My research is in the area of materials science
and micromechanics, dealing mainly with the relation between macroscopic
properties and microstructure. Mechanical properties are of primary
concern, although thermodynamic properties, transport mechanisms
and electronic, optical and magnetic behaviors are of interest
also. Both theoretical (including computer simulation) and experimental
investigations are emphasized.
Current topics include atomic force microscopy
to examine shear bands, scratches, crazes and early stages of
precipitation and phase changes; impression testing using micron-sized
cylidrical indenters to determine adhesion, creep resistance,
viscosity, and the kinetics of stress relaxation: mechanical and
magnetic properties of amorphous metals and quasicrystals and
intermetallic compunds; spontaneous combustion processing of nearshaped
products; ELID sawing and griding, and friction and wear mechanisms
using scratch and indentation resistance measurements.
Most of my Ph.D. students went to industry: four
went to Xerox, three at MRL/ITRI in Taiwan, and one each at Kodak,
G.M., 3M, ATT Laboratory, Dow, Shell Development, Sandia, Naval
Research Laboratory, Inland Steel, United Technology, Philips
Electronics, Stoody and Gerson. Four of my students are in academia.
