In carrying out a medical study of the effectiveness of a new treatment, the “gold standard” is the randomized double-blind, placebo-controlled study. This type of medical trial is specifically geared to human participants, whose human minds might otherwise influence the outcome.
The human brain is rather good at recognizing a large variety of objects: a chair, a ball, a hang-glider, etc. Recognition is usually almost instantaneous, assuming one learned at some point in the past what each of these objects is called.
Shimadzu Scientific Instruments and Oklahoma State University (OSU) joined forces to establish The College of Engineering, Architecture and Technology’s (CEAT) Mechanical and Physical Properties Testing Lab. The new lab is part of the ExxonMobil Testing Laboratory in the new ENDEAVOR facility on OSU’s campus in Stillwater, Okla. Equipped with a collection of Shimadzu’s materials-testing instruments, the space will allow students to characterize materials by utilizing an array of scientific techniques.
Element Materials Technology (Element) acquired Cleveland, Ohio-based Orbit Industries Inc. (Orbit), a Nadcap- and ISO 17025-accredited laboratory and provider of nondestructive testing (NDT) services to aerospace primes and Tier 1 suppliers. With over 30 prime approvals, Orbit specializes in ultrasonic, liquid penetrant, magnetic particle and chemical processing for raw materials and semi-finished and finished products, including landing-gear components, airfoils and aluminum wheels. Orbit also operates out of four other satellite inspection facilities across Ohio, Pennsylvania and New York.
The microstructure of a material represents its fundamental properties, and most heat treatments are performed to tailor these properties to a specific need. Good metallographic preparation allows faster and more-accurate quality control – whether a microstructural inspection or performing specific tests such as case-depth analysis.
Wisconsin Oven Corp. shipped six propane-gas-fired, enhanced-duty walk-in ovens to a material-testing laboratory. The batch ovens, which will be used for hydrogen embrittlement relief of various parts, have a maximum operating temperature of 500°F and work-chamber dimensions of 8 feet wide x 4 feet long x 4 feet high. They were designed with the capacity to heat 1,020 pounds of steel and 220 pounds of a load cart from 70°F to 480°F within 60 minutes when loaded.
Solar Atmospheres of Western PA continued its merit status for Nadcap Nondestructive Testing for penetrant inspection. Solar Atmospheres specializes in Method A (water washable) Fluorescent Penetrant inspection and is able to accommodate parts of varying sizes in their NDT cell. The company has its own in-house Level 3 inspector as well as six Level 2 inspectors and one Level 1 inspector. Solar Atmospheres is on Boeing’s approved supplier list and typically inspects three linear miles of vacuum stress-relieved weldments for the 787 Dreamliner per month.
