With the view to improve densification behaviour and mechanical properties of ZrB2-SiC ceramics, three synthesis routes were investigated for production ZrB2, prior fabrication ZrB2-20 vol. % SiC via spark plasma sintering (SPS). Two borothermal reduction routes, modified with a water-washing stage (BRW) partial solid solution Ti (BRS), utilised, alongside boro/carbothermal mechanism (BRCR) uti...

Over the last decade attempts have been made to fabricate aluminum matrix composites (AMCs) reinforced with several ceramic particles. Aluminum reinforced with ZrB2 particles is one such AMC. The successful application of new kind of AMCs lies in the development of secondary processes such as machining and joining. Friction stir welding (FSW) is a relatively new solid state welding which overco...
