WebJun 1, 2024 · The formation of Si-rich phase is induced by the rejection of Ti and Si into the residual liquid during the γ matrix formation. With the increase in Si content, the size distribution of (γ-γ′)... superalloy IN792 (in a Hf free modification) that shows excellent corrosion resistance but poor castability. The aim of this research program is to understand the cracking mechanisms and develop new alloy compositions that are less susceptible to cracking. Alloys such as CM247 that exhibit excellent castability were chosen as reference materials.
