The linear thermal expansion coefficient (CTE), heat capacity, and thermal conductivity, were investigated as a function of temperature for hot pressed ZrC and liquid phase sintered ZrC–Mo cermets. The ZrC and the ZrC–Mo cermets had the same CTE

Microstructure analysis and mechanical characterization were performed on ZrC–Mo composites with 20, 30, and 40 vol% Mo produced by hot isostatic pressing. The composites reached >98% relative density after processing at 1800 °C and 200 MPa for 1

Pressureless sintering of ZrC-Mo cermets was investigated in a He/H 2 atmosphere and under vacuum. A large density increase was observed for specimens with > 20 vol% Mo after heating at 2150°C for 60 min in a He/H 2 atmosphere. The increase in densi

The chemical compatibility of ZrC and Mo was investigated in carburizing and carbon-free environments at temperatures from 1700° to 2200°C. Heating in the carburizing atmosphere resulted in the complete reaction of Mo with C, while the carbon-free

A series of cemented carbide materials were prepared using a coextrusion process, followed by rapid omnidirectional compaction for complete consolidation. The coextrusion process allows the carbide and metal binder phases to be reengineered into spec

In an effort to improve the wear characteristics of petroleum drill bit inserts, a series of cemented carbide materials with a functionally designed cellular (FDC) architecture were fabricated by a coextrusion process. The FDC architecture characteri
