In this paper the authors propose a new technology for high volume fraction ceramic/metal composites—pseudo-semi-solid thixoforging, based on metal semi-solid process combing with traditional powder metallurgy technology, and explain the differences with other technologies and characters in detail. At the same time the authors prepare the cup shells with high volume fraction Al2O3/Al composite by this technology. It proves that it is feasible for the high volume fraction ceramic/metal composites forming through metallographic analyses and three-point bending tests. The results show that the tough strength and degree of hardness of the samples with certain plasticity are high. It will play a very big role in accelerating the ceramics composites and high melt point materials being used in more fields and tamp the foundation for further studies of this technology.
