SCOPE OF TESTINGHURST METALLURGICAL performs metallurgical testing and evaluation to the various ASTM, AMS, ASME, AWS, Military and other industry recognized standards. The following is a partial listing of the approved services:
Metallurgical ServicesFailure Investigation: Wreckage analysis, visual inspection, fractographic evaluation, fracture mode determination, examination of metallographic sections, tensile, impact, and hardness testing, data analysis and technical report preparation.
Metallographic Evaluation: Microstructural analysis of: carbon and alloy steels, cast irons, titanium alloys, copper alloys, nickel base alloys, stainless steels, aluminum alloys fabricated by welding, forging, casting or machining.
Testing/evaluation for: microstructure of graphite in cast iron, grain size, discontinuities/defects, inclusion content/microcleanliness, coating thickness, case depth, decarburization/case-carburization, intergranular attack, microetch, and macroetch.
Inspection: Surface condition evaluation of materials affected by design, manufacturing, and/or service.
Mechanical TestingWeld Evaluation: Weld inspection, welding and brazing procedure qualification testing, tensile, bend, impact, and hardness testing.
Quality Control Testing: Tensile/tension, compression, hardness (Brinell, Rockwell, Vickers, Knoop). Shear and Charpy V-notch impact testing.
Chemical Analysis / Alloy IdentificationOES analysis: of carbon and alloy steels, tool steels, austenitic ferritic martensite, and precipitation-hardening stainless steels, brass, bronze, copper alloys, pure aluminum, and aluminum alloys, nickel base alloys and tin/lead alloys.
