Available in PDF, EPUB and Kindle. Book excerpt: This project was concerned with an attempt to find materials for use as strain gages at tem peratures above 2000 F (1093 C). Five materials were investigated: silicon carbide, silicon, pyrolytic graphite, rutile, and gallium phos phide. The gage factors of these materials were measured in the temperature range of 25 C (77 F) to 750 C (1382 F). The gage factor of silicon carbide was found to be very small even at room temperature, and none of the other mate rials appeared to offer any possibility of re taining a useful gage factor at 2000 F. How ever, several results which may well be of prac tical value were obtained: the usefulness of silicon as a strain gage was extended to about 650 C (1202 F) by a new contacting process, silicon carbide was found to be a good tempera ture sensor over a wide range of temperature, and rutile was found to be a good oxygen sensor over a fairly wide range of elevated temperature.

This book was released on 2018-07-02 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was done on the electrical resistance of materials that are potentially useful as resistance strain gages at high temperatures under static strain conditions. Initially a number of binary alloys were investigated. Later, third elements were added to these alloys, all of which were prepared by arc melting. Several transition metals were selected for experimentation, most prepared as thin films. Difficulties with electrical contacts thwarted efforts to extend measurements to the targeted 1000 C, but results obtained did suggest ways of improving the electrical resistance characteristics of certain materials.

Available in PDF, EPUB and Kindle. Book excerpt: A summary is presented of a research program aimed at the improvement of high-temperature strain gages of the electrical resistance type. Potential ceramic and metal components were evaluated and a gage was devised that was based on these evaluations. This gage (NBS 5B) was flexible and easy to install; however, it lacked resistance stability at higher temperatures. In an attempt to minimize this deficiency, ceramic cements were developed that showed greater electrical resistivity than had been previously observed in the range 800 to 1800 degrees Fahrenheit; also, a technique was devised for increasing the resistance to ground by applying a fired-on ceramic coating to the grid of a specifically developed unbacked gage. A study was made of the cause of the erratic response of cemented gages that had not been preheated prior to use. There were strong indications that the erratic response was caused mostly by the rapid decrease in resistance that accompanied structural changes in the cement.

Available in PDF, EPUB and Kindle. Book excerpt: Das vorliegende Buch ist ein umfassendes grundlegendes Kompendium über Dehnungsmessstreifen (DMS) und ihre Anwendung in der Materialwissenschaft und Werkstofftechnik sowie in allen Bereichen des Ingenieurwesens. Es deckt sowohl die theoretischen als auch die praktischen Aspekte der Spannungsanalyse mithilfe von Dehnungsmessstreifen ab. Ein historischer Rückblick auf die Erfindung und Entwicklung von DMS fasst das "Wer, Wann und Wie" zusammen. Die umfassende Bibliographie führt zu zusätzlichen Hintergrundinformationen. Besonderes Augenmerk gilt der Spannungsanalyse zur Bestimmung der mechanischen Eigenschaften, der Tragfähigkeit und der Gebrauchstauglichkeit von Bauteilen sowie zur Planung von Monitoring und Inspektionen. Die richtige Planung und Auswertung von Messungen und die Algorithmen zur Ermittlung von Spannungen werden aufgezeigt und die Interpretation von Ergebnissen erläutert. Dabei schöpft der Autor für die praxisorientierten Beschreibungen der Messprinzipien, der Messanordnungen und der Versuchsreihen aus seinem reichen Erfahrungsschatz. Das Buch enthält eine Anzahl realer Anwendungsbeispiele mit detaillierten Anleitungen, die als Vorbilder für die Lösung ähnlicher Aufgaben betrachtet werden können.

Book Synopsis Ceramic Strain Gages for Use at Temperatures Up to 1500 Celsius by : National Aeronautics and Space Administration (NASA)
Download or read book Ceramic Strain Gages for Use at Temperatures Up to 1500 Celsius written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-05-29 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indium-tin-oxide (ITO) thin film strain gages were successfully demonstrated at temperatures beyond 1500 C. High temperature static strain tests revealed that the piezoresistive response and electrical stability of the ceramic sensors depended on the thickness of the ITO films comprising the active strain elements. When 2.5 microns-thick ITO films were employed as the active strain elements, the piezoresistive response became unstable at temperatures above 1225 C. In contrast to this, ceramic sensors prepared with 5 microns-thick ITO were stable beyond 1430 C and sensors prepared with 8 microns-thick ITO survived more than 20 hr of operation at 1481 C. Very thick (10 microns) ITo strain gages were extremely stable and responsive at 1528 C. ESCA depth profiles confirmed that an interfacial reaction between the ITO strain gage and alumina substrate was responsible for the high temperature electrical stability observed. Similar improvements in high temperature stability were achieved by doping the active ITO strain elements with aluminum. Several Sic-Sic CMC constant strain beams were instrumented with ITO strain gages and delivered to NASA for testing. Due to the extreme surface roughness of the CMC substrates, new lithography techniques and surface preparation methods were developed. These techniques relied heavily on a combination of Sic and A12O3 cement layers to provide the necessary surface finish for efficient pattern transfer. Micro-contact printing using soft lithography and PDMS stamps was also used to successfully transfer the thin film strain gage patterns to the resist coated CMC substrates. This latter approach has considerable potential for transferring the thin film strain gage patterns to the extremely rough surfaces associated with the CMC's.Gregory, Otto and Fralick, Gustave (Technical Monitor)Glenn Research CenterHIGH TEMPERATURE; STRAIN GAGES; THIN FILMS; ITO (SEMICONDUCTORS); THERMAL STABILITY; SURFACE ROUGHNESS; SURFACE FINISHING; HIGH TEMPERATUR
