Metallic materials produced by different metallurgical methods have enabled progress over a long period, and are currently facing severe limits set by sustainability. The accelerated demand for practically all metallic alloys in key areas such as infrastructure, energy, transportation, construction, etc. creates huge growth rates. However, the environmental challenge and impact for manufacturing metallic alloys are becoming vital importance. On the other hand, it is also a sustainability enabler through e.g. lightweight design, magnetic devices, and efficient turbines, while its primary production is not. In this case, sustainable metallurgy is the key issue for the further development of the manufacturing of engineering materials.
There are direct and indirect research activities to improve the sustainable metallurgy for the high efficient production of metals. Direct sustainable metallurgy refers to the higher extraction ratio of valuable elements through recycling from secondary production, and implementing more sustainable solutions along the value chain including CO2-reduced primary production. Indirectly sustainable metallurgy can refer to render efficient alloy design upfront more recycling-oriented and weight reduction in transportation. Another strategy of indirect sustainability could be the improved alloy longevity through corrosion protection, damage tolerance and repairability for a longer lifetime of product use.
In this docent lecture, Wangzhong Mu will attempt to provide a short overview of the research activities on sustainable metallurgy he performed in the past seven years after his PhD. He will start to talk about the direct sustainable metallurgy research regarding the valuable elements recovery from different metallurgical wastes using hydrometallurgical method, alloy preparation utilizing the metallurgical slag as a raw material by pyrometallurgical method, etc. Subsequently.
He will move to introduce the indirect metallurgy research regarding ultra-clean steel production by controlling motion behaviors of impurity particles, high entropy alloys preparation utilizing the low price ferroalloys, design and manufacturing the new grade duplex stainless steels with a longer service life working at intermediate temperature conditions, etc.
Finally, he will complete the lecture by discussing exciting future trends and opportunities for the development of sustainable metallurgy.
