We’ve recently seen aluminum put to work on an auto easily associated with reliable power: the Ford F150 Pickup. As Ford opted to switch from steel for the construction of the F150’s body and customers responded with enthusiasm, the industry started wonder if aluminum would replace steel as the go-to material for other commercial cars and trucks.
Such developments have some steel suppliers concerned and aluminum manufacturers embracing the switch by actually working to develop new aluminum alloys specifically for new automotive applications. Both sides may have goods reasons to respond as they are, especially as aluminum is going beyond use in the average commercial auto and on to luxury market.

Making Luxury Lightweight
Just as the Ford F150 is associated with toughness, the name Roll Royce has long been considered the pinnacle of classic automotive opulence. The company must regularly meet and exceed the very high expectations of their customers, but they must also adapt to changing automotive standards that call for greater efficiency without compromise of safety and performance.
In an effort to lighten the weight of their next generation of the Phantom Coupe, Rolls Royce will be using an all-aluminum architecture in the construction of the vehicle. Rolls Royce will also be employing the material on the architecture of the company’s Ghost sedan.

How Long Before Aluminum Dominates?
While aluminum has a long way to go before it becomes anywhere near as dominant as steel, the lightweight material has become a primary integration in autos that claim greater fuel economy. From your average suburban parking lot, to the garage of an extravagant estate, you may be all the more likely to find an increasing amount of aluminum in new automobiles.
Do you think Ford and Rolls Royce will continue to see success as a result of their new aluminum employment? Share your thoughts in the comments.
Cement Industry Exploring CO2 Pollution Reduction Strategies
Cement plays a critical role in almost all infrastructure and construction. As a result, cement making represents a massive global industry that contributes significantly to CO2 pollution. Producing cement accounts for 7 to 8 percent of annual CO2 emissions worldwide. Confronted by this large carbon footprint, the cement industry is turning to carbon-capturing techniques and renewable energy sources to reduce emissions.
One approach to carbon capture involves trapping CO2 within the cement material itself. Researchers have experimented with mineralized CO2 and mixing it into the cement and other aggregates when making concrete.
An alternative method injects CO2 into the wet mix during pouring. As the final product cures, the gas remains trapped inside the solid material. CarbonCure and Solidia already have used these methods at construction sites and in the manufacturing of precast concrete blocks.
Cement represents 80% of the CO2 emissions attributed to concrete usage. Material scientists have reduced cement needs through the use of substitutes, like iron slag and coal ash. Limestone calcined clay offers another binding agent that offers the benefit of lower production expenses.
In the U.K., the Energy Safety Research Institute from Swansea University has installed a green hydrogen power generator at a Heidelberg Cement facility. When using power from renewable sources, the unit splits hydrogen and oxygen atoms from water molecules. The separated hydrogen provides a clean-burning fuel to power cement processing. This reduces reliance on fossil fuels and cuts CO2 emissions. Additionally, hydrogen fuel trucks could replace diesel trucks currently used to transport cement.
Advances in concrete technologies have the potential to preserve the use of a versatile building material while addressing pollution. How effective do you think carbon capture and renewable fuels will be at decarbonizing the cement industry?
CarbonCure’s vision is to make its carbon dioxide removal technology standard for all concrete production across the globe. By realizing the full potential of CarbonCure’s portfolio of technologies, the goal of saving 500 megatonnes of embodied carbon emissions every year could be met—which would be equivalent to taking 100 million cars off the road.
In order to shrink the carbon footprint of buildings, embodied carbon in new buildings must be reduced. Embodied carbon, or the carbon emitted from the manufacturing of building materials and construction, will account for nearly 50% of carbon emissions from new construction over the next 3 decades. In any given building, concrete can contribute a minimum of 50% of the embodied carbon footprint.
ABOUT Solidia Technologies Inc.
Solidia Technologies has developed a technology platform that enables production of next-generation building and construction materials with outstanding physical properties, lower life-cycle costs and low environmental footprint. Solidia’s “Low Temperature Solidification (LTS)” technology accelerates the natural bonding process of CO2 with minerals to form solids, ensuring that it happens in hours rather than years.
In the building materials industry, this enables the production of stronger and more durable products ranging from facades to floor and roof tiles to decorative countertops. Solidia Technologies is also working to develop materials that can replace concrete. Preliminary findings show that the strength and properties of these materials far exceed those of traditional concrete. The sequestration of CO2 in the production process provides the additional benefit of creating a carbon neutral concrete replacement.

New Type Of Steel Offers High Strength, Ductility, And A Lower Price
Usually, higher strength steels provide less ductility, and vice-versa. Materials scientists and engineers continuously look at methods for getting the most of these two qualities within a single alloy. Researchers in China and Taiwan may have gotten closer, as they’ve developed a new metal manufacturing technique that’s said to yield steel that’s both strong and ductile, and also considerably less expensive than many industrial steels used today.

Strong, Ductile, Lower Cost Breakthrough Steel
The new technique has been referred to as deformed and partitioned (D&P). While the researchers have not revealed many specifics of D&P, the process yields a material that can be defined as a “breakthrough steel”, containing 10 percent manganese, 2 percent aluminum, 0.47 percent carbon, and 0.7 percent vanadium. Cold rolling and embedding of metastable austenite grains are also used in the technique, which creates, what researchers call, a highly dislocated martensite matrix. The matrix allows the steel to retain ductility even as strengthening qualities are incorporated.

Five Times Cheaper Than Aerospace And Defense Alloys
Apart from the dual physical advantages to the new steel, the production process is cheaper than that used to create steel grades that are commonly used in aerospace, defense, and other critical applications. The research team claims that their steel costs one fifth the price of production for aerospace and mil-spec steel, while offering the same characteristics of those alloys.
How Will It Impact Industry?
The study detailing the development of the super steel was published in Science on August 24th, 2017. How the technique and the resulting steel will impact the many industries that use comparable alloys is yet to be known.
