Sintering Behavior, Microstructure, and Mechanical Properties: A Comparison among Pressureless Sintered Ultra-Refractory Carbides
Figure 9
Fracture surface of HC10 after bending test at room temperature: abnormal grain which acted as critical defect, both the two surfaces of the bars are shown. After improving of the powder treatment, the flexural strength increased of about 100 MPa and decreased the standard deviation.
