Flash x-ray. [Nondestructive testing of material that is moving or changing very rapidly]

Description: The complementary techniques of flash x-ray radiography (FXR) and flash x-ray diffraction (FXD) provide access to a unique domain in nondestructive materials testing. FXR is useful in studies of macroscopic properties during extremely short time intervals, and FXD, the newer technique, is used in studies of microscopic properties. Although these techniques are similar in many respects, there are some substantial differences. FXD generally requires low-voltage, line-radiation sources and extreme… more

Laser-generated stress pulses for material-response studies

Description: Experimental techniques for the generation of stress pulses of submicrosecond duration, in the form of uniaxial strain waves, were developed by absorbing the radiation from a Q-switched laser in thin films of liquids and solids resting on hard steel substrates. The experiments employed pulses of radiation at a wavelength of 1.06 ..mu..m, with a duration of about 30 ns at half maximum power and fluences from 8 to 13 J/cm/sup 2/. The stress waves produced in the steel substrates were measured by … more
