文摘
- •
A Fe–Cr–Nb-based composite with TiB2 neutron absorbing ceramic was mechanically alloyed.
- •
A hard TiB2 core-soft Fe-based alloy mantel structure of powder particles was formed.
- •
The powders were canned into a Ti-tubing.
- •
HIP-ing of mechanically alloyed powders was conducted at 1150 °C/200 MPa pressure.
- •
The near-Ti and intermediate diffusional layers are observed within the HIP-ed samples.
