Solidified Structure of Thin Walled and Complicated Titanium Castings during Vertical Centrifugal Casting Process

摘要：

Solidified structures of thin walled and complicated titanium castings during vertical centrifugal casting (VCC) process have been studied in this paper. The macro-structure and grAln size at different process schemes were observed by scanning electron microscope (SEM). The Alm of the present paper is to establish quantitative relationships between the grAln size of the casttitanium components and the casting wall thickness. The paper includes comprehensive investigation of the microstructure during the VCC process. The results show that the centrifugal rotational velocity has much bigger effect on the microstructure of thicker wall parts. The cooling rate of the castings has more effect on the grAln size distribution of the castings over the centrifugal rotational velocity.
