TED-Ed(视频版) Metallic glasses look shiny and opaque, like metals, and also like metals, they conduct heat and electricity. 金属玻璃看着像金属一样闪闪发光,并且不透明,同时还可以像金属一样导热和导电。 Scishow 精选系列 Well, when engineers invent… metallic glass, also known as amorphous metal. 当工程师发明玻璃合金的时候,也成为非晶金属的时候。 双语版 TED-Ed 演讲精选 The first metallic glass was made in 1960 from gold and silicon. 【加州理工学院】 金属玻璃最初是由金子和硅在1960年做出来的。 双语版 TED-Ed 演讲精选 In essence, they have to do with metallic glass' unique atomic structure. 从本质上来看,这些都归根于它奇特的分子结构。 科学60秒 听力 2013年11月合集 The sticker part of the system contains a tiny sliver of metallic glass. 贴纸部分的系统包含一个金属玻璃棉条。 TED-Ed(视频版) Metallic glasses also have an incredible ability to store and release elastic energy, which makes them perfect for sports equipment, like tennis racquets, golf clubs, and skis. 金属玻璃还有一个超牛的本领它可以储备并且释放弹性势能,这个优点让它们成为制造体育用品优越的材料。比如网球拍、高尔夫球杆,和雪杖。 TED-Ed(视频版) Well, a lot of scientists and technologists are getting excited about a relatively recent invention called metallic glass with both of those properties, and more. 因此,很多科学家和技术人员都为一个新发明而感到兴奋--金属玻璃,它同时拥有这两个优点! Scishow 精选系列 So, metallic glasses form when metal atoms are in this random arrangement, like when melted metal is cooled really, really quickly, before its particles can arrange themselves into a crystal. 所以,当金属原子随机排列时,合金玻璃就产生了,就像融化的金属,冷却地非常快,例子来不及排列成晶体。

非晶态金属 Amorphous metal(重定向自Metallic Glass)
![]() ![]() ![]() 非晶态金属是指在原子尺度上结构无序的一种金属材料。大部分金属材料具有很高的有序结构,原子呈现周期性排列(晶体),表现为平移对称性,或者是旋转对称,镜面对称,角对称(准晶体)等。而与此相反,非晶态金属不具有任何的长程有序结构,但具有短程有序和中程有序(中程有序正在研究中)。一般地,具有这种无序结构的非晶态金属可以从其液体状态直接冷却得到,故又称为“玻璃态”。所以,非晶态金属又称为「金属玻璃」(Glassy metal、Metallic Glass)、“玻璃态金属”、「液态金属」(Liquid metal)或大块金属玻璃(Bulk Metallic Glass,BMG)是一种具有较低冷却速度极限的非晶态金属,所以该种金属合金可以制备出尺度超过1毫米的金属片或金属圆柱。制备非晶态金属的方法包括:物理气相沉积、固相烧结法、离子辐射法、甩带法(连续铸造法其中一种)和机械法。

Amorphous metal 非晶态金属(重定向自Metallic Glass)
![]() An amorphous metal (also known metallic glass or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure. But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity. There are several ways in which amorphous metals can be produced, including extremely rapid cooling, physical vapor deposition, solid-state reaction, ion irradiation, and mechanical alloying. |
