Effect of Substrate Bias on Microstructure and Properties of Tetrahedral Amorphous Carbon Films

Jiaqi ZHU , Jiecai HAN , Songhe MENG , Qiang LI , Manlin TAN

材料科学技术(英文)

The microstructure and properties of tetrahedral amorphous carbon (ta-C) films deposited by the filtered cathodic vacuum arc technology has been investigated by visible Raman spectroscopy, AFM and Nano-indentor. The Raman spectra have been fitted with a single skewed Lorentzian lineshape described b...

Prediction Models on Distribution of Inherent Strains in T Type Welding Structure

Peng HE , Jicai FENG , Jiecai HAN , Yiyu QIAN

材料科学技术(英文)

A fundamental theory for the analysis of residual welding stresses and deformation based on the inherent strain distribution along the welded joint is introduced. The method of predicting maximum hardness Hv(y, z) and maximum inherent strain gmax is given. The model T.E.P-Tav-hardness calculation is...
