摘要： The present invention provides a magnetostrictive member with high performance, high reliability and high versatility. The magnetostrictive member is used in the vibration power generation as a power source for extracting electric energy from various vibrations.The member made of the single crystal is manufactured cheaper than the conventional manufacturing method. The magnetostrictive member is formed by cutting a single crystal of Fe—Ga alloy by using electric discharge machining in a state that orientation of the crystal of the Fe—Ga alloy is aligned in a direction in which magnetostriction of the magnetostrictive member is required.

摘要： This hot work tool steel has a composition containing C: 0.45 to 0.57 mass %, Si: 0.05 to 0.30 mass %, Mn: 0.45 to 1.00 mass %, Cr: 4.5 to 5.2 mass %, Ni: 0.5 mass % or less, Mo+(½) W: 1.0 to 2.0 mass %, V: 0.30 to 0.80 mass %, and N: 0.008 to 0.025 mass %, the remainder being Fe and unavoidable impurities, and the area ratio of carbide having an equivalent circle diameter of 1 μm or less being 20% or higher. It is thereby possible to improve thermal conductivity to thereby shorten cycle time, and improving hardness after heat treatment to improve abrasion resistance while sufficient hardenability is maintained. Consequently, it is possible to obtain a hot work tool steel having excellent toughness with high hardness, excellent corrosion resistance, and minimal degradation of machinability.
