

This book was released on 1979 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructures and mechanical properties resulting from thermomechanical processing of high-Magnesium (Mg) content Aluminum-Magnesium (Al-Mg) alloys were investigated in this research. Warm rolling processes, intended to refine both grain size and second phase Al3Mg2 (beta) particle size, were conducted for alloy compositions of 10.2 weight % Mg, 10.2 weight % Mg plus 0.5 weight % copper (Cu) and 12.1 weight % Mg. Solution treatment, hot upset forging, resolutioning and rapid cooling provided initial microstructural homogenization. Subsequent warm rolling was employed to refine the microstructure. The effect of warm rolling parameters of beta particle size and distribution was of particular concern. By warm rolling an alloy containing 10.2 % Mg plus 0.5 % Cu at 250 C, an ultimate tensile strength of 565 MPa (82000 psi), with 11.5 % elongation, was achieved with the added advantage of a strength to density ratio higher than present equivalent-strength alloys, such as 7075-T6.

Available in PDF, EPUB and Kindle. Book excerpt: Titanium-Tantalum shape memory materials have widespread potential in biomedical applications due to their high degree of biocompatibility, favorable mechanical properties, high corrosion resistance and the possibility of exhibiting shape memory behavior 5' 6, 9. However, this system faces difficulties in processing due to the slow diffusion of Ta, with a melting point of 3269 K, and the sensitivity of shape memory materials on composition and processing history 8' 9 Dynamet Technology, Inc. has engineered a process in which these difficulties are overcome via powder metallurgy techniques, and the objective of this work was to characterize and explore the relationship between Dynamet's processing steps and the microstructure and properties of the Ti - 30 wt % Ta systems . Energy-dispersive x-ray analysis was used to quantify compositional gradients to verify homogeneity. Room temperature and high temperature x-ray diffractometry was used to identify phases present at temperatures ranging from room temperature up to 750 [degree]C. Hot extrusion without further heat treatment was found to be insufficient to produce a homogenous, fully dense alloy. Elongation, an indicator of potential shape memory behavior, was shown to increase with increased martensite phase fraction, which is thought to be dependent on cooling rate from above the austenite phase transformation starting temperature, Af. Finally, a phase transformation, likely that of martensite into beta-Ti, was verified to exist between 400 - 600 [degree]C.

Available in PDF, EPUB and Kindle. Book excerpt: In Ti-10-2-3 a variety of aged microstructures with different volume fractions and morphologies of primary and secondary alpha and also grain boundary alpha has been tensile tested. The results can be summarized as follows: (1) For a constant volume fraction of primary alpha it is possible to vary the yield stress in a wide range; it is also possible to reach comparable yield stress levels for different volume fractions of alpha by an appropriate choice of aging temperatures and times as well as heating up rates to the aging temperatures; (2) Increasing the volume fraction of primary alpha reduces the ductility at comparable yield stresses for the alpha-aged conditions. Only the beta-ST conditions with no primary alpha are an exception. They have lower ductilities than the (alpha + beta) ST conditions. The omega-aged microstructures have the lowest ductilities at comparable yield stresses; (3) The differences in ductilities between the (alpha + beta) ST and alpha-aged, the beta-ST and alpha-aged and the omega-aged microstructures are qualitatively related to different fracture modes; and (4) Microstructures from a different forging which instead of the above tested globular primary alpha have elongated primary show lower ductilities at comparable yield stresses.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of heat treatment on the microstructure of the metastable beta alloy Ti-10V-2Fe-3Al has been studied using light and electron metallography, analytical electron microscopy, and X-ray diffraction. A limited survey of the effect of microstructure on tensile properties of the alloy also has been conducted. It has been found that the alloy contains inclusions which are rich in Ti, S, Si, and P. The alloy has been shown to form the omega phase both athermally and isothermally. The isothermal omega can have either an ellipsoidal or a cuboidal morphology. The reasons for this are enumerated. The formation of the equilibrium alpha phase has been studied, and three distinct modes of formation are described. A stress induced othorhombic martensite also has been observed. The effect of this stress induced product on tensile behavior is discussed. The relative roles of inclusions and alpha phase precipitates on tensile fracture also have been examined. (Author).

This book was released on 2007 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron addition to conventional titanium (Ti) alloys instigates precipitation of intermetallic TiB whiskers that provide significant increases in strength and stiffness. The eutectic composition is the maximum boron concentration that provides these benefits via melt processing while maintaining reasonable ductility and damage tolerance. The eutectic point for the most widely used Ti alloy, Ti-6Al-4V (weight percent), modified by B addition, was determined to occur at 1.55+0.05B and 1545+5?C. The microstructure, texture, and tensile properties of the eutectic alloy are sensitive to ingot solidification conditions and melt pool morphology. Several microstructural forms in the as-cast condition as well as their transformation during thermomechanical processing (TMP) were identified. Two types of eutectic structures, aligned and random, were obtained. Cast microstructures with random eutectic colony orientation had no marked crystallographic texture, while cast aligned microstructure had a strong [020] texture for the TiB phase and a 110 circular texture for the alpha-Ti phase.
