New class in summer semester 2020 at RWTH Aachen on Sustainable Materials Science and Green Metallurgy 

Synposis for the new class on Sustainable Materials Science and Engineering

This new course is about the emerging field of sustainable materials science and engineering. The course deals with two aspects of sustainability in this field. The first one is the sustainability of metallurgical processes and the downstream manufacturing chain, which we refer to as direct sustainability effects (e.g. Hydrogen based metallurgical reduction methods). The second one covers sustainability improvement, enabled through the use of advanced materials. We refer to this second branch as, indirect sustainability (e.g. the use of solar cell materials). The motivation for this class is the huge environmental impact of materials and metallurgy. The global production of metals and metallurgical products stands for the gigantic number of about 8% of the total energy consumption on the planet. It is also responsible for about 30% of all industrial CO2 equivalent emissions. These contribute as greenhouse gas to global warming. Therefore, this class tackles the basics materials science aspects of these question, and sheds light on which solutions metallurgy and materials engineering can provide in that context.

A very first introduction can be found here.

This is an introductory class about sustainable metals and metallurgy, a field that is also referred to as green metallurgy. 
Engineering materials and particularly metallic alloys have enabled technological progress over millenia. 
Metallic materials have a historic and enduring importance in our society. They have paved the path of human civilization with load-bearing applications that can be used under the harshest environmental conditions, from the Bronze Age onwards. Only metallic materials encompass such diverse features as strength, hardness, workability, damage tolerance, joinability, ductility and toughness, often combined with functional properties such as corrosion resistance, thermal and electric conductivity and magnetism. 
The high and accelerating demand for load-bearing (structural) and functional metallic alloys in key sectors such as energy, construction, safety and transportation is resulting in predicted production growth rates of up to 200 per cent until 2050. Yet most of these metallic materials, specifically steel, aluminium, nickel and titanium, require a lot of energy when extracted and manufactured and these processes emit large amounts of greenhouse gases and pollution. 
The huge success of metallic products and industries also means that they has an important role in addressing the current environmental crisis. 
The availability of metals (most of the elements used in structural alloys are among the most abundant), efficient mass producibility, low price and amenability to large-scale industrial production (from extraction to the metal alloy) and manufacturing (downstream operations after solidification) have become a substantial environmental burden: worldwide production of metals leads to a total energy consumption of about 53 exajoules (10^18 J) (8% of the global energy used) and almost 30% of industrial CO2-equivalent emissions (4.4 gigatons of carbon dioxide equivalent, Gt CO2eq) when counting only steels and aluminium alloys (the largest fraction of metal use by volume)
This lecture gives an introductory overview of methods for improving the direct sustainability of structural metals, in areas including reduced-carbon-dioxide primary production, recycling, scrap-compatible alloy design, contaminant tolerance of alloys and improved alloy longevity, for instance throgh better corrosion resistance. The lecture also discusses the effectiveness and technological readiness of individual measures and also show how novel structural materials enable improved energy efficiency through their reduced mass, higher thermal stability and better mechanical properties than currently available alloys.
