  • Dependence of Vickers Hardness on Layer Thickness in Electrodeposited Ni-Co-Cu/Cu Multilayered Films

    Hagiwara Hiroyuki, Kawakami Naofumi, Kaneko Yoshihisa, Uchida Makoto

    公益社団法人 日本金属学会 MATERIALS TRANSACTIONS  60 ( 12 ) 2569 - 2575 2019.12  [Refereed]

     View Summary

    <p>The layer thickness dependence of Vickers hardness was investigated in Ni–Co–Cu/Cu multilayered films having layer thicknesses <i>h</i> ranging from 10 nm to 300 nm. The Ni–Co–Cu/Cu multilayered films were fabricated by electrodeposition. In the layer thickness range of <i>h</i> ≥ 75 nm, the hardness increased with decreasing layer thickness. Conversely, the hardness decreased with decreasing layer thickness at <i>h</i> ≤ 75 nm. At <i>h</i> = 10 nm, the hardness decreased to 97 HV, although the local maximum at <i>h</i> = 75 nm was 210 HV. In the X-ray diffraction (XRD) profiles around the fcc (111) peak, the 10 nm multilayered film revealed a single peak, while two peaks corresponding to the Ni–Co–Cu and Cu layers were detected in the other multilayered films. The low hardness of the 10 nm film can be understood from the absence of interface strengthening, which was deduced from the single XRD peak. For 20 nm ≤ <i>h</i> ≤ 75 nm, the two (111) peaks approached each other. The decreased hardness in this region could be related to sparse misfit dislocations, which can be estimated from the XRD peak angles.</p>

  • Effects of Layer Thickness and Annealing on Vickers Hardness and Wear Resistance in Ni-P / Zn-Ni Multilayered Films

     View Summary

    <p>We fabricated Ni-P / Zn-Ni multilayered structures on a steel substrate using alternate electroplating with two electrolyte baths. We prepared two series of the multilayered structures to elucidate the effects of component layer thickness and annealing on hardness and wear resistance. In one series, the Ni-P and Zn-Ni layers had equal thicknesses of 200 nm, 500 nm, and 1000 nm, whereas the other series had constant 500 nm Ni-P layer thickness. Then, the electroplated films were annealed at 573 K for 2 hr. For all multilayered structures, the annealing increased the hardness and wear resistance because of Ni-P layer hardening. Among the multilayers having equal component thicknesses, the 500-nm layer thickness exhibited the highest hardness and wear resistance. In the annealed multilayers having constant 500 nm Ni-P thickness, the hardness and wear resistance increased concomitantly with decreasing Zn-Ni layer thickness. Our key finding is that the annealed multilayers consisting of 500-nm Ni-P and 100-nm Zn-Ni layers exhibited three times higher wear resistance than an annealed Ni-P film.</p>

  • Wide-Area Observation of Dislocation Structures around Fatigue Crack using ECCI Method

     View Summary

    Dislocation structures formed near fatigue cracks in copper single crystals and ferritic stainless steels were observed with electron channelling contrast imaging (ECCI) method. The ECCI method is based on the electron channelling phenomenon that intensity of backscattered electrons depends on the angle between incident electron beam and lattice plane. We can observe dislocations lying under surface in a scanning electron microscope (SEM). In the present research, it was confirmed that the dislocation structures such as the persistent slip band (PSB) and the labyrinth structure -- which are generated due to fatigue loading -- were imaged with the ECCI method over a wide area including the crack tip vicinity, at which the TEM observation had been difficult. At the fatigue experiments on the copper single crystals, the dislocation structures formed around fatigue cracks were sensitive to loading axes. At the [001] loading axes, the ladder-like PSB structure and the labyrinth structure were observed around the fatigue crack. The formation of these dislocation structures depended on the angle from crack plane. The distribution of the dislocation structures could be explained by the stress distribution calculated from the linear fracture mechanics. In the crack growth experiments on Fe-30%Cr single crystals, the dislocation structures depended on the mode of fatigue cracks. The cell structure surrounded the fatigue crack having Mode-III component which appeared at <112> and <221> loading axes. On the other hand, no significant dislocation structures were found near the Mode-II fatigue crack propagating at the specimen with <110> loading axis. Only a band-like dislocation structure parallel to the crack plane was emitted from the crack tip. In the polycrystalline Fe-20%Cr alloy, the relationship between crack growth rate and the surrounding dislocation structure was investigated. At a single-slip-oriented grain, the dislocation structure mostly observed in the vicinity of the crack was the vein and the crack growth rate was relatively fast. On the other hand, the cell structure was well developed near the crack in double-slip oriented grains. The fatigue crack with the cell structure propagated at slow crack growth rate.
