This book was released on 1963 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the second phase of an investigation to improve welds in high strength aluminum alloys such as 7075 and 7178. Direct current, straight polarity, helium shielded tungsten arc automatic welding was preferred for most consistent results, although highest individual weld strengths were achieved with carefully controlled consumable electrode short arc technique. High travel speeds, with TIG welding, decreased weld strength because of small hot-short cracks. Cold working of welds before aging often caused cracks and had no beneficial effect on strength. Locally heat treating welds with a low power arc before aging increased ductility in both tensile and bulge tests. Strength was about equivalent to no heated welds. Base metal properties determined after short time exposure to high temperatures were used to predict joint designs for local heat treatments.

Download or read book The 9Ni-4Co Steels written by T. P. Groeneveld and published by . This book was released on 1966 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum briefly discusses the physical metallurgy, heat treatment, mechanical properties, stress-corrosion properties, and fabrication of the 9Ni-4Co-XC steels. This family of steels was developed specifically to meet the requirements of the aircraft and aerospace industries for materials possessing high strength and high toughness. By varying the composition and heat treatment, the 9Ni-4Co-xC steels can develop strengths in the 200 to 300 ksi tensile-strength range and reportedly possess high toughness. The lower carbon grades have excellent weldability, developing strength in the 180 to 200 ksi range with high toughness without the need for preheat or postweld-heat treatment. (Author).

Book Synopsis The effect of post welded heat treatment on mechanical properties and microstructure of friction stir welded Al 6063 by : Jasveer Singh
Download or read book The effect of post welded heat treatment on mechanical properties and microstructure of friction stir welded Al 6063 written by Jasveer Singh and published by BookRix. This book was released on 2018-01-11 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials Welding plays a crucial role or say as a back bone of manufacturing industry to join the components. Friction stir welding (FSW) is a relatively new joining process that has been demonstrated in a variety of metals such as steel, titanium, lead, copper and aluminium. The unique properties of friction stir welds make possible some completely new structural designs with significant impact to ship design and construction. Friction stir welding is especially advantageous for joining aluminium and has been exploited commercially around the world in several industries. In the present work the effects of welding speed have been investigated on the microstructural and mechanical properties of friction stir welded aluminium alloy 6063. FSW was carried out at rotational speed of 1300 rpm (constant) and transverse speeds of 35, 50 and 65 mm/min. Mechanical performance has been investigated in terms of hardness, wear resistance and tensile strength. To study the effect of post welding heat treatment on properties of friction stir welded joint, the artificial ageing was carried out at 1600 C for a soaking period of 20 hours in the muffle furnace. The study revealed that friction stir welded joint prepared at welding speed of 35 mm/min exhibited better tensile strength, hardness and wear resistance. Better mechanical properties of the joint prepared at welding speed of 35 mm/min may be attributed due to fine, homogeneous and equaxed grain structure of stir zone. Post welding heat treatment of friction stir welded joint improved the wear resistance and microhardness of the joint. However tensile properties deteriorated with the post welding heat treatment of joint.

Book Synopsis Fundamental Study on Nanoparticle Interaction with Hot Crack Susceptible Aluminum Alloys During Arc Welding by : Maximilian Sokoluk
Download or read book Fundamental Study on Nanoparticle Interaction with Hot Crack Susceptible Aluminum Alloys During Arc Welding written by Maximilian Sokoluk and published by . This book was released on 2020 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today's society, the manufacturing of complex structures and assemblies is of vital importance in the design and engineering process. In this context, fusion welding has proven to be an invaluable method from large scale automotive assembly lines to high tech aerospace applications. With the growing call for energy-efficient solutions, the demand for high strength aluminum alloys in these applications is evident. Therefore, when incorporating these materials into profitable production processes, a material's weldability becomes crucial. While high strength aluminum alloys such as AA7075 and AA2024 are considered unweldable due to their high susceptibility to hot cracking, the medium strength AA6061 is only weldable with limitations. The dissimilar filler metals used to mitigate hot crack susceptibility leave the weld metal with limited strength, ductility, corrosion resistance, and heat treatability. Therefore, this study aims to eliminate the intrinsic susceptibility of introduced aluminum alloys using filler metal of similar chemical composition treated with refractory nanoparticles, i.e., nano-treating (NT). Filler metal containing a volume fraction of 0.8 v% of TiC (7075NT-C, 2024NT-C, and 6061NT-C) and a volume fraction of 0.8 v% TiB2 (7075NT-B, 2024NT-B, and 6061NT-B) nanoparticles were produced, matching the constituent element composition of their respective commercial aluminum alloys. In addition, the industrially applied filler metal ER5356 was nano-treated with 0.8 v% TiC (5356NT-C) and 0.8 v% TiB2 (5356NT-B), respectively. The welds performed with similar nano-treated filler metal showed a remarkable grain refinement and morphology control, whereas the use of TiC-containing filler metals was deemed more effective than their TiB2 -bearing counterparts. The transversal tensile properties of the welded joints showed an increased weld metal hardness in as-welded condition and virtually wrought transversal tensile properties by applying a post-weld heat treatment to the specimens. The Houldcroft hot crack susceptibility tests conducted showed a significant reduction in the weld metals' susceptibility to hot cracking when comparing tests performed with nano-treated filler metal to tests performed with the respective base metal as filler metal. It was noted that the crack reduction achieved with NT-C filler metal slightly exceeded that of tests performed with NT-B. An in-depth thermal analysis investigating the solidification behavior of nano-treated alloys revealed a three-fold mechanism caused by the refractory nanoparticles. It was shown that nanoparticles significantly alter an aluminum alloys solidification process from liquidus to solidus temperature and cause unprecedentet changes to the materials resultant microstructure. This new finding strongly contradicts observations made with the use of conventional grain refiners and mitigate an aluminum alloys susceptibility to hot cracking.
