- 3 national invention patents granted
- 3 papers published in Journal of Materials Processing Technology
Thin-Walled Ti-Steel Composite Pipes
An innovative composite forming process was developed to fabricate thin-walled titanium-clad steel pipes:
- Pipe diameters ranging from 24 mm to 133 mm (Ti wall : Steel wall = 1:3)
- Excellent interfacial bond quality with shear strength > 100 MPa
- Combining titanium's corrosion resistance with steel's structural strength
