can powder metallurgy process produce composite material?

Answer 1

Yes. Although the process is called "powder metallurgy," it can actually also incorporate powered materials that are nonmetallic, such as ceramics. These materials are compacted into the required shape and then sintered (heated in a controlled environment) to bond the powdered particles into a solid mass. The material properties can be tightly controlled by varying the composition of the powdered mix, and the resulting product is indeed a composite material.
