The influence of alloying and protracted isothermal storage on thermodynamics stability of amorphous alloys was investigated. By a highly sensitive dilatometric method the experiments for determining the temperature of the beginning of intense crystallization for the obtained alloys and post-isothermal storage at room temperature during seven years were conducted. The dependence of the temperature of the beginning of intense crystallization is analysed with regard to the amount of components in an alloy. It was revealed that the alloying of base binary alloys by the high temperature admixtures of a small concentration of Si, Nb, Mo, Mn, Ni, Co makes alloys more stable and slows the process of senescence of amorphous alloys.
