Expert has gained extensive experience in the uses of ferrous metals and alloys (carbon and alloy steel, high strength steel, structural steel, heat resistant steel), non-ferrous metals and alloys, superalloys, stainless steels (austenitic, ferritic, martensitic, and precipitation hardening grades), tool steels, and high-alloy steels. He has worked with flame and plasma spraying, metal plating with chromium and nickel, composite materials, and gear materials. He is conversant with ASTM, ASME, ANSI and international materials codes and standards for plates, sheets, shapes, tubing, bars, forgings and castings.

Expert knows and has applied the following processes: annealing and normalizing, austenitizing, quenching, tempering, stress relieving, age hardening, laser heating, cold treatment, and case hardening. His case hardening experience includes carburizing, flame hardening, and induction hardening.


Expert's ferrous and non-ferrous alloys casting experience includes sand casting, permanent mold casting, investment (lost wax or precision) casting, die casting, centrifugal casting, and lost foam casting. He is familiar with casting flow, solidification and defective conditions.

Expert has done failure analyses of metal products. His methods include metallurgical laboratory evaluations for the mode, sequence and cause of failure; fracture examination (fractography); and accident site examination. He uses these methods, plus metallography and microscopy, to study chemical composition and mechanical properties, metal overload, fatigue and corrosion, and hydrogen cracking or embrittlement. He provides expert witness testimony on metal product failures.

Expert is an expert in the application of welding processes, and in welding metallurgy, whether dealing with ferrous or non-ferrous metals and alloys. He is cognizant of welding codes, standards, and procedures promulgated by the AWS Structural Code, ASME Boiler and Pressure Vessel Code, and the military; with preheating and post-heating requirements; and with welding materials control methods. He has performed welder training, and reviewed weldment designsfor produceability. He is familiar with weld defects and detection methods, and with ways to improve quality and productivity. Specific methods within his purview include shielded metal arc welding, flux-cored arc welding, gas metal arc welding, gas tungsten arc welding, submerged arc welding, electroslag welding, and laser welding.

Expert has trained and gained application experience in ASTM, AWS, ASME and military NDE standards and procedures, as well as in NDE personnel qualifications and training requirements promulgated by ASNT, AWS and ASTM. He uses magnetic particle, liquid (dye) penetrant, ultrasonic, and radiographic testing methods, including x-ray and gamma-ray testing.

Expert has developed, documented, and implemented quality programs. He can provide the following supports: Total Quality Management Systems; quality system auditing; quality improvement and process control studies; statistical process control training and implementation; quality system requirements to MIL-I-45208, MIL-Q-9858, ASME Boiler and Pressure Vessel Code, API-QI Offshore Cranes, and the ISO 9000 Series; structural and mechanical design reviews, gage calibration system, material identification and traceability control, and supplier quality system and auditing.


Expert has experience in welded fabrication; conventional machining processes; press, die and impact forging; metal sawing, cutting, and shearing; metal rolling, forming, bending, stamping, and extruding; metal tube drawing; seamless tube production; abrasive blasting with sand, grit, glass beads, and vapor; and shot peening. He is knowledgeable of conventional available manufacturing facilities and practices.


Expert can provide support in testing for tensile and yield strength, hardness (Rockwell, Brinell, Vickers, Knoop, microhardness, and scleroscope), impact resistance (Charpy V-notch) and toughness, fatigue, creep, formability, low temperature properties, and wear resistance. He can provide microstructural examination of the material in question.


Expert has experience with steel and stainless steel corrosion, iron and steel rusting, atmospheric corrosion, galvanic corrosion, stress corrosion, and with an assortment of protective coatings.


Has evaluated numerous material failures to establish mode and cause of failure (e.g. welds, gears, shafts, and fractures).He has provided selection of materials for various industry applications and products.Has performed development and training of clients in implementation of quality systems to meet customer or industry requirements He has established appropriate compositions and properties of castings for service in various products, including acceptability for weldments.He has participated in several product liability and personal injury litigation cases, providing supporting engineering information and court testimony.
