Title: Production of UT Reference Blocks Containing Artificially Introduced Defects

Abstract

Metallic blocks of Inconel 718 and Ti-6A1-4V alloys that contain artificially introduced defects of known type, size, shape and location were prepared to serve as calibration standards in ultrasonic inspection. The synthetic defects employed to serve as reflectors were all pertinent to the specific alloy systems used, i.e. compositional defects termed as 'dirty white' 'white spot' and 'freckle' for Inconel 718; 'hard-alpha' for titanium alloy. Furthermore, as a defect type common to all three materials, spherical voids of various sizes were also incorporated into these calibration blocks. The aim of this study is to introduce defects of known type and size into metallic blocks made of superalloy Inconel 718 and titanium Ti-6A1-4V alloy. The scope of the study entailed determination of the correct parameters for manufacturing processes involved. Based on the results of the preceding phases of this study, it was decided that the method of Vacuum Hot Pressing (VHP) was to be used in this project to manufacture the metallic block containing artificial defects.

  • The n-type silicon crystals of about 0.15, 0.9, and 10 ..cap omega.. cm (pulled material) and 120 ..cap omega.. cm (float-zone material) are exposed to 2--9-MeV electron beams at total integrated fluxes up to about 10/sup 18/ electrons/cm/sup 2/. The production rates of each complex defect in irradiated silicon are investigated. They are obtained from the condition of charge neutrality by using the experimental values of the resistivity as a function of bombardment dose. The electron energy dependence and the impurity density dependence of the production rate are determined for each complex defect. The results suggest that a configuration ofmore » the defect states at E/sub c/-0.3 eV may be associated with a phosphorus atom, and in the intrinsic region the two occupied and vacant states should be symmetrically located above and below the middle of the energy gap, respectively.« less
  • The elementary pinning force of thin Nb layers introduced as artificial pinning centers in Nb-Ti is theoretically investigated in the relatively low field region using the Ginzburg-Landau theory. It is found that the pinning energy comes from the kinetic energy due to the induced superconductivity in the Nb layers by the proximity effect. Hence, these layers act as repulsive pinning centers, while normal layers such as {alpha}-Ti do as attractive ones. The elementary pinning force depends sensitively on the coherence length in the Nb layers and is larger for the longer coherence length. This value is predicted to be largermore » than that of {alpha}-Ti layers in commercial Nb-Ti wires even in the case of short coherence length.« less
  • Migration of pre-characterized carbon dust in a tokamak environment was studied by introducing about 30 milligrams of dust flakes 5-10 {micro}m in diameter in the lower divertor of DIII-D using the DiMES sample holder. The dust was exposed to high power ELMing Hmode discharges in lower-single-null magnetic configuration with the strike points swept across the divertor floor. When the outer strike point (OSP) passed over the dust holder exposing it to high particle and heat fluxes, part of the dust was injected into the plasma. In about 0.1 sec following the OSP pass over the dust, 1-2% of the totalmore » dust carbon content (2-4 x 10{sup 19} carbon atoms, equivalent to a few million dust particles) penetrated the core plasma, raising the core carbon density by a factor of 2-3. When the OSP was inboard of the dust holder, the dust injection continued at a lower rate. Individual dust particles were observed moving at velocities of 10-100 m/s, predominantly in the toroidal direction for deuteron flow to the outer divertor target, consistent with the ion drag force. The observed behavior of the dust is in qualitative agreement with modeling by the 3D DustT code.« less
  • Radium-226 was added to lake 227 of the Experimental Lakes Area in August 1970 so that gas-exchange rates between the atmosphere and the lake could be traced by its gaseous daughter product radon-222. Although we expected the radium to remain in solution it did so for only about 1 month. An investigation to locate the radium after it left solution revealed that it was taken up on the bottom in the littoral zone. Further experiments indicated that it had adsorbed to the algal detrital material on the littoral sediment surface. Seasonal movement of this material could thus be monitored bymore » following the movement of the radium with time. (auth)« less
  • The modeling of ultrasonic Non Destructive Evaluation often plays an important part in the assessment of detection capabilities or as a help to interpret experiments. The ultrasonic modeling tool of the CIVA platform uses semi-analytical approximations for fast computations. Kirchhoff and GTD are two classical approximations for the modeling of echoes from plane-like defects such as cracks, and they aim at taking into account two different types of physical phenomena. The Kirchhoff approximation is mainly suitable to predict specular reflections from the flaw surface, whereas GTD is dedicated to the modeling of edge diffraction. As a consequence, these two approximationsmore » have distinct and complementary validity domains. Choosing between them requires expertise and is problematic in some inspection configurations. The Physical Theory of Diffraction (PTD) was developed based on both Kirchhoff and GTD in order to combine their advantages and overcome their limitations. The theoretical basis for PTD and its integration in the CIVA modeling approach are discussed in this communication. Several results that validate this newly developed model and illustrate its advantages are presented.« less
