Relationship between texture and residual macro-strain in CVD diamond films based on phenomenological analysisWeimin Mao1,2), Hongxi Zhu1), Leng Chen1), and Huiping Feng1) 1) School of Materials... 100083, China摘 要:The relationship between texture and elastic properties of chemical vapor deposition (CVD) diamond films was analyzed based......
solidification setup was used to prepare high purity aluminum ingots of 100mm in diameter. The morphology of the growth interface was detected by SEM and AFM, and the grain lattice orientation was detected by XRD. The results indicate that the grains suffer competitive growth under any conditions in experiments. The lattice orientation of the preferred grains is determined by the flow field above......

such as local composition, morphology, grain boundary characteristics and interphase orientation relationship of a forged Zr-2.5Nb alloy before and after β-air-cooling. Results show that the as-forged...) The crystallographic orientation examination confirms that the Burgers relationship is strictly obeyed during the β→α cooling. 3) Compared with the as-forged specimen, the hardness of the β-air-cooled......
