    The amplitude-dependent internal friction in carbon fiber reinforced plastic (CFRP) laminates subjected to fatigue cycling has been measured and analyzed to convert into the plastic strain of the order of 10-8 as a function of effective stress. The microplastic flow indeed occurs in the stress range three orders of magnitude lower than the failure stress, and the stress-strain curves tend to shift to a lower stress as the number of cycles increases, thus indicating a decrease in the CFRP strength. The microflow stress at the plastic strain of 1×10-8 keeps a constant value of about 0.4 MPa in the range less than 103 cycles but then decreases gradually, whereas the Young’s modulus evaluated from the resonant frequency is almost constant up to 104 cycles where only transverse cracks are found. Thus we can successfully detect the onset of fatigue deterioration by means of the amplitude-dependent internal friction.

  • Effects of Grain Size on Deformation Behavior of Heusler-type Fe2VAl Alloys Reviewed International journal

    The deformation behavior of fine-grained Heusler-type Fe2VAl alloys (average grain diameter d = 14, 2.0, 1.4 and 0.4 μm) made by pulse current sintering (PCS) has been investigated in comparison with the arc-melted alloys with d = 130 μm. The yield stress of the Fe2VAl alloys at 300 K increases as the grain size decreases, following the Hall-Petch relationship except for d = 0.4 μm. An anomalous increase in the yield stress with increasing temperature can be observed for d = 14 and 130 μm, whereas the yield stress peak disappears for d = 2.0 μm. The yield stress decreases at a lower temperature for finer grains, which occurs in parallel with a steep rise in the strain rate sensitivity exponent m. The m value for d =2.0 μm reaches the maximum of 0.32 at 1123 K, and the temperature is almost 200 K lower than that for d =130 μm. The decrease in the yield stress can be explained by a lower temperature superplasticity for finer grained alloys.

    We report the thermoelectric properties of the off stoichiometric Fe2-yV1+x+yAl1-x alloys in the temperature range from 300 to 750 K. Fe2-yV1+x+yAl1-x alloys with V rich (1+x+y>1-x, i.e., y>-2x) and Al rich (y<-2x) composition show the negative and positive sign of Seebeck coefficient, respectively, and the peak temperature of Seebeck coefficient shifts to the higher temperature side with increasing V and Al composition. Electrical resistivity of Fe2-yV1+x+yAl1-x alloys shows the metallic temperature dependence. Due to the combination of the Fe/V and V/Al off stoichiometric effects, Fe1.97V1.12Al0.91 and Fe2.03V0.89Al1.08 alloys show the highest power factors of 4.03×10-3 W/mK2 for n type and 2.52×10-3 W/mK2 for p type at 500 K, respectively.

    The thermoelectric power of Fe2VAl can be expected to be well enhanced by doping or off-stoichiometry, because the density of states rises sharply in both sides of the pseudogap. We will investigate the temperature dependence of the Seebeck coefficient and the electrical resistivity in the Fe2VAl-based alloys, in addition to the measurement of the thermal conductivity at room temperature, to clarify the doping effect on the thermal and transport properties.

    自動車や自動二輪車など移動体の内燃機関からの排熱を有効利用する方法として熱電変換が検討されている。レアメタルフリーでしかも高強度なFe2VAl系熱電素子材料については,これまでアーク溶解法で作製されているが,低コストで素子を大量生産することを目指して鋳造法による作製可能性を検証する。とくにFe2VAl系鋳造材の組成制御方法を確立し,V/Al組成比を化学量論比からわずかにずらすことにより,アーク溶解材のゼーベック係数の9割以上を目標として材料開発を行う。さらに,鋳造による急冷効果を利用すれば凝固組織の微細化により熱伝導率を低減できるので,300℃での熱電性能指数ZT=0.25の達成を目指す。

    高強度なホイスラー化合物をベースにして,熱伝導率を広範囲に制御できる熱電材料開発を行うことを目的とした。p型性能向上のため,非化学量論組成Fe#D2#DRVAlをベースとしてTiで置換した結果,ゼーベック係数の最大値は340Kにおいて106μV/Kになった。このp型とn型材料と組み合わせると,ゼーベック係数の絶対値の和は266μV/Kとなった。n型についてはSi置換合金が優れた熱電特性を有しており,Vの一部を同族のTaで置換して熱伝導率を約7W/mKまで低減させることに成功した。重元素置換だけでは熱伝導率は目標の5W/mKには届かなかったが,組織微細化を組み合わせることで目標を達成できる見通しが立った。
