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 42 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.

This book was released on 1986 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine the mechanical properties and microstructural characteristics resulting from thermomechanical processing by warm rolling of an AL-8.0%Mg-0.5%Zr Alloy and an AL-8.0%Mg-1.0%Li-0.15%Zr Alloy. At ambient temperature, yield strengths were 38 to 44 Ksi (262-303 MPa), ultimate tensile strengths were 60 to 65 Ksi (414-45OMPa), with 10-12% elongation to fracture. Both alloys were moderately superplastic at 300C; an elongation of 340% was attained with the 1.0%Li alloy. Behavior of the alloy is consistent with continuous recrystallization during annealing and deformation at warm temperatures, and is very similar to that of previously studied AL-Mg-X alloys.

This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of different overaging temperatures and times prior to the rolling portion of a thermomechanical process (TMP) were examined to determine those combinations resulting in refined microstructures capable of supporting superplastic behavior. Specimens of processed Al 2519 were tension tested at elevated temperatures after varying TMP parameters. Enhanced ductility in comparison to unprocessed material was observed at all test temperatures in the range of 3OO-45O0C. Moderate superplastic ductilities (up to 300%) were encountered under some conditions. Backscattered electron imaging techniques coupled with quantitative microstructural analysis methods were used to examine both processed and deformed samples. The correlations among processing, microstructure and mechanical behavior are presented.

This book was released on 2021 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for both high-strength and lightweight metals for structural applications to increase vehicle mobility has driven an increase in the research and development of lightweight alloys, including those based on aluminum (Al), to replace commonly-used steel. When alloyed copper (Cu), Al alloys can exhibit high tensile strengths. However, Al-Cu alloys are difficult to join using fusion welding processes due to solidification cracking. To circumvent the issues that arise with fusion welding, friction stir welding (FSW) can be employed. FSW is a solid state joining method that utilizes friction generated heat between a rotating tool and two metal plates to create a joint without the use of additional material. FSW temperatures are lower than the melting point and are historically achieved by controlling the welding speed. The welding temperature has largely been both an uncontrolled and unmonitored variable, which presents an issue when trying to predict or explain the weld microstructures. In addition, most FSW investigations are performed on parts that are less than 12 mm thick. This limits the understanding of processing-microstructure-property relationships of thicker FSW plates. This dissertation studied the effect of FSW on the microstructure and mechanical behavior of 25 mm thick AA2139-T8, a precipitation strengthened Al-Cu-Mg-Ag alloy. Processing-microstructure-property relationships were studied using both constant-speed (150 RPM and 50 mm/min) and constant-temperature FSW (performed at 490 ℗ʻC, 500 ℗ʻC, and 510 ℗ʻC). The microstructural evolution throughout the thickness of the weld was analyzed via optical microscopy, SEM, TEM, and XRD. The mechanical behavior was analyzed using tensile and Vickers hardness experiments. The distribution of the different precipitates was plotted throughout the welded area for the constant-temperature FSW materials. The average matrix grain size decreased from the weld top to bottom, while the precipitate volume percent increased from the weld top to bottom. The stir zone (SZ) exhibited lower strengths and hardness than the base metal. In addition, the larger grains in the upper weld nugget (UWN) of the SZ had a higher hardness than the smaller grains in the lower weld nugget (LWN) of the SZ and this was explained by the dissolution of the precipitates during welding and the associated solid solution strengthening. This study was the first to perform constant-temperature FSW on both an Al-Cu-Mg-Ag alloy and a 25 mm thick plate. Compared with the 500 ℗ʻ and 510 ℗ʻC constant-temperature FSW, the 490 ℗ʻC constant-temperature FSW yielded the smallest average grain size and the highest precipitate volume percent through the SZ. The average grain size increased with welding temperature. The 510 ℗ʻC FSW exhibited the lowest room-temperature (RT) tensile YS, UTS, Îæf, and joint efficiency due to the void formation during the welding. The 490 ℗ʻC and 500 ℗ʻC FSWs failed at the interface between the SZ and the thermomechanically affected zone (TMAZ) and in the HAZ, respectively, which were the weakest links of the weld and dictated the tensile properties. The work in this dissertation provided new insights into the effects of constant temperature FSW on the microstructural evolution and the mechanical properties through the weld thickness. The knowledge gained from this work will not only assist in determining optimal welding parameters for this alloy for targeted applications, but will also serve as a framework for future research targeted at understanding processing-microstructure-property relationships of a variety of metallic systems undergoing not only FSW under controlled conditions but also undergoing different controlled thermomechanical processing treatments.
