With a special insulated sintering chamber, a MICROWAVE OVEN can be used to make metal parts. The authors report being able to fuse wide range of powdered metals into small solid rings, tubes, & gears. obtaining fully dense bodies with improved mechanical properties compared to identical bodies sintered in conventional manner. Traditionally, a metal is compacted with small amount of binder & sintered at high T in a furnace - an energy-intensive process. The new method may offer fine microstructures & better properties at lower cost. Their microwave system consists of a ceramic tube surrounded by a ceramic fiber insulating blocks inside a 2.54-gigahertz oven. The sample is placed within the tube, where the atm. can be controlled & T can reach 1,300C as it is microwaved from 5 min to 1 hour |
