Abstract
The fracture toughness parameters for nine tungsten carbide cobalt alloys has been determined. These alloys range in cobalt content from 3 to 15 wt. % and from 1.5 to 8 microns in tungsten carbide grain size. A wedge loaded double cantilever beam approach was used to obtain the GIC and KIC values for these high modulus low toughness materials. This was done in order to obtain the necessary displacement control such that a crack situation could be realized.
This paper is based on a thesis submitted by R. C. Lueth in partial fulfillment of the requirements for the degree of Doctor of Philosophy of Metallurgy, College of Engineering, Michigan State University. The work was conducted in the Hard Metals Research Section of the Carboloy (R) Systems Department, General Electric Company.
