bhadeshia123 - Sustainability of metals & their role in a circular economy, 13102021

There are approximately 2 billion tons of extremely useful metals produced each year but their production is associated with the emission of large amounts of greenhouse gases and pollutants. The lecture is about pathways for the sustainable use of structural metals, with reduced carbon-dioxide emissions, recycling, scrap-compatible alloy design, contaminant-tolerance of alloys and improved alloy longevity. Also discussed is the efficacy and technological readiness of individual measures.
