摘　　要：研究了用单辊法制备非晶态合金条带时，冷却辊表面线速、熔体射流压力、喷射距离等参数对非晶态Ｆｅ３０Ｂ１１．４Ｓｉ３．５合金条带的形成、条带结构、性能及其退火脆化和晶化的影响。液淬工艺参数的合理配合下获得的足够高的液淬速率是得到非晶结构的关键，也是制备质量条带的决定因素。液淬速率愈高，条带厚度愈小，其脆化敏感性愈低。因此，高液淬速率下薄带的制备，有益于提高非晶态合金脆化抗力。非晶合金的晶化与液淬条件之间不存在直接的联系。The influence of linear speed of the roller substrate,ejecting pressure and distance of the molten jet on formation,annealing embrittlement and crystallization of amorphous Fe(80)B(11.5)Si(8.5)alloy made by single roller technique,have been studied in detail.High quenching rate which can be obtained by the rational combination of quenching parameters mentioned above is the key to gain noncrystalline structure and high quality amorphous strips.The higher the cooling speed,the thinner the strips are,and the lower the susceptibility of embrittlement. Experimental results show no direct relationship betwen the quenching condition and crystallization for Fe(80)B(11.5)Si(8.5) metallic glass.
