摘要

摘要:采用消失模铸造法制备了由Si3N4陶瓷棒和孪生诱导塑性(TWIP)钢基体组成的陶瓷-钢复合组织。显微组织分析表明，陶瓷棒与TWIP钢基体能形成良好而紧密的界面。对复合材料组织与TWIP钢基体的力学性能进行了比较。结果表明:与TWIP钢基体相比，其抗弯强度由388 MPa提高到805 MPa;讨论了退火热处理对这种新型复合材料抗弯强度的影响。

Discussion of ceramic bar reinforced TWIP steel composite structure

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.
