Publication number: 20120121923Abstract: Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The CTE of the fine-grained metallic coating is matched to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.Type: ApplicationFiled: January 26, 2012Publication date: May 17, 2012Applicant: INTEGRAN TECHNOLOGIES INC.Inventors: Gino Palumbo, Jonathan McCrea, Klaus Tomantschger, Iain Brooks, Daehyun Jeong, Dave Limoges, Konstantinos Panagiotopoulos, Uwe Erb

Publication number: 20120098134Abstract: When connecting with a conventional Zn/Al/Zn cladding material, thickness of a connecting part needs to be less than double an existing high-lead solder (about 100 ?m) in order to make heat resistance in the connecting part at least equivalent to a level of the existing solder. Moreover, thickness of an Al layer needs to make as thick as possible in order to fully exhibit stress relaxation performance of the Al layer. Provided is a semiconductor device including a semiconductor element, a frame, and a connecting part which connects the semiconductor element and the frame to each other, in which an interface between the connecting part and the semiconductor element and an interface between the connecting part and the frame respectively have the area of Al oxide film which is more than 0% and less than 5% of entire area of the respective interfaces.Type: ApplicationFiled: August 30, 2010Publication date: April 26, 2012Inventors: Masahide Okamoto, Osamu Ikeda, Yuki Murasato

Publication number: 20120088116Abstract: A method of forming a bimetallic forging includes providing a blank comprising at least a first element and a second element of a first metal, and an insert of a second metal. A blank is configured such that the insert may be substantially encapsulated by a shell defined by the first element and the second element. The blank is forged to form a bimetallic forging including an outer portion defined by the shell, an inner portion defined by the insert, and an interface layer therebetween. In a non-limiting example, the first metal is substantially comprised of aluminum and the second metal is substantially comprised of magnesium. In a non-limiting example, the blank may be forged to form a vehicle wheel including an aluminum skin substantially encapsulating a magnesium inner portion, providing wheel with a high strength to weight ratio and improved corrosion performance.Type: ApplicationFiled: October 12, 2010Publication date: April 12, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Blair E.
