A Radiographic Method of Dilatometry

Review of Scientific Instruments, 1951
A method of dilatometry using x-ray illumination has been developed and applied to measurements of compressibility. Metal samples, 10 in. long and 316 in. in diameter, are subjected to pressures up to 10,000 atmospheres. Observations of the length of the compressed sample are made by causing x-rays to cast a shadow on a photographic plate.

High temperature dilatometry of Ti-6242

Scripta Metallurgica, 1987
Abstract Both normal heat-treatments and hot compression of Ti-6242 produce a rich variety of non-equilibrium microstructures. It was attempted to characterize subsequent phase transformations by monitoring dilatation during linear heating. The results seem anomalous when compared to simple transformation and solute effects but may be related to ...

Dilatometry of Ni3Al powder disordered by ball-milling

Intermetallics, 1995
Abstract The microstructure and reordering behaviour of Ni3AI-base alloy has been studied following completion of a broader research on ordering kinetics of some intermetallic compounds. A disordered structure has been obtained in powder samples with high energy ball-milling.

Electro-dilatometry of simple liquids

Chemical Physics Letters, 1985
Abstract The effect of a dc electric field ((1–4)×106 V/m) on the changes inthe volume of liquids at 298 K has been investigated for nine pure liquids and one binary liquid mixture. The change in the volume was found to be dependent on E2. Both negative as well as positive volume changes were found.

Differential Dilatometry A Powerful Tool

THERMAL EXPANSION OF SOLIDS — 1973: International Symposium, 1974
Differential dilatometry is a valuable technique for measuring both differential and absolute expansion of materials. The particular advantages of this technique are discussed and a calibration scheme is presented. Its usefulness and versatility are illustrated by establishment of new reference materials and by citing typical applications of the method.

Industrielle Anwendungen Moderner Dilatometrie

1979
Die Anwendung thermoanalytischer Verfahren im industriellen Bereich dient vorwiegend der Materialprufung und Werkstoffentwicklung. Die Dilatometrie hat dabei einen beachtlichen Stellenwert, da das mit Dilatometern leicht bestimmbare Ausdehnungsverhalten von Festkorpern bei Temperaturanderung deren Einsatzmoglichkeiten wesentlich beeinflust. In modernen

Absolute dilatometry using a polarization interferometer

Journal of Physics E: Scientific Instruments, 1975
An instrument for measuring the absolute thermal expansion of solids up to 1000 degrees C is described. A sensitivity of 10-8 degrees C-1 was achieved by means of a frequency stabilizer laser and a polarization interferometer. Details of the laser stabilization technique interferometer, automatic polarimeter, sample chamber and preliminary results on ...

Apparatus and method for volumetric dilatometry [PDF]

, 2016
Disclosed is a novel apparatus and method for volumetric dilatometry. A volumetric dilatometer includes an optical displacement sensor and a means for using a gap measurement obtained from the displacement sensor application in an application which requires the measurement of absolute distance and/or displacement.
