Influence of Titanium Compounds on Melting and Crystalline Temperature of Mold Powder

Abstract

Influence of TiN(0.5%~2.5%) and TiO2(1%~5%) on melting and crystalline temperature have been studied and analyzed in ferritic stainless steel containing titanium mold powder. The results show that with the increasing TiN content from 0.5% to 2.5%, the melting and crystallization temperature of mold power change between 1053~1082°C and 951~981°C respectively. With TiO2 content from 1% to 2%, the melting temperature is lower from 1066°C to 1047°C. As the content of TiO2 increasing to 5%, melting temperature increases obviously to 1077°C. TiO2 has less effect on the crystallization temperature of mold power.
