1 Introduction
Alloys of the Fe–Zr system are widely used as functional materials, especially in
the nuclear industry. Stainless steel zirconium was developed for the manufacture of
containers for the storage of nuclear energy wastes [1, 2] and materials for nuclear
reactors and fuel cells [3]. The search for ways to improve the functional properties of materials of the Fe–Zr system continues. One possible way of modifying the
properties of materials is to change their atomic structure, in particular amorphization. It is known that homogeneity of amorphous materials improves their functional
properties, for example, corrosion resistance, mechanical, and magnetic properties.
Therefore, the amorphous metal alloys of the Fe–Zr system are characterized by a
wide range of unique physical properties, widely used as the latest functional materials; so the study of the peculiarities of their crystallization process has an important fundamental and applied value. Since amorphous alloys are thermodynamically
unstable systems, it is necessary to investigate the regularities of the crystallization
process under the influence of various external factors.
One of these factors is impulse laser treatment. The use of pulsed laser treatment
can significantly increase the rate of thermal impact on metals and alloys: up to
(10
4 –10
6 ) K/s using the most common pulsed and continuous technological lasers,
and in some cases up to (10
9 –10
10 ) K/s. Under such influence, crystallization must
occur instantaneously throughout the volume of the amorphous tape (explosive crystallization) [4]. The phenomenon of explosive crystallization in amorphous metallic
alloys is characterized by the intensive isolation of the latent heat of crystallization
