Steel

An aluminum piston (left) and one of the new steel pistons (right)

In 1936, Mercedes-Benz became the first company in the world to launch a diesel passenger car – the 260D. Over the years, diesel automobiles became renowned for their efficiency and fuel economy. Now, the manufacturer is building on that success with the introduction of high-tech steel pistons.  Read More

Researchers have increased the toughness of various metals by giving them a 'gradient stru...

Steel is a common benchmark against which the strength of materials is measured, with "stronger than steel" a familiar catch cry for those touting the properties of some new space-age material. But now researchers at North Carolina State University have created steel that is stronger than steel using a process that increases the toughness of various metals by altering the microstructures within them.  Read More

Arup has developed a method for 3D printing steel elements

Arup says it has developed a 3D printing technique for creating structural steel elements to be used in construction. Although laser sintering has been used elsewhere, Arup believes this is the first time it has been used for this purpose. The technique could reduce energy usage, costs and waste.  Read More

Taizhou Bridge under construction

The 2,940-m long Taizhou Bridge has won the Supreme Award for Structural Engineering Excellence at this year's Structural Awards. The event gives the nod to a variety of structures across numerous categories, but it was the three-tower, long-span suspension bridge, the first of its kind, which received the overall "Supreme" gong. Read more about the project and the individual category winners after the cut.  Read More

The Impromptu Tactical Pen is designed for danger, as a pen suitable for the police and ar...

While the chances of being caught up in a dangerous situation are thankfully low, having something about your person for such an eventuality isn't a bad idea. The Impromptu Tactical Pen from Gerber, with its glass-breaking steel tip, is one option for those who want to keep themselves safe. It is, as its name suggests, a simple writing implement with a hidden extra that could mean the difference between life and death.  Read More

The imposing metal outer shell of the Rooftecture OT2 house in the heart of Osaka, Japan m...

They say that walls can talk and if the cold, windowless metal exterior of the Rooftecture OT2 house in downtown Osaka, Japan says anything, surely it's "Leave me alone." Those lucky enough to make it through the front door (complete with forbidding chainlink door handle), however, are in for a bit of a shock. In stark contrast to its outer shell, the family home offers a warm and welcoming diffused light and mixed wood interior comfortably spread over three levels.  Read More

A diagram of an Accord subframe made using the new welding process

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's nano-structured steel materials can help automakers such as GM to make lighter...

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

A piece of steel treated with the graphene varnish, in front of an untreated sample

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

The Delta Shelter provides secure living with low impact and a small footprint (Photo: Ols...

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
