PNNL team develops higher-strength, lower-cost titanium alloy aimed at improving vehicle fuel economy and reducing CO2 emissions
April 02, 2016
An improved titanium alloy—stronger than any commercial titanium alloy currently on the market—gets its strength from the novel way atoms are arranged to form a special nanostructure. For the first time, a team led by researchers at Pacific Northwest National Laboratory (PNNL) have been able to see this alignment and then manipulate it to make the strongest titanium alloy (hierarchical nanostructured Ti-185, or HNS Ti-185) yet developed. On top of the gains in strength, the new alloy benefits from a lower cost process.
In an open access paper published in the journal Nature Communications, the researchers note that that material is an excellent candidate for producing lighter vehicle parts, and that this newfound understanding may lead to creation of other high strength alloys.

Argonne study finds lightweight material substitution increases vehicle-cycle GHGs, but results in total life-cycle benefit
October 12, 2015
A team at Argonne National Laboratory has taken a closer look at vehicle-cycle (all processes related to vehicle manufacturing) and vehicle total life-cycle (vehicle-cycle plus fuel cycle—i.e., the use phase) impacts of substituting lightweight materials into vehicles.
In a study published in the ACS journal Environmental Science & Technology, they reported that while material substitution can reduce vehicle weight, it often increases vehicle-cycle greenhouse gas emissions GHGs—for example, replacing steel with wrought aluminum, carbon fiber reinforced plastic (CRFP), or magnesium increases the vehicle-cycle GHGs. However, lifetime fuel economy benefits often outweigh the vehicle-cycle, resulting in a net total life-cycle GHG benefit, they found. This is the case for steel replaced by wrought aluminum in all assumed cases, and for CFRP and magnesium except for high substitution ratio and low fuel reduction value.

GM using Continental Structural Plastics’ TCA Ultra Lite in Corvette for 20 lb weight savings
July 22, 2015
Continental Structural Plastics (CSP), a global provider of lightweight composite solutions, announced that its Tough Class A (TCA) Ultra Lite material, introduced in September 2014, is now in production on the 2016 Chevrolet Corvette. The use of TCA Ultra Lite, a Class A body panel material, results in a 20 lb (9 kg) weight savings on the Stingray Coupe model. This is the first production use of CSP’s Ultra Lite advanced composite.
Ultra Lite technology uses treated glass bubbles to replace some of the CaCO3 (calcium carbonate) filler, allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The treated bubbles also help with paint adhesion and bonding characteristics.

Ford’s first mass-produced carbon fiber wheels
July 12, 2015
To source the new lightweight track-capable carbon fiber wheels that are standard on the new Shelby GT350R Mustang, Ford partnered with Australia-based Carbon Revolution. Carbon Revolution first began delivering composite wheels in 2004 for Formula SAE campaigns. The company now is producing its “CR-9” wheel series in limited numbers for Porsche, BMW M3, Audi R8, Lamborghini and McLaren MP4-12C within Europe, Japan and North America. Ford, however, wanted more of a mass-production solution.
The one-piece carbon fiber wheels for the Mustang weigh nearly half that of an equivalent aluminum wheel (18 pounds versus 33 pounds), and handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40%, which positively impacts acceleration and braking performance. The wheels are so light, the springs and MagneRide dampers had to be recalibrated because the suspension can respond considerably faster to road inputs.

Researchers develop high-speed friction stir welding technique for aluminum joining at high volume production speeds
May 24, 2015
In partnership with General Motors, Alcoa and TWB Company LLC, researchers from the Department of Energy’s Pacific Northwest National Laboratory have developed a high-speed friction stir welding (FSW) process (earlier post) to join aluminum sheets of varying thicknesses—a key to producing auto parts that are light yet retain strength where it’s most needed—at speeds required for high volume production. The PNNL-developed process is ten times faster than current FSW techniques, representing production speeds that, for the first time, meet high-volume assembly requirements. The advancement is reported in an open-access paper in JOM, the member journal of The Minerals, Metals & Materials Society.
To create door frames, hoods and other auto parts, sheets of metal are welded together end-to-end into a “tailor-welded blank” (TWB) which is then cut into appropriate sizes before being stamped into the final shape. This process allows a high degree of customization. For example, a thicker gauge of metal can be used on one side of a car part, where extra strength is needed, joined via a weld to a thinner gauge on the side where it’s not.
