Mechanical Properties
Microbac Laboratories can impose loads on materials up to 60,000 lbf. for determination of mechanical properties, including tensile, compression, shear, and bearing strengths. Tests can be conducted at temperatures ranging from 0°C to +175°C.
Metallographic Evaluation
Microbac Laboratories Hauser Division provides detailed studies of materials to magnifications of 2000x. Microbac can provide Nomarski interference contrast objectives to evaluate precipitates, microstructural changes, and other features. Bright field and dark field lighting provide suitable contrast for assessing microscopic features that are not readily discernible using only bright field lighting.
Microbac also has the capability to determine heat treatment response, grain size, inclusion count, secondary phases, and corrosion effects. We analyze diffusion phenomena, welds, weld heat affected zones, and brazed junctions. Microbac also performs cross-sectioning for hardness depth, coating thickness, dimensional verification, etc.
Corrosion Effects and Fracture Analyses
Using metallography and scanning electron microscopy, Microbac can assess corrosion from outdoor exposure, galvanic attack, intergranular effects, high-temperature oxidation, salt spray exposure, and buried, offshore, and soil environments. We also have the ability to assess microbiological corrosion.
Metal fractures are evaluated by scanning electron microscope, and energy dispersive X-ray spectroscopy. Microbac can provide an accurate understanding of fracture initiation and propagation.
Hardness Evaluations
Microbac Laboratories has microhardness, superficial hardness, and Rockwell hardness equipment to establish the condition of metals and can determine heat treatment effectiveness, including softening due to temperature exposure.
