Study on the Microstructure of Vanadium-Modified Tungsten High-Speed Steel-Coded SAE-AISI T1 Steel

The essential goal of this research is to evaluate the modification process on phase transformation, matrix chemical composition, and precipitated carbide types for modified SAE-AISI T1 steel their effects hardness values after optimum heat treatment conditions. This adopts alloying design strategy enhance one most important tools coded (T12001). Therefore, two enhancement processes took place through partial or total tungsten replacement. Investigated was first addition vanadium then carbon. Substitute 5 wt steel. % with 1 wt. vanadium, in carbon content, varied from 0 %. fulfill goals work, Thermo-Calc software utilized get following: (i) thermodynamic equilibrium information, (ii) expected microstructure, (iii) constituent volume fraction, (iv) composition. composition phases confirmed by scanning electron microscopy (SEM) equipped energy-dispersive X-ray (EDX). In addition, fractions different constituents were estimated using authenticated imaging analysis process. experimental findings variations eutectic carbides precipitated, e.g., MC M6C carbides, agree well calculated findings. Tungsten replacement without extra at traditional encourages formation instead M6C, M23C6, M7C3 carbides. carbon-modified contains more carbon, chromium, but less compared vanadium-modified Vanadium gamma-austenite. Hardness measurements emphasized that a promising material its use as tooling low content and, turn, produces cutting-tool materials economical cost.
