High Temperature Fracture Mechanisms in Metallic Matrix Composites Produced by Solidification Techniques

Abstract

Basic studies of solidification processing and high temperature deformation that have a critical effect on fracture in intermetallic materials have been conducted. A study was undertaken with the objective of assessing the correlation between point counting, image analysis and acid analysis, for the determination of the volume fraction of particulate reinforcement in MMCs. In order to illustrate the effects of reinforcement and matrix composition on the results, two different matrices (Al and Ni3A1) and two types of reinforcing particulates (SiC and TiB2) were selected for the present study.
