非晶态金属(又称金属玻璃或无定形金属),自六十年代问世以来,人们对这类新型材料产生了极大兴趣,并且从理论和实用方面进行了大量的研究。PdSi系非晶态合金发现较早,在1965年就有报道。后来,H.S.Chen等又发现,在PdSi合金中加入少量Au、Ag、Cu等元素,能促进非晶态金属的形成,并提高它们的稳定性,某些三元合金,如Pd Ag_6 Si_(16.5)等,在冷却速度低至10~2℃/秒时也能获得厚度大于1mm的非晶态合金。近几年来,我们用液态金属高速冷却技术研制了数种Pd Si以及Pd Si基中分别 Amorphous metal (also known as metal glass or amorphous metal), since the advent of the 1960s, people have great interest in this new type of material, and from the theoretical and practical aspects of a large number of studies. PdSi amorphous alloy found earlier, reported in 1965. Later, HSChen et al. Found that adding a small amount of Au, Ag, Cu and other elements into the PdSi alloy can promote the formation of amorphous metals and improve their stability. Some ternary alloys, such as Pd Ag 6 Si 16.5 ) And the like, amorphous alloys having a thickness of more than 1 mm can also be obtained at cooling rates as low as 10 to 2 ° C / sec. In recent years, we have used liquid metal high-speed cooling technology developed several kinds of Pd Si and Pd Si base respectively
