Linear Thermal Expansion Coefficients of Higher Manganese Silicide Compounds

Fiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)

The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...

Micromechanical Analysis of Thermal Expansion Coefficients

Thermal expansion coefficients play an important role in the design and analysis of composite structures. A detailed analysis of thermo-mechanical distortion can be performed on microscopic level of a structure. However, for a design and analysis of large structures, the knowledge of effective material properties is essential. Thus, either a theoretical prediction or a numerical estimation of t...

Development of Solution-Processable, Optically Transparent Polyimides with Ultra-Low Linear Coefficients of Thermal Expansion

This paper reviews the development of new high-temperature polymeric materials applicable to plastic substrates in image display devices with a focus on our previous results. Novel solution-processable colorless polyimides (PIs) with ultra-low linear coefficients of thermal expansion (CTE) are proposed in this paper. First, the principles of the coloration of PI films are briefly discussed, inc...

Adjustable zero thermal expansion in antiperovskite manganese nitride.

It is general knowledge that materials expand with increasing temperature and contract with decreasing temperature. Only few materials seem to neither expand nor contract over a certain temperature range and thus feature near zero thermal expansion (ZTE) behavior. These materials are the focus of recent scientifi c work [ 1–5 ] and have potential technical applications in both structural materi...
