Investigatimg the influence of trace tantalum on the microstructure and mechanical properties of niobium microalloyed steels

Abstract: The global production of niobium-microalloyed steels is now a well-established industrial practice. Initially driven by experimental insights into niobium’s ability to refine steel microstructures during thermomechanical processing, this technology has become especially prevalent in low-alloy steels. An important aspect of niobium’s production is its natural association with tantalum, which Leia mais…
