| Summary: | Heat treatment is a process often used to improve product performance by increasing the
strength of material or other desirable characteristics. Silicon nitride (Si3N4) tool insert is known for
its attractive properties including high fracture toughness, strength and wear resistance at elevated
temperatures. Heat treating these inserts by post-sintering them for 15 minutes at 600°C using
conventional heating and hybrid microwave energy has prolonged tool life by 11-21% and 48-94%
respectively. Machining was performed on a T6061 Aluminium alloy rod for tool life analysis at three
different cutting speeds; 215, 314 and 393 m/min. Cost analysis is performed on these post-sintered
Si3N4 inserts and found that there are economical benefits in the tooling cost when compared with the
untreated Si3N4 inserts. |
