Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..
Silicon Nitride is also a widely used insulating thin film and is effective as a barrier against mobile, ion diffusion in particular, sodium and potassium ions found in biological environments. It''s young''s modulus is higher than that of silicon and its intrinsic stress can be controlled by the specifics of the deposition process.

A Technique for Estimation of Residual Stress and Young’s Modulus of Compressively Stressed Thin Films Using Microfabried Beams Abstract: Predictive design of MEMS devices and their performance evaluation require post-fabriion measurement of essential material properties, such as Young’s modulus and residual stress, as these are usually affected by fabriion process conditions.

Young''s modulus is named after Thomas Young, the 18th Century British scientist. However, the concept was developed in 1727 by Leonhard Euler and the first experiments that used the concept of Young''s modulus in its current form were performed by the Italian scientist Giordano Rici in 1782 - predating Young''s work by 25 years [2] .
iv ABSTRACT The microstructure, hardness, fracture toughness, Young’s modulus, strength and Weibull modulus of silicon carbide-titanium diboride (SiC-TiB 2) ceramics were studied. First, SiC-TiB 2 ceramics with 15 vol.% TiB 2 particles were processed using
innovator of multi-filament silicon carbide-type fibers. HI-NICALON TYPE S is a stoichiometric beta-SiC fiber manufactured near-oxygen-free using de-carbonization pyrolysis and electron-beam curing. It has higher modulus, creep resistance and oxidation
CFRP has low density, and high Young''s modulus and strength. CFRP must be processed directly to shape by laying up partially-cured layers of material, and then hot pressing - this is expensive. Carbon fibres are also expensive to produce, and it is only 25 years since the process to …
영률(영어: Young’s modulus, Young modulus)은 고체 재료의 강성을 측정하는 역학적 특성이다. 영률은 단축(uniaxial) 변형 영역에서 선형 탄성 재료의 응력(단위 면적 당 힘)과 변형률 사이의 관계를 정의하는 탄성계수이다. 1차원의 예로 설명하면, 영률을 E라고 할 때, 변형력(stress) = E × 변형도(strain) 로
