Abstract: The small community of physicists concerned with flash x-rays, short pulses of intense hard bremsstrahlung with photon energies exceeding hundreds of keV, is always on the lookout for new detector materials and protocols to diagnose such radiation pulses. Important parameters for the detector include rise time, sensitivity, size and cost. Silicon carbide has many of the right material properties for such a detector. In the exploratory test reported here, a high voltage SiC diode performe quite well, which suggests that success can be expected from a more extensive program that would find out what SiC is capable of in this application.

Abstract: The texture influence on the mechanical behavior during uniaxial tension was studied in AZ31 (Mg – 3 Al – 1 Zn in wt.%), one of the common wrought Mg alloys. Since three tensile samples were cut in 0°, 45°, 90° to the extrusion direction, the initial bar texture influences on the mechanical behavior differently. In-situ texture measurements were carried out using hard X-rays under loading condition. According to the initial texture loading results in a variation of the mechanical behavior (yield strength, ultimate tensile strength and strain hardening rate) and in different final textures. The different texture development in each sample relates directly to the activation of different deformation systems, which is strongly influenced by the initial texture
