摘要： A stress corrosion crack test method for evaluating the stress corrosion crack susceptibility of a steel material in alcohol. The method includes filling a cell containing a uniaxial tensile test piece of the steel material with an alcohol solution containing carboxylic acid: 0.1 mmol/L or more and less than 40 mmol/L, chloride ions: 0.05 mg/L or more and less than 300 mg/L, and water: 0.1 vol. % or more and less than 5 vol. %. Additionally, the method includes applying a fluctuating stress at a frequency of 2.0×10−5 Hz or more and 2.0×10−2 Hz or less to the uniaxial tensile test piece in the tensile direction. The maximum stress being equal to or more than the yield strength and less than the tensile strength at a test solution temperature, and the minimum stress being 0% or more and 90% or less of the yield strength.

摘要： Aged deterioration of ferromagnetic construction materials is nondestructively evaluated by applying to an evaluating material a magnetic field whose magnetic field amplitude is rather low, distinguishing various lattice defects, and quantifying them separately. A method includes obtaining a stress-strain relation in advance by a tensile test, evaluating a minor hysteresis loop (reference minor loop) while applying an applied stress (σ) thereto, obtaining correlation between physical quantities for evaluating aged deterioration, obtaining a subject minor hysteresis loop (subject minor loop) by a tensile test, obtaining measured values of the physical quantities from the loop, and evaluating aged deterioration of the evaluating material from the measured values.

摘要： Disclosed herein are systems, devices and methods for stress-rupture testing selected materials within a high-temperature liquid salt environment. Exemplary testing systems include a load train for holding a test specimen within a heated inert gas vessel. A thermal break included in the load train can thermally insulate a load cell positioned along the load train within the inert gas vessel. The test specimen can include a cylindrical gage portion having an internal void filled with a molten salt during stress-rupture testing. The gage portion can have an inner surface area to volume ratio of greater than 20 to maximize the corrosive effect of the molten salt on the specimen material during testing. Also disclosed are methods of making a salt ingot for placement within the test specimen.

摘要： An apparatus for evaluating the mechanical properties of a material has a superconducting magnet that has a plurality of magnet windings arranged side by side in the direction of a longitudinal axis of the magnet. The interior of the magnet is provided with a vertical space and a horizontal space for housing a test specimen in alignment with its longitudinal axis and at right-angles to the longitudinal axis. The apparatus is also provided with a fitting so that the magnet can be attached in an orientation that is in alignment with a longitudinal axis of the vertical space, and can be rotated by 90 degrees in a plane that includes a longitudinal axis of the horizontal space to thereby be oriented in a second direction.
