Anisotropy of Linear Thermal Expansion Coefficient of a Disk Injection Molded from Reinforced PA 66

Thermal Processing of Injection-Molded Silicon Carbide

Silicon carbide is the most important and versatile non-oxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding—removal of organic additives—is the rate-limiting step in P...

Linear Coefficient of Thermal Expansion of Porous Anodic Alumina Thin Films from Atomic Force Microscopy

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...

Thermal expansion coefficient of hydrogenated amorphous carbon

The coefficient of thermal expansion ~CTE! of hydrogenated amorphous carbon (a-C:H) was investigated as a function of the concentration of sp hybridization. The CTE, determined using the thermally induced bending technique, depends on the concentration of sp bonded carbon, increasing to the value of graphite as the sp concentration approaches 100%. By using a combination of the thermally induce...

On the Determination of Thermal Expansion Coefficient of Thermal Oxide

The accurate value of thermal expansion coefficient ( ) of thin film is an important thermal property in the design of microelectronic devices and microsystem. This research presents a microbridge buckling deformation caused by the residual stresses to determine the of thermal oxide (SiO2) film. The extraction of is supported through experimental means and finite element analysis (FEM) of the b...
