Abstract

A conventional push-rod dilatometer is modified in order to accurately correlate the measured density to the predicted sample temperature of alloys in the phase-change regime. This new configuration makes use of a standard furnace assembly; however, the specimen is now symmetrically encased in a well-instrumented, graphite cylindrical shell. The combination of system geometry and high-conductivity sample holder material promotes the development of a simplified heat transfer model. The solution of this model properly correlates the measured density to that of the actual sample temperature based on using remote, sample-holder temperature measurements. Preliminary results using aluminum A356 provide insight into the proposed configuration.

Inverse Process Analysis for the Acquisition of Thermophysical Data

Technical Report Frankel, Jay ; Sabau, Adrian

One of the main barriers in the analysis and design of materials processing and industrial applications is the lack of accurate experimental data on the thermophysical properties of materials. To date, the measurement of most of these high-temperature thermophysical properties has often been plagued by temperature lags that are inherent in measurement techniques. These lags can be accounted for with the appropriate mathematical models, reflecting the experimental apparatus and sample region, in order to deduce the desired measurement as a function of true sample temperature. Differential scanning calorimeter (DSC) measurements are routinely used to determine enthalpies of phase change, phasemore »« less

AN AUTOGRAPHIC STRAIN-GAGE DILATOMETER FOR PLUTONIUM AND ITS ALLOYS

Technical Report Elliott, R O ; Miner, W N

A vacuum dilatometer for use in determiming the expansion characteristics of plutonium and its alloys is described. The dilatometer consists of a vertical silica tube containing the specimen and a silica push tube which transmits specimen expansion to a cantilever beam. Strain gages cemented to the beam convert linear displacement of the specimen into an electrical signal that is fed to a Leeds and Northrup X-Y recorder. Specimen temperature, as determined by a thermocouple, is also fed to the recorder. Heating of the specimen is obtained by means of at split-tube furnace. The principal advantages of this dilatometer over themore »« less
Laser interferometric dilatometer for low-expansion materials

Conference Drotning, W D

The development of a high-precision dilatometer based on interferometry presents a number of challenges. This paper describes a laser interferometric dilatometer developed for high-precision thermal expansion measurements in the materials laboratory. The Sandia dilatometer uses dual-beam laser interferometry with a computer-controlled optical alignment feature to achieve high-precision length change measurements. This device has been modified to expand its measurement capabilities in a number of areas. A new thermal chamber has been incorporated which provides a range of measurement from 90 to 500 K while minimizing thermal effects on the optical portion of the instrument. A new specimen holder has beenmore »« less

Thermal expansion of epoxy-fiberglass composite specimens

Conference McElroy, D L ; Weaver, F J ; Bridgman, C - Int. J. Thermophys.; (United States)

The thermal expansion behavior of three epoxy-fiberglass composite specimens was measured from 20 to 120/degree/C (70 to 250/degree/F) using a fused quartz push-rod dilatometer. Billets produced by vacuum-impregnating layers of two types of fiberglass cloth with an epoxy were core-drilled to produce cylindrical specimens. These were used to study expansion perpendicular and parallel to the fiberglass layers. This type of composite is used to separate the copper conductors that form a helical coil in the Advanced Toroidal Facility, a plasma physics experiment operated by the Fusion Energy Division at Oak Ridge National Laboratory. The coil is operated in a pulsedmore »« less
