Times Cited Count:3 Percentile:18.02(Physics, Condensed Matter)Natural and synthetic single crystal diamonds (type Ia, Ib, IIa and IIb) have been characterized by measurements of the X-ray integrated scattering intensity, lattice parameter and diffuse scattering. We found that the lattice parameter is smallest for natural diamond and largest for the B-doped diamond. We measured the diffuse scattering for (400) Bragg reflection for the four types of crystals. The scattering intensity of the natural crystals diffuses asymmetrically to form a streak along the [100] direction parallel to the reciprocal lattice vector. These results suggest the existence of the nitrogen atom platelets on (100) plane in the natural diamond. We also found the diffuse streaks along the [00] direction for (400) Bragg reflection for the B-doped crystal, suggesting that boron atoms are likely to form precipitates on the (100) plane.

Small specimen test technology (SSTT) has been developed to investigate mechanical properties of nuclear materials. SSTT has been driven by limited availability of effective irradiation volumes in test reactors and accelerator-based neutron and charged particle sources, and it is very useful for the reduction of waste materials produced in nuclear engineering. In this study new bend test machines have been developed to obtain fracture behaviors of F82H steel for very small bend specimens of pre-cracked -CVN (Charpy V-notch) with 20 mm-length and DFMB (deformation and fracture mini bend specimen) with 9 mm-length and disk compact tension of 0.18DCT type, and fracture behaviors were examined to evaluate DBTT (ductile-brittle transition temperature) at temperatures from -180 to 250C. The effect of specimen size on DBTT of F82H steel was also examined by using Charpy type specimens such as -CVN, CVN and -CVN. In this paper, it also provides the information of the specimens irradiated at 250C and 350C to about 2 dpa in the capsules of 04M-67A and 04M-68A of JMTR experiments.
