通常的金属材料都属晶体,而且绝大多数是多晶体,其基本性质受结晶组织、晶体结构、晶体缺陷和晶粒边界的特性所制约。长期以来,人们为获得非晶态金属曾作过许多尝试,但直到1960年才成功地利用超急冷技术,即在≥10~6℃/秒的冷却速度下,使熔融金属来不及结晶而急剧凝固为非晶态金属材料。非晶态合金具有许多特殊的物理、化学和力学性能,其强度、硬度和耐腐蚀性能等都超过常规的晶态合金,其特异的电磁性能则尤为人们所重视,因此发展迅速。1970年前后,世界上就已有非晶态
The usual metallic materials are crystalline, and most are polycrystalline, the basic properties of which are governed by the properties of the crystalline structure, the crystal structure, the crystal defects and the grain boundaries. For a long time, many attempts have been made to obtain amorphous metals. However, it was not until 1960 that the quench technology was successfully used, that is, the molten metal was too late to crystallize and rapidly solidified at a cooling rate of ≥10 to 6 ° C / sec For amorphous metal materials. Amorphous alloys have many special physical, chemical and mechanical properties, their strength, hardness and corrosion resistance than conventional crystalline alloys, the special electromagnetic properties are particularly valued people, so the rapid development. Around 1970, the world was already amorphous
