A team of researchers from the University of Cambridge, ESA-ESTEC, and the Imperial College in London, have developed a model to evaluate fatigue crack growth in Shape Memory Alloys (SMAs). The goal of the model is to serve as a basis for a linearised system that will provide insight into the exact roles of transformation […]
Read MoreFormer U.S. President Donald Trump’s vision for raising an impermeable border in the south has failed to realize, but not before a whopping $16.4 billion was spent in funding the barrier construction. Now, hundreds of thousands of steel bollards, each costing about $9,000, lie in piles at various locations, rusting, creating an environmental hazard, and […]
Read MoreSteel is a very resilient material in general, but when it comes to subjecting it to harsh environments like seawater, you need to apply an anti-corrosive coating or it will rust pretty quickly. Researchers at the Rice University in Houston have tested a novel insulating material made out of sulfur and selenium and found that […]
Read MoreResearchers at the University of Hong Kong have developed a novel type of stainless steel alloy that kills the COVID-19 virus within six hours. More specifically, the steel can deactivate 99.75% of the virus in three hours and reach a final 99.99% in six. This anti-pathogen steel would be ideal for surfaces that come into […]
Read MoreAdvances in electric motors and battery technology have triggered an explosion in the field of electric airplanes. Battery-powered electric aircraft could be the future of aviation. A raft of companies are making green aircraft. EasyJet with Wright Electric, Boeing with Zunum, and Airbus with Siemens are all in the race to create electric aircraft to go green. Now, the aero-engine manufacturer […]
Read MoreIberdrola has partnered with H2 Green Steel to develop a major facility that will produce about 2 million tons of ‘green iron’ annually, using green hydrogen instead of natural gas. The project will cost $2.6 billion, and it is expected to send ripples of turbulence in a field that is currently lacking behind in implementing […]
Read More3D printing or additive manufacturing may be generally known as a “shaping technology,” but as scientists at the City University of Hong Kong proved, it can be much more than that. The team of Chinese engineers successfully developed a novel titanium alloy by using a 3D printer to design the microstructures of the material, ending […]
Read MoreEngineers at Sandia National Laboratories have carried out a series of tests on specially designed stainless-steel containers used by the U.S. Department of Energy for storing and transporting hazardous materials, and the results of the tests are confusingly inconclusive. The goal was to test what happens in the case of a fire and to see […]
Read MoreThermoacoustic combustion oscillations (TCO) are the peril of internal combustion engines, but detecting the phenomenon in time and taking targeted action to stop and reverse it has remained a complicated case. A team of engineers from the Tokyo University of Science and the Japan Aerospace Exploration Agency (JAXA) have developed a promising tool that detects […]
Read MoreElaine Thomas, a former metallurgist, and director at a foundry that provides steel to the U.S. Navy, has pleaded guilty in a Washington court, admitting to having falsified material strength test results numerous times in the past. This unethical practice has affected over 240 “cast high-yield” steel batches bought by the U.S. Navy for the […]
Read MoreResearchers at the North Carolina State University have developed a novel composite metal foam (CMF) which they claim is going to be a market-disrupting force. The material consists of metallic bubbles filled with air and then embedded within a metal matrix that can be made out of steel, aluminum, or any alloy. The benefit of […]
Read MoreRadiant, a California-based company has gathered funding for the development of a compact, low-cost portable nuclear microreactor. The one-megawatt nuclear micro-reactor has been designed for the areas where other power generation methods don’t work. This clean energy alternative to fossil fuels is compact enough to fit in a shipping container. It can power around 1000 homes. […]
Read MoreA team of material engineers in the Pacific Northwest National Laboratory, in Washington, have developed a novel manufacturing method for aluminum 7075, an alloy that is highly valued in the industry but one that is notoriously hard to extrude and very costly to make. The high cost derives from the inadequacy of conventional extrusion methods, […]
Read MoreThe EVRAZ Rocky Mountain Steel factory, a 150-year-old steel mill, is going to become the first in the world to get the energy it needs for production operations almost exclusively through solar power. The project was supported by Lightsource (EVRAZ sub-brand) and BP who commissioned a 300-megawatt solar farm on the EVRAZ property, using no […]
Read MoreNippon Steel, the Japanese steel-producing giant is suing Toyota, another colossus from Japan, seeking a court injunction that will stop the production of electric cars that infringe their patent. The patent that Nippon puts forth concerns a non-oriented electrical steel sheet that is used in electric vehicle motors. This key technology concerns the adjustment of […]
Read MoreRust is a sign of reaction taking place on the surface of metals, and usually, it is invasive and corrosive, so engineers intervene to stop it from eating and etching the metal. That is except for the protective film that is formed on some types of steel, used predominately in construction. But what happens with […]
Read MoreResearchers at Oak Ridge National Laboratory have developed a novel process to produce extreme heat-resistant carbon-carbon composites. Carbon-carbon composites, or reinforced carbon-carbon, are basically carbon fibers based on carbon precursors and carbon nano-tubes embedded in a carbon matrix. Every engineer loves it for its extraordinary mechanical properties such as the extremely high strength combined with […]
Read MoreRolls-Royce has proudly announced that its all-electric airplane, named the ‘Spirit of Innovation’, has completed its maiden voyage with success, proving its worthiness. The plane flew for approximately 15 minutes, taking off from and landing at the Boscombe Down site in the UK. This first flight is an amazing achievement that has been planned for […]
Read MoreChina’s steelmakers are shutting down their mills due to power rationing that was introduced by the government as a measure to mitigate power-cut problems. The Asian superpower has been having trouble balancing electric power supply and demand lately, and some provinces have experienced highly disruptive outages. This hasn’t left steel production unaffected, and considering that […]
Read MoreLotus has developed a new lightweight chassis called “LEVA” that is to be used in its upcoming EV models. The point that stands out about it is that it’s 37% lighter than the one used in Emira, an $82k sports car that was launched in 2021. The key in making such a leap is the […]
