Improved performance in aluminium oxide tool inserts via post sintering using hybrid microwave energy

This research investigates the effect of hybrid microwave energy toward the enhancement of tool life in Al₂O₃ inserts. Post sintering was done using conventional and hybrid microwave sintering at 600°C for 15 mins and compared the findings with the original available commercial inserts. Mechanical t...
