Spotlight on Research - Highlights of CAVS Contributions in PowderMet 2007

PowderMet is the largest international conference and exhibition of P/M (powder metallurgy) held in North America. This year the conference was held in Denver, CO on May 13-16. Seven employees from Materials Processing Group attended this conference. Also, sixteen CAVS employees wrote 22 papers which cover 12% of total presentations in the conference. Co-authors were collaborated from 16 other institutes as well as 5 other countries, which show a strong and global network of CAVS in P/M field. All of the participants from CAVS included: Mr. Paul Allison, Dr. Antonyraj Arockiasamy, Dr. Randall M. German, Dr. Philip Gullett, Dr. Youssef Hammi, Dr. Mark Horstemeyer, Mr. Bohumir Jelinek, Dr. Seong-Gon Kim, Dr. Seongjai Kim, Dr. Sungho Kim, Dr. Seong-Jin Park, Mr. Travis Puzz, Ms. Tonya Stone, Mr. Kyle Thompson, Mr. Wesley Trim, and Ms. Laura Turcker.
