Abstract
Transient liquid phase bonding(TLPB) was employed to join ODS ferritic steel blocks using an amorphous inset material based on Fe-3B-5Si composition with high vacuum uni-axial hot press. The microstructure and mechanical properties were investigated. The TLPB ODS steel showed rather homogeneous distribution of the insert material elements at joined region, while Y-Ti-O precipitation and grain growth up to 20 μm occurred at the region. The TLPB ODS steel had a fairly good tensile strength, which was up to 90% of base material, at temperatures from room temperature to 700 °C. However, it showed poor elongation and impact fracture energy compared to base material, which is considered to be due to the existence of Y-Ti-O precipitate at bonding interface and large grained insert material.
