文摘
- •
The NbC0.93 powder was processed by high-energy ball milling.
- •
The microstrain and dislocation density increase with milling time increase.
- •
The corresponding decrease in crystallite size with milling time was observed.
- •
The material exhibits the presence of two fractions after ball milling.
- •
The RTOF neutron diffraction data are suitable for accurate microstructure analysis.
