Relationship between metallic multilayers hardness and monolayer thickness has been investigated and explained for electroplated Ag/Cu and Cu/Ni multilayers using a modified Thomas-Fermi-Dirac electron theory. Experiments reveal that the peak hardness of Ag/Cu multilayers occurs at the monolayer thickness of about 25 nm, while the peak hardness of Cu/Ni multilayers occurs at about 50 nm. Critical monolayer thickness corresponding to the peak hardness is approximated by the grain size limit of stable dislocations in Ag crystals for the Ag/Cu multilayers and in Cu crystals for Cu/Ni multilayers. Grains size limits are calculated based on a modified Thomas-Fermi-Dirac electron theory. Developed relationship between the critical monolayer thickness and the grains size limit helps understand nanoscale metallic multilayers softening.  相似文献

针对Ni80Fe20/Mo纳米多层膜在实际应用中经常面临的热稳定性问题,研究了多层膜在343-683K温度范围内的互扩散行为,测定了其有效互扩散系数Dλ。小的激活焓来源于多层膜中存在的共格应变。当温度低于483K时,NiFe/Mo多层膜具有较强的抵制NiFe和Mo亚层间互扩散能力,这对NiFe/Mo多层膜今后的实际应用有重要意义。  相似文献

Reflection measurements in the 25-35 nm region were made for Mg/SiC and Mg/Y2O3 multilayers kept in a low-humidity atmosphere for 4 or 5 years. Aged Mg/SiC multilayers keep their reflectances, and the reflectance value at 31.2 nm is 0.44 at 10 degrees of the normal angle of incidence. Aged Mg/Y2O3 multilayers change reflectance as top layer materials, and the best value at 30.1 nm is 0.40 at 10 degrees. Reflection measurements are also made for Mg-based multilayers that are annealed from room temperature to 400 degrees C at 50 degrees C intervals. Both multilayers keep their reflectance at annealing temperatures of 200 degrees C. These results suggest that both Mg-based multilayers can be applied to practical optics.  相似文献

Using reactive radio frequency magnetron sputtering, TiN/ZrN multilayers were deposited on Si (111) substrates at 550 °C. The multilayers were annealed at different temperatures ranging from 500 to 1100 °C in air. The variation of the annealed multilayers has been investigated by X-ray diffraction and transmission electron microscopy. A layer-by-layer oxidation behavior is found in the multilayers annealed at temperatures below 900 °C. The oxidation mechanism of multilayers is discussed in the paper.  相似文献

The effect of thermal treatments on mechanical properties was systematically investigated in Ni/Mo multilayers with a constant modulation period(160 nm)prepared by magnetron sputtering deposition.A supermodulus effect was found in the annealed multilayers as compared to the as-deposited state.A large tensile stress development was observed in the multilayers.The evolution of grain-boundary(GB)wetting was observed at the interfaces of the multilayers,which results in an enhanced modulus based on the mechanism of GB-wetting-induced interfacial stress/strain.The GB wetting phenomenon was further supported by a thermodynamic calculation.The results not only bring clear evidence of the important role of interfacial structures in governing the elastic behavior of metallic multilayers,but also allow designing the multilayers with special properties through atomic diffusion and wetting at the interfaces based on the thermodynamic calculation.  相似文献

在室温下,分别利用常规磁控溅射和反应磁控溅射技术交替沉积Si薄膜和Si1-xNx薄膜在单晶硅基体上制备了Si/Si1-xNx纳米多层膜。接下来,在高温下对Si/Si1-xNx多层膜进行退火诱发各层中形成硅纳米晶。研究了Si1-xNx层厚度和N2流量沉积对Si/Si1-xNx多层膜中Si量子点形成的影响。TEM检测结果表明,N2流量为2.5mL/min时沉积的多层膜退火后形成了尺寸为20~30nm的等轴Si3N4纳米晶;N2流量为5.0mL/min时沉积的多层膜退火后在Si层和Si1-xNx多层中均形成了硅纳米晶,而在7.5mL/min N2流量下沉积的Si/Si1-xNx多层膜退火后仅在Si层中形成了硅纳米晶。  相似文献

采用非均匀体系非线性动力学离散模型计算AB二元系纳米多层薄膜的非线性互扩散,研究了A、B原子间作用力之差VBB-VAA和有序能V对纳米多层薄膜浓度分布和界面结构的影响.对于V≤0的纳米多层薄膜,随着VSS-VAA由0减小到-0.05eV,扩散过程中多层薄膜浓度偏离对称分布,界面由宽化向平直转变,有序能V由0减小到-0.025eV,导致多层薄膜的扩散速度加快.当V>0时,扩散过程中多层薄膜出现相分离趋势导致的上坡扩散,初始宽化互混的界面变得平直,且随着VBB-VAA由0减小到-0.05V,多层薄膜扩散过程中形成的浓度起伏长大成为新的亚层.AB二元系纳米多层薄膜扩散过程中的浓度分布和界面结构演变与扩散非对称性系数m'、有序能V和初始时刻的浓度梯度有关.  相似文献

The formation of metastable cubic AlN (c-AlN) and its effect on the mechanical properties of AlN/TiN nanomultilayers were studied. A series of AlN/TiN multilayers with different modulation periods were prepared by reactive magnetron sputtering. The microstructure and mechanical properties of multilayers were characterized with low-angle X-ray diffraction, transmission electron microscopy and a microhardness tester. The results show that AlN exists as a metastable cubic phase in multilayers at small modulation periods due to the “template effect” of TiN layer and forms superlattice with TiN through coherent epitaxial growth. Correspondingly, multilayers show the superhardness effect with the enhancement of hardness at small modulation periods. With the increase of modulation periods, AlN layer grows as c-AlN firstly and then its stable hexagonal structure (h-AlN) appears and grows on the already formed c-AlN. Correspondingly, the hardnesses of the multilayers decrease. The change of properties with the formation of c-AlN and the alternative strain field resulting from coherent growth of c-AlN and TiN are likely reasons for the superhardness effect of AlN/TiN multilayers.  相似文献
