Abstract:
For finished products, it is sometimes necessary to measure hardness with minimal surface disturbance, where the indentations should not be visible to the naked eye. Applied loads that meet this requirement are below 0.9807 N for common metals. [..]

Abstract:
Superalloys based on Ni, Ni-Fe, and Co are among the most used metallic materials for high-temperature applications due to their excellent strength, creep and corrosion resistance. Co-based superalloys, in particular, offer superior corrosion resistance compared to Ni-based counterparts, making them ideal for long-lasting components subjected to moderate static or cyclic loads at elevated temperatures.

Abstract:
Quantifying the emissions intensity of production at the product level is essential for assessing the environmental profile of high value-added steel products and supporting strategic decarbonization in the industry. A modular and systematic methodology enables CO₂ emissions calculation across Scope 1 and Scope 2 within a closed-loop BF-BOF (blast furnace – basic oxygen furnace) production cycle. [..]
