非晶态合金作为特殊功能材料的研究是近年来国外金属材料科学研究的新方向。此文从特殊功能材料的八个方面列举了非晶态合金的最新研究成果：1．低膨胀材料。其中以Fe84B16为典型,α(-196°-200℃)≤0．50×10-6／℃。2．恒弹性材料。某些非晶态合金不仅具有因瓦特性、也同时兼有艾林瓦特性,如Fe-B系,Fe-Si-B系、Fe-Cr-C系及Pd-Si系非晶态合金。它们在作延迟线使用时,更具有传输衰减小等突出优点。3．耐蚀材料。作为耐蚀非晶态合金使用的有：Fe70P13C7Cr10、Ni70P15Cr15、Cu50Ti50及Pd77．5Cu6Si16.5等典型成分,其耐蚀性一般超过常用不锈钢几个数量级。4．吸振材料。非晶态吸振合金特点是能在不同振动频率下及微小振幅下保持高衰减能特性。5．高磁致伸缩材料。具有极高λs值(λs-1700×10-6)6．转换(传感器)材料。已在机械形变及温度两方面作传感器材料应用。7．超高强度材料。其中Fe-Cr-Mo-B非晶态合金σb≥400kgf／mm2,Fe-W-C非晶态合金Hv=1050kgf／mm。8．精密电阻材料。如Ta-Co非晶态合金。最后,此文对非晶态合金在工艺制备方面的最近发展动态作了简要介绍。
Research on amorphous alloy as a special functional material is a new direction of scientific research on metal materials in foreign countries in recent years. This article lists the latest research results of amorphous alloys from eight aspects of special functional materials: 1. Low expansion material. Among them, Fe84B16 is typical, α (-196 ° -200 ℃) ≤0.50 × 10-6 / ℃. 2. Constant elastic material. Some amorphous alloys not only have the characteristics of Invar, but also both have Alvarez characteristics, such as Fe-B system, Fe-Si-B system, Fe-Cr-C system and Pd-Si system amorphous alloy. When used as a delay line, they have the advantages of small transmission attenuation and other advantages. 3. Corrosion-resistant material. As a corrosion resistant amorphous alloy used are: Fe70P13C7Cr10, Ni70P15Cr15, Cu50Ti50 and Pd77.5Cu6Si16.5 and other typical components, the corrosion resistance of stainless steel is generally more than several orders of magnitude. 4. Vibration absorbing material. Non-crystalline vibration-absorbing alloy is characterized by high attenuation energy characteristics under different vibration frequencies and small amplitude. 5. High magnetostrictive material. Has an extremely high λs value (λs-1700 × 10-6) 6. Convert (sensor) material. Has been in mechanical deformation and temperature sensor materials for both applications. 7. Ultra-high strength material. Fe-Cr-Mo-B amorphous alloy σb ≥ 400kgf / mm2, Fe-W-C amorphous alloy Hv = 1050kgf / mm. 8. Precision resistance material. Such as Ta-Co amorphous alloy. Finally, this article gives a brief introduction of recent developments of amorphous alloys in process preparation.
