Machining of hot pressed alumina–boron carbide composite cutting tool
Source abstract
Abstract
Abstract Al 2 O 3 –B 4 C composites containing up to 40 vol.% of dispersed B 4 C particles were fabricated by hot-pressing and machined as cutting tools. This composite showed higher micro-hardness and toughness than monolithic Al 2 O 3 because of the restricted grain growth by the presence of hard B 4 C particles. Machining tests were conducted on a carbon steel work piece to evaluate the performance of the Al 2 O 3 –B 4 C cutting tool.
