文摘
- •
Investigations are carried out on In-situ TiB2/Al composites whose cutting performance hasn't been studied widely yet.
- •
Unlike conventional ex-situ SiCp/Al composites, there is no sign of pull-out or fractured particles on the machined surface.
- •
There are compressive and tensile stress in the machined surface which is also different from that of SiCp/Al composites.
- •
No obvious softening and hardening is found below the machined surface.
