  • High energy X-rays reveal the resistance of steel to embrittlement

    The high energy X-rays at the Swedish Material Science beamline make it possible to see what’s happening within steels, in real-time, also in environments that mimic how the steel is used. This enabled researchers from KTH and Sandvik Materials Technology to find out why steels from Sandvik are more resistant to hydrogen embrittlement than other steels.

  • HYBRIT will de-carbonize the steel industry

    When the UN Climate Summit gathered the world's leaders in New York last fall, two Swedes were the talk of the town: Greta and "HYBRIT" - an initiative by SSAB, Vattenfall and LKAB that will make steel production fossil-free and substantially reduce CO2 emissions in Sweden. KTH plays an important role in what is called a revolution in steelmaking.

  • Recovered electronics reduce carbon footprint

    Waste from electrical and electronic equipment (WEEE) is estimated to grow to about 12 million tons by 2020 in EU, which makes it the fastest growing waste stream. By mixing recovered WEEE in metal production, the carbon footprint decrease considerably. WEEE also contains more than 30 % of plastics, which can be a useful source of chemical feedstock and energy.

  • Sustainable refrigerators thanks to magnetic materials

    Magnetic heat-pumps offer a low-energy demand and environmentally friendly alternative for the classical refrigeration industry. The process is called Magnetocaloric refrigeration and the Department of Materials Science and Engineering is working on developing materials based on cheap and less scarce metals like iron, manganese, arsenic, phosphorus and silicon.

  • Elastic "memory" metal achieved without relying on heat

    Elastic metal alloys are able to “memorize” their previous form after being subjected to temperature change. Now a new alloy has been developed which becomes elastic at room temperature.

  • Paper waste makes greener steel

    If the ideal sustainability project saves both the environment and money, and at the same time develops a research area, Osmet might be just that. Two of Sweden's largest basic industries join forces in an industrial and environmental win-win, where one's waste is processed into the other one’s raw materials. A project now entering its third step and made possible by, among others, researchers at KTH.

  • Stainless-steel slag treat acidic wastewater

    Slag from stainless-steel can substitute the use of lime to neutralise industrial acidic wastewater. This way part of the CO2 emissions derived by the extraction and processing of lime can be avoided, while reducing landfilling for stainless-steel producers.

  • Malin Selleby the first woman to get the Sefström Medal

    Malin Selleby receives the Sefström Medal for her work in Computational Thermodynamics. The Sefström Medal is awarded by The Swedish association of mining and metallurgical engineers* every 5 years since 1987 and this year it was time for the first woman to take place on the podium.

  • Borgenstam on prestigeous list

    Annika Borgenstam, Professor at Materials Science and Engineering, is among the 40 most powerful women in mining and steel, according to "Sveriges hårdaste lista".
