oxidation of the SiC/PyC coated carbon fiber is owing to the diffusion of oxygen through the cracks generated by the mismatch of thermal expansion.关键词:......
,because of large CTE(coefficient of thermal expansion)mismatch between amorphous interlayer and alumina substrate.Therefore,only when the joining temperature was appropriate(1200 C),defect-free......
the mismatch of coefficients of thermal expansion between n-SiC and 2014Al matrix. The results are beneficial to fabricating high performance composites for the application in automobile field......
composites,which was the failure between PyC coating and AZ91 D alloy due to the mismatch of thermal expansion and relatively poor bonding, was proposed. Fracture surface of the PyC-Cf/AZ91 D......
strong anisotropy in thermal expansion is favorable in minimizing the coating/substrate mismatch if preferred orientation of HE(Yb0.25Y0.25Lu0.25Er0.252 SiO5 is controlled on either metal or ceramic......
, considering not only the traveling-wave effect and partial coherence effect, but also the seismic non-stationary characteristics of multi-support earthquake motion, was simulated using finite element method......
formation increased significantly from the micrometer to millimeter scale.Thermodynamically,the introduction of Pd could effectively increase the atomic size mismatch and heat of mixing,which......
Miscibility Calculation of GaN1-xPx Ternary Alloys Zhang Rong1,Zheng Youdou1,Chen Dunjun1,Zhang Kaixiao2,Zhu Weihua2,Lin Jianwei2 (1.Department of Physics, Nanjing University, Nanjing 210093, China;2.College of Science, Hohai University, Nanjing 210098, China) Abstract:A theoretical calculation of the miscibility gap with considering the mismatch strain and elastic parameters was performed......
expansion mismatch can then lead to the emergence of dislocations and microcracks. Interfaces and boundaries of different types are found to exist inside the Al2O3/(W, Ti)C rare earth ceramic composite......
of the composite can be obviously decreased by the releasing of the thermal mismatch stress (TMS) in thermal cycling process. The TMS induces the irreversible phase transition of Li+ order-disorder of Euc......
