Coefficient of thermal expansion of AlMgB14

Scripta Materialia, 2002
Abstract The coefficient of thermal expansion (COTE) of AlMgB14 was measured by dilatometry and by high temperature X-ray diffraction using synchroton radiation. The COTE over the temperature range 298 K to 1373 K was determined to be 9×10−6 K−1, which is relatively close to the value of 8.3×10−6 K−1 for pure B.

Thermal Expansion Coefficients of Bismuth

Journal of Applied Physics, 1960
The linear thermal expansion coefficients of the a and c axes of bismuth have been measured from 80°K to 540°K by mechanical means. These same coefficients were determined over a more limited range of temperatures by single crystal and powder x-ray methods. The mechanical and x-ray values did not differ significantly.

Prediction method of thermal expansion coefficient for 2D composite fabric

Mechanics of Advanced Materials and Structures
In this article, an analytical method for predicting the thermal expansion coefficient of 2D composite fabrics is established. First of all, different from the traditional prediction of thermal expansion coefficient by classical laminate theory, this ...

Effect of coefficient of thermal expansion on microleakage

The Journal of the American Dental Association, 1988
This study examines the relationship between thermal coefficient of expansion and microleakage. Six restorative materials with varying coefficients of thermal expansion were thermocycled in basic fuschin dye and compared for relative microleakage. The use of dental restorative materials with low coefficients of thermal expansion such as glass ionomer ...

Tunable coefficient of thermal expansion of Cu-B/diamond composites prepared by gas pressure infiltration

Journal of Alloys and Compounds, 2019
Cu-B matrix composites reinforced with diamond particles (Cu-B/diamond) were prepared by gas pressure infiltration (GPI). The effect of boron addition in the range of 0–1.0 wt% on the thermal expansion behavior of the Cu-B/diamond composites was ...

Measurement of thermal expansion coefficient of human teeth

Australian Dental Journal, 1989
AbstractThe coefficient of thermal expansion of specimens from 60 freshly extracted human teeth were measured over the range 10–80°C using a dilatometer. The coefficient increased rapidly above 50°C, but there was no significant variation with tooth age between 10 and 70 years.

Investigation of micro-yield strength and coefficient of thermal expansion of Al–Cu–Mg–Li–Sc–Ag alloys with various contents of Li

Journal of Materials Research, 2019
In this study, the effects of lithium(Li) content (1.0, 1.5, 2.0, and 2.5 wt%) on the microstructure, micro-yield strength (MYS) and coefficient of thermal expansion (CTE) of Al–Cu–Mg–Li–Sc–Ag alloys were investigated.

The coefficient of thermal expansion of stroma

Experimental Eye Research, 1971
Abstract Rabbit stroma has a negative coefficient of thermal expansion. Upon raising the temperature of a bare stroma, 200 μm thick, from 1–37°C while bathed in isotonic saline and loaded to 53 mmHg swelling pressure the thickness decreases about 14 μm. An increase in thickness of about the same amount can be observed upon cooling a bare stroma. This
