Memory-steel -- A new material for the strengthening of buildings

Researchers from Empa and re-fer AG have developed a new building material called memory-steel, which uses shape-memory alloys to permanently prestress concrete structures. The material eliminates the need for hydraulic prestressing, reducing space requirements and making it suitable for confined spaces.

Detecting damage in non-magnetic steel with the help of magnetism

Scientists from JGU and the University of Kaiserslautern have developed a process to apply a thin magnetic layer to steel, allowing for the detection of microstructural changes by changes in magnetic effects. This method has the advantage of detecting signs of fatigue much earlier than conventional testing procedures.

Monitoring molten steel by laser:

A new laser technology developed by Swansea University has won the Materials Science Venture Prize, allowing for real-time monitoring of molten metal furnaces without stopping production. This innovation saves steel plants up to £4.5 million a year and can be applied to various metals such as aluminium and copper.

Lightweight metal foam blocks blastwave, debris from high-explosive rounds

Researchers at North Carolina State University have developed a new material, stainless steel composite metal foam (CMF), that offers much more protection than existing armor materials while lowering the weight remarkably. The CMF can block blast pressure and fragmentation from high-explosive incendiary rounds with minimal weight loss.

Super wood could replace steel

Researchers at the University of Maryland have created a new type of wood that is 10-12 times stronger than natural wood, making it a potential competitor to steel. The wood's mechanical properties are comparable to those of titanium alloys, but with improved toughness and reduced weight.

Man(ufacturing) of steel

Researchers at the University of Pittsburgh are developing new steel alloys for additive manufacturing with a focus on high-strength low-alloy steels suitable for naval construction and repair. The project aims to improve mechanical properties and corrosion resistance using integrated computational materials design.

Toronto's subways expose passengers to more air pollution than Montreal, Vancouver systems

A new study found that Toronto's subways have the highest levels of airborne particulate matter in Canada, with average values up to 100 micrograms per cubic metre, compared to Montreal's 36 micrograms and Vancouver's 17 micrograms. The high metal content and abrasive wear on steel wheels may be contributing factors.

Conquering metal fatigue

A team of researchers at MIT has developed a novel material with a laminated nanostructure that reduces metal fatigue, allowing it to deform without spreading microcracks. This breakthrough could lead to improved structural components in industries such as aerospace and automotive.

Parametric analysis on collapse-resistance performance of reinforced-concrete frame with specially shaped columns under loss of a corner column

The study found that increasing beam section height and lower steel bar rebar ratio significantly improves collapse-resistance capacity. Meanwhile, lengthening the specially shaped column limb only enhances stiffness, while slab upper and lower steel bar rebar ratios increase the frame's stiffness and collapse-resistance capacity.
