SMA is a good candidate for active control of the smart composite structures. This paper reveals the investigation of coefficient of thermal expansion (CTE) of as-cast and Aluminium 2024/ Cu-Al-Ni shape memory particulate composites. These composites were subjected to shape memory effect by ...
Thermal coefficient of expansion of building materials: Here we provide a Table of Coefficient of Thermal Expansion of Building Materials - what is the linear expansion of glass, metal, wood, masonry or plastic in response to temperature changes. We include a discussion of the definition of therm...

Fig. 1. Schematic of the laser powder bed fusion process. Thermal expansion can be problematic in many areas of engineering, not least during the PBF process itself where higher silicon content in aluminium alloy powders can help lower thermal expansion and prevent crack formation [5] during the...
The incorporation of these metal ions has resulted in reductions in the CTE's of the control polyimides of 12 percent to over 100 percent depending on the choice of additive and its concentration. 展开 关键词: materials science aluminium metallurgical effects dysprosium erbium europium holmium imides...

The coefficient of thermal expansion was accurately determined over a wide range of temperatures from 350 to 1080 K for mechanically alloyed quasicrystals. The relaxation of phason-type quasilattice defects contributes into the value of thermal expansion coefficient under heating, while its value for an...
With respect to temperature, the magnitude of the CTE increases with rising temperature. Thermal expansion of pure metals has been well characterized up to their melting points, but data for engineering alloys at very high temperatures may be limited. In general, CTE values for metals fall between...
