块体非晶合金制备技术展望

非晶合金的初始状态多为粉末或薄条带，这就大大限制了非晶合金的许多优异性能的发挥以及在工业中的应用。所以开发研究块体非晶合金有其重大的理论和应用价值。本文从四个研究方面归纳了当前研究状况，即粉末冶金技术、固态反应、从液相中直接制取、非晶条带直接复合等。本文简单介绍了前三种方向，重点论述非晶条带直接复合即非晶块的爆炸焊接制备技术，复合后的块体能保证非晶态，用它来制备非晶合金块的前景广阔。

Prospect of the Techniques about Manufacturing Bulk Amorphous Alloys

In order to make full use of the potentially useful properties of amorphous alloys and extend the industrial applications,it is important to prepare amorphous alloys in a bulky form The current research is sorted in four aspects,namely,powder metallurgy technique,solid state reaction,bulk amorphous alloys making from melt directly and amorphous alloys ribbons with explosive welding The former three aspects are introduced in brief and the last is discussed in detail For the last,the bulk amorphous can be produced by explosive welding with amorphous ribbons directly What's more, it could dispose of the oxide films and the amorphous state of the amorphous ribbons can be maintained in bulk samples after explosive welding So the explosive welding for producing the bulk amorphous alloys has bright future
