Estimation of potential of steel scrap as secondary resource of alloy elements using dynamic input-output model based material flow analysis

Kentaro Takeyama

Tohoku University

Mr. Kentaro Takeyama is a master course student in Tohoku University. Studies about a dynamic material flow of steel and alloy elements.


Nickel (Ni) and chromium (Cr) are regarded as strategic metals and mainly used for production of alloy steels especially stainless steel. For sustainable steel production and strategic use of alloy elements, recycling of steel... [ view full abstract ]
