David Laughlin is the ALCOA Professor of Physical Metallurgy, a Professor of Materials Science and Engineering and also has a courtesy appointment on the Electrical and Computer Engineering Department of CMU. He was the Editor of Metallurgical and Materials Transactions from 1987-2016. David is a graduate of Drexel University (1969) and the Massachusetts Institute of Technology (1973). He is the recipient of the G. T. Ladd Teaching Award (1975) and the B. R. Teare Award for Excellence in Engineering Education (1999). He is a co-recipient of the outstanding research award in 2003 in the College of Engineering and is Fellow of ASM International as well as TMS.  He has authored more than 475 technical publications in the field of phase transformations, physical metallurgy and magnetic materials.  He is the co-author of “Introduction to the Materials Thermodynamics” as well as co-editor of the three volume Physical Metallurgy.



Ph.D., Massachusetts Institute of Technology


The research interests of David E. Laughlin have centered on the investigation of phase transformations and the structure of materials by means of transmission electron microscopy. He has studied spinodal decomposition and ordering processes in several aluminum, copper and nickel based alloys as well as in III-V compounds by detailed analysis of their microstructure as well as electron diffraction patterns. Since 1986 he has been investigating the magnetic properties and microstructure of soft magnets (HITPERM), hard magnets (FePt and CoPt) and magnetic thin films for recording media and heads. Recently he has been exploring topological materials.
