Welcome to the website for the MMC
Hammer Group, composed of Edward Barnard, Elizabeth Hager, Jenny
Lichter, and Kevin McComber. This project is part of Course 3.082
- Materials Processing Laboratory at the Massachusetts Institute of
Technology. We are all undergraduates majoring in Materials
Science and Engineering and are either juniors or seniors. Our
advisor on this project is Jessada Wannasin, a PhD candidate at M. I. T.
We hope you enjoy learning more about the production, benefits, and applications of Metal Matrix Composites. If you have any questions or comments about our research you may contact us at mmchammer@mit.edu

"High
Performance Metal Matrix Composites
(MMCs) for Sporting Goods"
"Metal matrix composites are materials consisting of two or more materials, one of which is a metal, in which tailored properties are achieved by systematic combinations of different constituents. Several MMC fabrication processes are in use today, including powder metallurgy, spontaneous infiltration, and pressure infiltration. An infiltration process utilizing centrifugal force has been developed at MIT. A laboratory centrifuge has been used to study the fundamentals of the infiltration process and make small samples. Results from this study have shown that this process is a promising commercial process. The objective of their project is to choose materials parameters and further develop the centrifugal infiltration process to make actual parts designed for a specific application. A possible application is a golf club face where specific hardness, strength and elastic modulus can be optimized to get the best performance. For example, and MMC face made by Wilson, consisting of tungsten carbide, cobalt and nickel chromium, claims to offer "deal accuracy and remarkable distance." The fabrication challenges of this work are to establish the process to make shaped ceramic preforms, and the technique to carry out the infiltration process. Performance metrics will be determined by the specific application."
