Along with testing for thermal expansion, testing should also be conducted for acid resistance, resistance to alkalis and testing for vitrification, at a minimum.
In the case of the composite based on polymer blend, thermal expansion under heating can be rather complicated.
For some of Amite's specialty castings, zircon sand was used to give the metal a good surface finish and because its low thermal expansion aided shakeout.
Thus, if a ceramic having high a thermal conductivity and a low coefficient of thermal expansion is (with in proper percentage) combined with a polymer having a low dielectric constant and a low manufacturing cost, a satisfactory material can be developed for electronic packaging (4).
When approximately 28% or more nickel is present in iron, the crystal structure is austenite, but, because the Curie temperatures (where feromagnetics lose their magnetism) of these alloys are above room temperature, they are ferromagnetic and, as a result, exhibit abnormal thermal expansion.
It shows the combinations of physical relaxation and thermal expansion effects over a range of compressions and thermal exposure that bring the sample back to its original condition with its initial dimensions at no load.
At that time, researchers found a new reason to pay attention to the thermal expansion of materials: Heat generated by electronic circuit boards in computers was causing them to self-destruct.
Another familiar case is a bimetalic strip consisting of a thin strip of two isotropic homogenous materials with different coefficients of thermal expansion cemented together.
This high temperature bulk powder cooling system has a tube exchanger that minimizes thermal stresses and accommodates thermal expansion.
Flax fibers minimize thermal expansion and contraction.
The low hot strength can result in an increased frequency of casting defects, such as veining and core breakage, and hot distortion from thermal expansion and resin breakdown under high temperatures.
