|
Expert has 20 years of experience in providing effective forensic materials failure analysis. His knowledge enables him to apply the data obtained from auger electron spectroscopy, X-ray nondestructive testing, chemical analysis, metallography, scanning electron microscopy, and energy dispersive X-ray analysis to the task at hand. To fully use the results from the scanning electron microscope, Expert has a comprehensive understanding of fracture surface topographies and how they are related to the underlying microstructures. His extensive background in metallography and microstructure analysis, including quantitative metallography of many different metals, enables him to determine the effect underlying microstructures of materials on the surface topographies.

Expert uses data from gathering methods combined with hands-on experience and technical understanding of materials processing. He has worked with steel annealing, steel finishing material, steel forming, steel foundry, steel heat treatment, steel hot forging, steel machining, steel manufacturing, steel processing, steel product quality assurance, steel quenching, steel selection, steel swedging, steel tempering, welding process, bainite, hot-rolled steel, hydrogen-induced steel cracking, steel corrosion, metal alloy, metal component fabrication, metal contamination, metal drilling, metal fabrication, metal failure, metal failure analysis, metal forming, metal grinding, metal machining, metal mechanical behavior, metal milling operation, metal polishing, metal processing, and metal turning to determine the cause and origin of the failure and ways of preventing similar future failures.

|
As a routine part of a failure analysis, Expert uses fracture mechanics to ascertain the magnitude of the stresses present. He develops data necessary to perform fracture mechanics from the use of common metallurgical tools such as visual examination, metallography, scanning electron microscopy, Auger analysis, energy dispersive X-ray analysis, and micro-hardness testing. He finds that fracture mechanics are very useful in failures involving fatigue. He will use fracture mechanics when no other methods are available for determining the fracture toughness of a material. He has used fracture mechanics in the evaluation of both metals and non-metals.

Failure analysis of metals is a normal part of Expert's work. His extensive experience as a consultant and with manufacturing companies has given him unique insight into heavy metals failure and the design and manufacturing changes that can be done to eliminate failures in the future. To accurately determine the cause of failure of a metal, he uses all of the techniques necessary, such as metallography, chemical analysis, mechanical testing, macro-etching, metal alloy, metal contamination, metal failure, metal mechanical behavior, metal property, metallurgical testing, scanning electron microscopy, surface analysis, welding failure analysis, steel heat treatment, welding quality, welding testing, and surface analysis. This information is then used by Merlin, along with fracture mechanics and information about the processing of the metal to determine the cause of metal failure. Examples of metal processing include electroplating, steel heat treatment, steel tempering, steel annealing, sheet metal forming, sheet metal fabrication, metal processing, metal forming, metal grinding, metal machining, metal turning, and the environment that the metal was used in.

Expert has extensive experience in the heat treatment of iron and steel. His experience includes spheroidized annealing, inter-critical annealing, pearlitic annealing, normalizing, carbonitriding, carburizing, quenching and tempering, steel tempering, mar-quenching, austempering, and stress relieving. His experience includes the planning, equipment selection, construction supervision, operator training, and procedure manual preparation for new steel heat treating facilities.

|
|
Expert uses metallography as the primary tool in the practice of metallurgical engineering. He uses metallography to determine the microstructures of both ferrous and nonferrous metals. He uses metallography as the critical tool in determining the correct steel heat treatment, steel annealing, steel quenching, welding process, welding quality, grain boundary determinations, nonferrous metal annealing, microstructure analysis, phase relationships, and quantitative metallography using Optimus image analysis, metal-related quality assurance, and metal-related quality control.
|
|
|
Expert's practice of metallurgical engineering as a registered professional engineer has been in physical and mechanical metallurgy of ferrous and nonferrous metals. His experience has been in providing metallurgical engineering support for manufacturing, manufacturing engineering, quality control, and design engineering. He has also been involved in modifying and developing manufacturing processes to achieve the desired metal characteristics in the finished product.
|
|
|
One of Expert's stronger fields is relating the structure of metals and alloys to the physical and mechanical behavior of the materials during production and final use. He obtains the metal and alloy structural data by the use of metallography. This data is in turn related to the composition, hardness, fracture toughness, fatigue properties, and mechanical strength of the metal or alloy. This information is in turn used to determine how and why products fail during use, through the application of fracture mechanics, metal failure analysis, and forensic materials failure analysis.
