DEVELOPMENT OF NEW HEAT-RESISTANT STEEL TO AVOID THE DETRIMENTAL Z-PHASE PRECIPITATION AT HIGH TEMPERATURES

摘要

In this research, a thermodynamic-designed alloy has been developed and casted. The new alloy, according to simulated data, shall not contain deleterious Z-phase at temperatures above 600°C. The excessive vanadium content in the alloy is responsible for not achieving a complete martensitic matrix after the heat treatment procedure.
