Honda develops new technology to weld steel and aluminum together

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two dissimilar metals. That changed last Thursday, however, when Honda Motor Company announced that it has devised a technique for doing that very thing. The results, which include lower vehicle weight and better performance, can be seen in the 2013 Accord.Read More

NanoSteel promises lighter and more fuel efficient without compromising safety

With fuel costs continuing to rise, the search is on for ways to make cars lighter and improve fuel efficiency, without compromising strength and safety. NanoSteel, a Rhode Island-based company recently announced the development of new nano-structured advanced high-strength alloys whose strength and ductility meet automotive structural demands. The company plans on marketing its sheet metal products in 2013 and has recently received investment from GM suggesting they could soon be appearing in production vehicles.Read More

Graphene used to rust-proof steel

Hexavalent chromium compounds are a key ingredient in coatings used to rust-proof steel. They also happen to be carcinogenic. Researchers, therefore, have been looking for non-toxic alternatives that could be used to keep steel items from corroding. Recently, scientists from the University at Buffalo announced that they have developed such a substance. It’s a varnish that incorporates graphene, the one-atom-thick carbon sheeting material that is the thinnest and strongest substance known to exist.Read More

Delta Shelter provides almost indestructible living space

What do you do when you want to build a worry-free home on land that also happens to be a 100-year flood plain? If you're smart, you'll do what the owner of Delta Shelter did and have Olson Kundig Architects build you a metal fortress to withstand the elements in style. The compact 1,000 sq ft (93 sq m) steel-walled hideaway with a footprint of only 200 sq ft (18.6 sq m) looks ready to handle whatever the Washington wilderness can throw at it - even, perhaps, a 1,000-year flood.Read More

Self-taught metallurgist creates lighter, stronger steel in a flash

Having been around for a few centuries, steel is what is known as a “mature technology” and the basic process of heat-treating has remained largely unchanged in the modern age. So when self-taught metallurgist Gary Cola approached engineers at Ohio State University claiming to have found a way to increase the strength of steel by seven percent, they were justifiably skeptical. However, after the engineers tested steel produced using the new method, Cole’s claims were borne out and the engineers set about understanding what was happening.Read More

Metallic material can switch back and forth between hard and soft states

We may not yet have the liquid metal depicted in the Terminator movies, but scientists have now developed something that’s vaguely along the same lines. German materials scientist Dr. Jörg Weißmüller and Chinese research scientist Hai-Jun Jin have created a metallic material that can change back and forth between being strong but brittle and soft but malleable, via electrical signals.

Metallic glass parts can now be created in milliseconds

What do you do if you want a material that’s as hard as glass, but that can bend without shattering, like steel? Well, if you’re a researcher at the California Institute of Technology (Caltech), you invent metallic glass. There are several types of metallic glass – which is said to be stronger than steel or titanium – all of which consist of a metal with the disordered atomic structure of glass. Although it’s been possible to produce the material in bulk since the early 90s, the production process has limitations, that have kept metallic glass from coming into common use. Now, however, a Caltech team has come up with a new process, in which the material can be shaped as easily as plastic.Read More

Save those cigarette butts, and use them to protect steel

It has been estimated that every year, 4.5 trillion cigarette butts are added to the world’s ecosystem. That would be bad enough if they were simply disgusting, but when they’re left on beaches or washed down storm sewers, they can be lethal to fish. Unfortunately, there’s nothing that can be done with the butts, other than throwing them out... until now, perhaps. Researchers from China’s Xi’an Jiaotong University claim that cigarette butts can be used to make an excellent rust inhibitor.Read More

Mosquito Electric Bike by Toto Design

With a very sturdy folded steel frame and elegant simple design, the Mosquito or Mücke electric bike is one good-looking machine. Its 48V lithium batteries only cost a few (European) cents to charge up and will give a range of about 60km (37 miles). The 0.8kW motor produces a top speed of around 50km/h (31mph) and the bike also has a removable center pole for instant accessibility.Read More
