Phosphate Exploration and Property Evaluation in Southeastern Idaho, Illustrated by the Dry Valley Area

Spalding, James Simon 01 May 1974 (has links)
The western phosphate field produced about 15 percent, in 1970, of the nation's domestically consumed phosphate rock and contains an estimated 58 percent of the nation's indicated phosphate reserves. The central portion of the western phosphate field, which contains the Dry Valley area of southeastern Idaho, encompasses the greatest amount of mineable phosphate reserves in the smallest geographic area within the western field. Exploration of properties in the area should follow an orderly sequence of literature search, area reconnaissance, detailed target appraisal, and detailed three-dimensional sampling to effectively evaluate each property. Present exploration techniques include topographic analysis, vegetative investigation, profile drilling patterns using a portable rotary-table drilling rig, geophysical logging of the drill holes including gamma-radiation logs, neutron logs, temperature gradient and differential temperature logs, and bulk density logs, trenching, tunneling, and test mining. The economic analysis of exploration programs embodies bookkeeping, project cost forecasting and an economic analysis of alternate methods of exploration. The evaluation of individual phosphate properties includes such variables as geology, mining characteristics, alternate concepts in reserve calculation, transportation and governmental policies. The structural geology of the Dry Valley area is less complex than the structural geology of other phosphate deposits in the western phosphate field. Yet most structural features outlined by drilling in Dry Valley occur elsewhere in the western phosphate field. The stratigraphy of the Phosphoria Formation and its Meade Peak Phosphatic Shale Member is simple and correlatable throughout southeastern Idaho through the use of gamma-radiation logs. The history of land acquisition and property evaluation by FMC in Dry Valley covers a relatively short eight-year period. Future plans for companies operating in the western phosphate field include trading and selling of properties to build mineable units covering large volumes of the estimated 300,000,000 tons of economically surface extractable ore in the Dry Valley vicinity.

Processing-Structure-Property Correlation for Additively Manufactured Metastable High Entropy Alloy

Agrawal, Priyanshi 08 1900 (has links)
In the present study both fusion based - laser powder bed fusion (LPBF), and solid state - additive friction stir deposition (AFSD) additive manufacturing processes were employed for the manufacturing of a metastable high entropy alloy (HEA), Fe40Mn20Co20Cr15Si5 (CS-HEA). A processing window was developed for the LPBF and AFSD processings of CS-HEA. In case of LPBF, formation of solidification related defects such as lack of fusion pores (for energy density ≤ 31.24 J/mm3) and keyhole pores (for energy density ≥ 75 J/mm3) were observed. Variation in processing conditions affected the microstructural evolution of the metastable CS-HEA; correlation between processing conditions and microstructure of the alloy is developed in the current study. The tendency to transform and twin near stress concentration sites provided excellent tensile and fatigue properties of the material despite the presence of defects in the material. Moreover, solid state nature of AFSD process avoids formation of solidification related defects. Defect free builds of CS-HEA using AFSD resulted in higher work hardening in the material. In summary, the multi-processing techniques used for CS-HEA in the present study showcase the capability of the AM process in tailoring the microstructure, i.e., grain size and phase fractions, both of which are extremely critical for the mechanical property enhancement of the alloy.

Värderingars tillförlitlighet Värderingars tillförlitlighet / Reliability of Evaluations – An analysis of evaluation methods and internal contra external evaluation.

Fors, Sebastian January 2014 (has links)
Denna uppsats behandlar svenska börsnoterade fastighetsbolags tillvägagångssätt att värdera sitt fastighetsbestånd. Både när det kommer till metod och typ av värdering (graden av intern kontra extern). Vidare undersöks faktorer som står till grund för dessa och hur företagens värdering har förändrats sen en kortare tid tillbaka. Uppsatsen kombinerar analyser av finansiella årsredovisningar från svenska börsnoterade fastighetsbolag med ett par kvalitativa intervjuer med några av de högst respekterade och uppsatta personerna i fastighetsvärlden. Analyserna visar på att en majoritet av fastighetsbolagen använder en hög grad extern värdering tillsammans med avkastningsbaserade värderingsmetoder. Även en förändring av fördelningen mellan intern och extern värdering under de senaste fyra åren konstateras och reflekteras över. I intervjuerna jämförs bland annat interna och externa värderingars riktighet och trovärderighet ur två väldigt olika perspektiv. Här tas även problematik upp och skillnader i teori och praktik. / This paper deals with public Swedish property companies way of evaluating their property portfolio. Both when it comes to the valuation method and the type of the evaluation (rate of internal contra external). Further, factors behind these choices and how the evaluation have changed over a shorter time period. The thesis combines analysis of financial reports combined with qualitative interviews with some of the most respected and exalted people of the real estate world. The analysis shows that a majority of the property companies uses a high rate of external evaluation together with a yield method. Also a change in the ratio of internal and external evaluation during the last four years is found and reflected upon. In the interviews the correctness and reliability of internal and external evaluations are compared from two very different perspectives. Problems and differences between theory and practice are brought up here as well.

Materials selection and evaluation of Cu-W particulate composites for extreme electrical contacts

Watkins, Bobby Gene, II 21 January 2011 (has links)
Materials for extreme electrical contacts need to have high electrical conductivity coupled with good structural properties. Potential applications include motor contacts, high power switches, and the components of electromagnetic launch (EML) systems. In particular, the lack of durability of these materials in rail components limits practical EML implementation. These rails experience significant amounts of Joule heating, due to extreme current densities, and subsequent thermally-assisted wear. New more durable materials solutions are needed for these components. A systematic materials selection study was executed to identify and compare candidate materials solutions. Several possible candidate non-dominated materials as well as hybrid materials that could potential fill the "white spaces" on the Ashby charts were identified. A couple potential candidate materials were obtained and evaluated. These included copper-tungsten W-Cu, "self-lubricating" graphite-impregnated Cu, and Gr-W-Cu composites with different volume fractions of the constituents. The structure-property relations were determined through mechanical and electrical resistivity testing. A unique test protocol for exposing mechanical test specimens to extreme current densities up to 1.2 GA/m2 was developed and used to evaluate these candidate materials. The systematic design of multi-functional materials for these extreme electrical contacts requires more than an empirical approach. Without a good understanding of both the tribological and structural performance, the optimization of the microstructure will not be quickly realized. By using micromechanics modeling and other materials design modeling tools coupled with systematic mechanical and tribological experiments, the design of materials for these applications can potentially be accelerated. In addition, using these tools, more complex functionally-graded materials tailored to the application can be systematically designed. In this study, physics- and micromechanics-based models were used to correlate properties to the volume fraction of the constituents of the evaluated candidate materials. Properties correlated included density, elastic modulus, hardness, strength, and electrical resistivity of the W-Cu materials.
