The aerospace industry, which is largely responsible for development of advanced alloys that benefit a range of other industries. More than any other group, aircraft manufacturers rely on the steady improvement of materials and fabrication methods for increased efficiency, higher speeds, and greater reliability and durability. Because of the efforts put forth by a multitude of engineers and scientists, aerospace has become one of the few success stories in American manufacturing. It is a...Read Full Story

Laser welding of titanium 6Al-4V has been developed for producing near net shape structural components. Process parameters have been identified for producing very repeatable, high-quality welds on a variety of material thicknesses and joint configurations.Extensive metallurgical examinations and preliminary mechanical property evaluations have been done to qualify this process for fabricating structural parts. It has been found that the mechanical properties of automated laser welded titanium...Read Full Story

Allegheny Technologies Incorporated’s next-generation ATI 500-MIL armor steel has been selected for an armored situational awareness kit on the U.S. Army’s Stryker Light ArmoredVehicles, marking the first major legacy-vehicle military application for this specialty metal. The add-on kit, known as the StrykShield, is comprised of front and side transparent armor windows that are mounted in a framework built with ATI 500-MIL high-hard armor steel. Produced by Carapace Armor Technology, the...Read Full Story

An introduction to friction stir welding By Jeff Defalco, Contributing Writer September 15, 2009 A relatively new joining process, friction stir welding (FSW) produces no fumes; uses no filler material; and can join aluminum alloys, copper, magnesium, zinc, steels, and titanium. FSW sometimes produces a weld that is stronger than the base material. Friction stir welding (FSW) is a relatively new joining process that has been used for high production since 1996. Because melting does not occur...Read Full Story

PhD studentship: Origine and nature of metastable intermetallic compounds produced by thermomechanical joining processes of metals Job description: Friction stir welding (FSW) is currently a growing process of solid-state joining. Under development since a decade, its main advantage lies in the absence of intrinsic defects unavoidable in usual liquid-state joining processes. However, the [...]Read Full Story

Taisei Plas Co., Ltd (Tokyo, JP) inventors Masanori Naritomi and Naoki Andoh  developed a patent pending method to manufacture lightweight and strong composites of a magnesium alloy and carbon fiber reinforced plastics (CFRP), by strongly bonding the magnesium alloy and the CFRP using an epoxy adhesive. The magnesium alloy has specific ultra-fine irregularities is compatible with an epoxy resin adhesive and exhibits thus strong adhesion.  The manufacturing processes are detailed in U.S...Read Full Story

Anovel two-phase alloy of composition Fe- 20Ni-35Mn-15Al (all compositions in atomic percent) was produced by arc melting. Disk samples of 3 mm diameter were electro-polished in a mixture of 20% nitric acid, 10% butoxyethanol, and 70% methanol by volume at 253K (–20°C, –4°F).The resulting thin foils were examined in a Technai F20 field emission gun TEM operated at 200 kV. Selected area diffraction showed that the phases present were B2 (ordered body centered cubic) and face-centered cubic...Read Full Story
