Abstract

Current methods used to measure strain at high temperatures depend on undesireable attachments or indentations and are generally limited to temperatures below 1800 deg F. The objective of this effort is to develop, construct, and demonstrate an ultrahigh-temperature strain measurement system using unobtrusive thin material coatings applied to test samples as reference marks for optical strain monitoring. The contents of this report describe the development of a system capable of measuring strain on specimens at temperatures ranging from room temperature to above 2000 deg F.... High temperatures, Strain measurements, High-temperature coatings, Optical methods, Gage marks, Sputtering methods.

DEVELOPMENT OF RESISTANCE STRAIN GAGES USABLE UP TO 1600 F

Technical Report Graft, W H ; Colner, W H

Results of work on the development and testing of an electrical strain gage usable up to 1600 deg F are summa rized. An evaluation was made of two alloys in the system Fe-Cr-Al, Alloy B (Fe-25 Cr-7 1/2 Al) and Alloy D (Fe-20 Cr- 10 Al). The alloys were reduced to 0.001inch diameter wires suitable for strain sensitivity determinations and resistance stability tests. Gages of both Alloys B and D were tested in a grid configuration on base materials of Type 302 stainless steel (18-8), Titanium Alloy C 110M and Udimet 500 Alloy. Test temperatures up to 1400 deg Fmore »« less
RESEARCH ON STRAIN-AGEING, HARDENING AND SOFTENING OF METALS BY FATIGUE. Technical Summary Report for September 1957-February 1959

Technical Report

Previous work relating to the fatigue of aluminummagnesium alloys was extensively reviewed. Room temperature fatigue experiments were conducted to find ihe condition under which true fatigue limits occur in aluminum-magnesium alloys. In the solution-treated condition, these materials do not have fatigue limits, but in the as-extruded they do. Metallographic observations show that increasing magnesium content reduces the widih of slip marks (striations) and surface cracking which occur during fatigue. Cracks were observed in aluminum - 1% magnesium, and aluminum - 3% magnesium in as-extruded specimens remaining unfailed below the fatigue limit. Tensile experiments at - 196 deg C subsequent tomore »« less
RESEARCH ON HIGH-TEMPERATURE STRAIN GAGE ELEMENTS

Technical Report Jordan, C B

An attempt was made to find materials for use as strain gages at temperatures above 2000 deg F (1093 deg C). Five materials were investigated: silicon carbide, silicon, pyrolytic graphite, rutile, and gallium phosphide. The gage factors of these materials were measured in the temperature range of 25 deg C (77 deg F) to 750 deg C (1382 deg F). The gage factor of silicon carbide was found to be very small even at room temperature, and none of the other materials appeared to offer any possibility of retaining a useful gage factor at 2000 deg F. However, several resultsmore »« less
DETERMINATION OF THE EMISSIVITY OF MATERIALS. Quarterly Progress Report, July 1 through September 30, 1963

Technical Report Hayes, R J

A screening rig was constructed to enable preliminary evaluation of coating behavior at elevated temperatures and to avoid coating volatilization in the emittance rigs. Three materials have been tested to date, namely, Kennanmetals K-151A and K-162B and iron titanate. The Kennametals were found to be stable up to 1600'F and the iron titanate up to 2000 deg F. Emittance measurements were made for coatings of Kennannetals K-151A, K-182B, nickel-chrome spinel, calcium titanate, and iron titanate. Values obtained for the Kennametals ranged between 0.82 and 0.89 in the 800 to 1600 deg F temperature range and were in good agreement withmore »« less
GAS-COOLED REACTOR PROJECT QUARTERLY PROGRESS REPORT FOR PERIOD ENDING SEPTEMBER 30, 1959

Technical Report

; D = > 6 ; : 6 < 7 8 9 7 9sion theory calculation of the power-density distribution in the EGCR was made in order to reduce the uncertainties in the results of previous calculations. A comparison was made of calculated neutron flux distributions in seven-rod fuel clusters and the preliminary results obtained in the Physical Constants Test Reactor at Harford. Neutron flux ratios for the EGCR lattice cell were calculated for fuel enrichments of 2.0 and 2.6%. Studies were made of the power densities attainable in gas-cooled reactors operated with ceramic material as both fuel and moderator.more »« less
