Abstract: Material and product life cycles are based on complex value chains of technology-specific elements. Resource strategy aspects of essential and strategic raw materials have a direct impact on applications of new functionalized materials or the development of novel products. Thus, an urgent challenge of modern materials science is to obtain information about the supply risk and environmental aspects of resource utilization, especially at an early stage of basic research. Combining the fields of materials science… Show more

“…The present description of the methodology thus focusses on the essential features of the evaluation method and the decisions to be made that are specific to the case of the assessment of superalloys. The method is based on the Augsburg method of criticality assessment [35], but with a small modification concerning the sector competition index [36], which has recently been introduced. Firstly, it evaluates the relative supply risk of twelve elements contained in various Ni-based superalloys (Al, Ti, Cr, Fe, Co, Ni, Nb, Mo, Ru, Ta, W, and Re).…”

“…Rhenium has the highest value with 48 points, because it is also a component of a reforming catalyst used in the petrochemical industry. Lowest sector competition values are observed for Cr, Nb, and Fe with 20-24 points [36]. These are metals which are used mainly in the steel and steel alloying industry with a comparatively lower added value for each use.…”

“…On the other hand the life‐cycle and the durability of the materials has to match the desired application. [ 26 ] One option can be the use of self‐healing materials to enhance the period of use of functional materials. [ 27–28 ]…”

“…This depends on fluctuating raw material prices, past, present, and future industrial investments leading to mass production, and regular fluctuations in product supply and demand. Finally, the benefits originating from each of the substitution of CMs in these alternative technologies would require state-of-the-art criticality analysis [140], together with state-of-the-art life cycle assessments.…”
