| Abstract Scope |
This work aims at Manufacturing of AISI H13 hot work tool steels with nano-inoculants by powder metallurgy and studying the effect of addition of nano-inoculants and heat treatments on the microstructure, the physical and mechanical propertiesof AISI H13 hot work tool steels. AISI H13 hot work tool steel is manufactured by powder metallurgy with the inoculation with Cu-coated Si3N4 nano particles and using Sn and Ni nano powders. The heat treatments are performed to harden the material by changing the structure from austenite to a fully hardened and tempered martensite. The results showed that VC6 is the most proper carbide that can be observed in the martensite matrix after hardening regime as the vanadium content of H13 tool steel is much sufficient to form more stable carbides. Tempered martensite with less fraction of eutectic carbides are observed in both H13 tool steel either without or with inoculation. |
