At Alcoa, ICME is enabling Alcoa engineers to accelerate the development of new alloys, new products and manufacturing processes. We have developed a hot tearing prediction approach which directly couples the hot cracking tendency calculation with the phase equilibrium calculation for component aluminum systems.
Keywords: Thixoforming, New Rheocasting, alloy development, Aluminum-Lithium 1 Introduction A scientific group of the RWTH Aachen Uni-versity have been investigated the technologi-cal aspects of semi solid processing of metals within the scope of a 9 year collaborative research action (SFB 289). Semi solid tech-nology is defined by a processing of metals in the semi solid state between solidus ...
AbstractThis paper presents a systematic survey on the formation of recrystallisation textures in cold rolled Al alloys. In particular, the nucleation of new grains in cube bands, grain boundaries, shear bands, and the deformation zones around large pProceedings of Conference 'Texture on a Mircoscale' as well as their subsequent growth into the deformed matrix are examined and .
Alloy development, begun in 1911, improved physical properties and opened new industrial fields. The Great Depression resulted in Works Progress Administration (WPA) projects that expanded hydroelectric generation capacity, which in turn increased production capacity of primary aluminum. During this time, the Aluminum Association was formed. The Association's first meeting was held in New ...
The proposed range of compositions can be recommended for development of new aluminium wrought alloys, which will have two main advantages compared with the commercial alloys of the AA2219 type: i) high tolerance to heating up to 300 °C because of the high amount of Al 3 Zr and Al 20 Cu 2 Mn dispersoids; ii) energy efficient processing, in particular due to the elimination of .

New Aluminium Alloy Development Introduction. Among aluminum alloys for die casting, Al-Si-Mg die casting alloys (JIS ADC 3 etc.) are known to be more ductile than Al-Si-Cu based die cast alloys (JIS ADC 12 etc.). In addition, with additional T6 heat treatment, appropriate strength can be obtained, hence, the former are commonly used for automobiles chassis parts and motorcycles body parts ...

Development of Aluminum Alloy Fin Stock for Heat Exchangers Using Twin-Roll Continuous Casting Method and subsequently brazed at temperatures near 600°C. The heating temperature of 600°C is close to the melting point of the aluminum alloy, so that various influences are exerted on its characteristics.
2019-04-24· New Aluminum Alloy Development The vast majority of alloys (amounting to more than 5,500 in number) that are in use today cannot be additively manufactured. This is because the melting and solidification process during the printing process leads to intolerable microstructures.
During the two years of funding, the first step will be to further develop an already available high-performance alloy in such a way that it can also be used in space travel. At the same time, the scientists want to develop a novel aluminum alloy with similarly outstanding material properties as the already available high-performance alloy, but as a cost-effective alternative.
addition to the development of aluminum foundry alloys, this approach has also be en succesfully used for many other applications, such as welding filler alloy development and additive manufacturing alloy development.
