In a recent study, an Osaka University research team demonstrated that cracks induced in composites of alumina (Al2O3) ceramics with titanium (Ti) as a dispersed phase could be healed at room temperature.
It appears that the domestic U.S. market for aluminum is stagnant-to-soft while the export price is stronger and trending up. Tariffs have reduced the amount of scrap being purchased by China, but other foreign markets have more than made up for the loss. Total U.S. exports increased 12% last year.
According to a report, Germany’s Thyssenkrupp plans to phase out CO2-intensive coke-based steel production and replace it with a hydrogen-based process by 2050. Along those same lines, ArcelorMittal intends to use hydrogen on an industrial scale in the steelmaking process for the first time. Not to be left out, Tenova and Salzgitter AG will cooperate on a concept for a significantly CO2-reduced steel production.
The Sparrows Point steel mill will be featured in a new long-term exhibit at the Baltimore Museum of Industry in 2021. The display will combine oral histories, artifacts and photos reflecting the 125-year history of steelmaking at the former home of Bethlehem Steel in eastern Baltimore County.
The Materials Processing Institute, a research and innovation center, joined a U.K.-wide project to support British manufacturing and steel jobs. SUSTAIN has been co-created by U.K. steel producers, universities and other supporting partners. Its goal is to generate around $45.5 million in projects over a seven-year period.
U.S. Steel was in the news recently when it expanded paid-leave benefits for nonunion employees and rolled out brand-new benefits like gender reassignment surgery coverage and adoption assistance. So, what’s the deal?
Steel rails have been the material of choice for railways since the first installation at Derby station in Britain in 1857. Today, scientists at the Institute of Railway Research at the University of Huddersfield (U.K.) have studied the relationship between heat treatment and railway service life.
According to WorldSteel, a global alliance of steelmakers, life-cycle assessment (LCA), measures how the manufacturing of a product – the extraction of raw materials and the use and the recycling of the product – impacts the environment. With that in mind, South Korea’s Posco is assessing the impact of steel manufacturing in terms of LCA.
This article discusses how new technology – particularly artificial intelligence – is impacting the world of steel manufacturing. As examples, Noodle.ai, an AI firm based in San Francisco, provided software systems to Big River Steel in Arkansas, and U.S. Steel is investing in automation and robotics.
Because of equipment improvements and material innovations – such as no-cement, colloidal silica, which offers optimal alkali resistance and bonding properties – contractors are installing monolithic refractories in areas of cement kilns once reserved for brick refractory.
