Abstract
Abstract A ceramic–steel composite structure which consists of Si3N4 ceramic bars and twinning-induced plasticity (TWIP) steel matrix was prepared using lost foam casting method. Microstructural analysis indicated that the ceramic bars and TWIP steel matrix can form favorable and tight interface. A comparison of mechanical properties between the composite structure and TWIP steel matrix was made. Results show that the bending strength increased from 388 to 805 MPa compared with TWIP steel matrix. The influence of annealing heat treatment on the bending strength of this new type of composite structure was also discussed.
期刊介绍：
Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
