As sintering applications march toward a $30 billion global business, the models for sintering have progressed, but generally follow behind observation. Documentation of the steps needed to build to a quantitative and predictive theory are often missed. Sintering: From Empirical Observations to Scientific Principles partitions sintering applications and observations to show critical turning points required to establish modern sintering as a predictive science.
This book, written by the most cited author in his field, is laced with people, organizations, critical steps, and important formulations in a mixture of history, personalities, and applications. Exploring how insights in seemingly unrelated fields sparked progress, it is also a teaching tool to show where there is success, where there are problems, and how to organize teams to leapfrog to new applications or plateaus of use. Randall German's Sintering: From Empirical Observations to Scientific Principles is a platform for directly addressing the critical control parameters in these new research and development efforts.
Sintering professionals and researchers; product/process engineers; faculty, upper-level undergraduates, and graduate students of mechanical, materials, and metallurgical engineering.

or key reader for more than 20 journals and held several director positions, including two terms
with APMI, and served on the Fellows Awards Committee of two professional societies.
He has supervised 100 theses, published over 960 articles, 25 patents, and 16 books, including Mathematical Relations in Particulate Materials Processing (2008), Powder Metallurgy and Particulate Materials Processing (2005), Liquid Phase Sintering (1985), Sintering Theory and Practice (1996), and Powder Injection Molding - Design and Applications (2003). He has edited 19 books and co-chaired more than 30 conferences.
Professor German's research and teaching deal with the net-shape fabrication of engineering materials via sintering techniques as used in powder metallurgy, cemented carbides, and ceramics.
