Expert has successfully worked with a variety of industrial clients to develop bases for process and product development in solidification processing, deformation processing and heat treatment of Al alloys. Specific applications have been semi-solid metal (SSM) forming, deformation processing of Al alloys for packaging and the design of heat treatments to strengthen Al alloys.

He has formulated and conducted R&D programs for industrial and government clients in many areas of ferrous metallurgy, including the thermomechanical and heat treatment of steels, precipitation behavior in steels, high temperature oxidation and hot corrosion and steel grade selection. He has utilized expertise in characterization via light microscopy, electron microscopy and x-ray diffraction and thermodynamic modeling to perform this work.

He has extensive experience in performing all types of metal failure analysis, including failures associated with cast and wrought product. Specifically, he has performed failure analyses of Al and Cu alloy castings, steel components, weldments and solders joints for microelectronic applications. Expert utilizes an array of analytical and material characterization approaches that include light and electron optical fractographic characterization as well as mechanical testing, combined with an analysis of the operative stress and environmental systems to arrive at a useful failure analysis.
