| 中文摘要: |
| 非晶合金又称“金属玻璃”,是由于超快速冷却凝固导致无法有序排列结晶，从而得到的一种长程无序结构。这种非晶合金与存在晶界和位错的普通合金相比，具有更加优异的力学及物化性能。由于粉末状或条状非晶合金在尺寸和性能等方面的限制，因而大尺寸、优异力学性能及软磁性能卓越的块体非晶合金的制备受到了大量关注与探究。放电等离子烧结技术以温度低、效率高、时间短及冷却速率快等优点,被认为是一种具有广阔发展前景的制备方法。对Fe基、Zr基、Al基及Ti基本身的特点，以及通过放电等离子烧结技术制备不同体系块体非晶合金的物理及化学性能的研究进行了较为全面的综述。概述了放电等离子烧结技术的原理及在制备块体非晶合金方面的优势;分析了放电等离子烧结技术和制备的块体非晶合金材料存在的问题，以及采用该技术制备块体非晶合金的发展前景。重点介绍了在采用该制备不同体系的块体非晶合金时，如何通过改变放电等离子烧结参数，或通过再加工、本身粉末添加元素等方法获得大尺寸、优异性能的块体非晶合金。 |
| 英文摘要: |
| Amorphous alloy is also called "metallic glass". It is a kind of long range disordered structure that can not be orderly arranged and crystallized due to ultra fast cooling and solidification. Compared with ordinary alloys with grain boundaries and dislocations, this amorphous alloy has more excellent mechanical and physicochemical properties. Due to the size and performance limitations of powder or strip amorphous alloys, the preparation of bulk amorphous alloys with large size, excellent mechanical properties and excellent soft magnetic properties has received a lot of attention and research. Spark plasma sintering (sps) is considered to be a promising preparation method for its low temperature, high efficiency, short time and fast cooling rate. The characteristics of Fe based, Zr based, Al based and Ti based alloys, as well as the physical and chemical properties of different bulk amorphous alloys prepared by spark plasma sintering were reviewed. The technical principle of spark plasma sintering and its advantages in preparing bulk amorphous alloys are summarized in detail; The problems of spark plasma sintering technology and bulk amorphous alloy materials were analyzed, as well as the development prospect of bulk amorphous alloy prepared by spark plasma sintering technology. This paper focuses on how to obtain bulk amorphous alloys with large size and excellent performance by changing the parameters of spark plasma sintering, or by reprocessing or adding elements to the powder itself when using spark plasma sintering technology to prepare different systems of bulk amorphous alloys. |
