The following thermal expansion chart compares the "Coefficient of linear thermal expansion" shown as a factor m/m.k in the table. All materials expand with changes in Temperature. Thermoplastics ...

Thermal expansion is a common phenomenon in nature. It often leads to structural disorder or loss of precision, ultimately compromising material performance. The researchers led by Prof. Liu ...

The discovery of this field-induced sign change could offer a new way of controlling a material’s thermal expansion – a prospect that would have many industrial applications as well as interest for ...

Thermal design has become a first-order constraint in GaN system performance. As GaN pushes deeper into high-power, ...

This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1,400 Kelvin (-269 to 1126 °C, -452 to ...

Now a team at Los Alamos National Laboratory has developed a way to directly measure such materials’ thermal expansion coefficient, the rate at which the material expands as it heats. That insight can ...

Using high-throughput calculations and symbolic regression, they helped discover 2D materials with extremely low or high thermal expansion coefficients, including ZTE and 2D anti-Invar monolayers.

Unlike most materials, cordierite displays an unusual combination of thermal expansions: low positive expansion along two perpendicular axes and negative expansion along the third. This unique ...

but the problem has a wider application and is also identical with the problem of deducing the coefficient of thermal expansion for a similar material.

The work could make it possible to develop alloys in which positive and negative expansion cancel each other out, producing a composite material with a net-zero thermal expansion – a highly desirable ...
