非晶合金的性能、形成机理及应用
Properties,Formation Mechanism and Application of Amorphous Alloys
摘要
Abstract
The development history of amorphous alloys is summarized,and their main performances are introduced including soft magnetic properties(magnetic flux density,permeability,coercive force and loss),mechanical properties(strength,hardness,toughness and wear resistance) and chemical properties(corrosion resistance).The advantages and disadvantages of the single roller quenching,double roller quenching,hanging drop melting extraction,and planar flow casting methods are compared.The forming mechanisms of amorphous alloys have been investigated from the structure,thermodynamics and kinetics.The characterization parameters of glass forming ability have been summarized and investigated.They include melting enthalpy ΔH,entropy of fusion ΔS,reduced glass transition temperature Trg,viscosity η,etc.As the amorphous alloys are more and more widely applied,the demand of the related functional or special materials will be more and more high.The development direction of amorphous alloys in our country is summarized in this paper.关键词
