“…The master alloys were re-melted in a protective atmosphere using induction melting and then injected into the copper mold by the pressure casting method (Ref [11][12][13] to obtain glassy samples in the form of rods. In order to study the crystallization process, the samples in the ''as-cast'' state were annealed throughout the temperature range from 373 to 573 K with the step of 50 K. The investigated rods were annealed in the Thermolyne Furnace 6020C electric chamber furnace under a protective argon atmosphere.…”

The Mg 60 Cu 30 Y 10 and Mg 65 Cu 20 Y 10 Zn 5 bulk metallic glasses in the form of a rod 2 mm in diameter were successfully prepared by the conventional Cu-mold casting method. The addition of Zn caused the decrease in the crystallization and melting temperatures in comparison with the Mg 60 Cu 30 Y 10 alloy. The crystallization and melting temperatures are crucial factors that influence the casting process. An increase in annealing temperature leads to structural changes by the formation of the crystalline phases and lowers the compressive strength. These results obtained for the Mg-based bulk metallic glasses (Mg-BMGs) are important for some practical reasons, in particular, for developing the fabrication process. It has been shown that minor addition of an alloying element can change glass-forming ability and strength of the MgBMGs.

“…This very diversity in the arrangement of atoms in the volume of amorphous alloys causes their exceptional properties [1][2][3][4][5]. In contrast to the crystalline structure, where interactions between atoms have a long-range character, and their arrangement is symmetrical and maintains the angle translation with periodicity, in amorphous materials atoms are arranged chaotically and are subject to interactions of short or medium range [6]. Studies on the amorphous alloys have been conducted for over 50 years [7][8].…”

The paper presents the research results for the Fe 78 Co 2 Si 9 B 11 amorphous alloy, and after the process of annealing resulting only in the relaxation of the material. The structure relaxations occurring in the volume of test samples lead to the changes in their magnetic and mechanic properties. Therefore the studies on the effect of the structure defects on the properties of these type of materials are important. Understanding the processes occurring during the magnetizing of amorphous alloys can be helpful in the design of modern functional materials for special purposes. The main purpose of this elaboration was to determine the effect of the amorphous structure defects in the state after solidification and after heat treatment on the changes in the magnetizing process and in such parameters as the saturation magnetization and the coercivity field.

“…According to the research published in [8,9], one can indirectly observe sources of internal stresses in the form of structural defects in the volume of amorphous tapes. In Amorphous materials in the form of tapes, despite being discovered more than half a century ago, are still the object of interest for materials engineers and electro-technical industry.…”

Amorphous materials in the form of tapes, despite being discovered more than half a century ago, are still the object of interest for materials engineers and electro-technical industry. They possess a great application potential, and are constantly studied for new variations. Due to the different structure from the commonly manufactured textured FeSi sheets, FeCoB based amorphous alloys demonstrate very good, so called soft magnetic properties. This paper presents the results of studying the structure and magnetic properties of tapes of Fe78CoxSi11-xB11(X = 0 or 2) alloys of amorphous structure. In addition, the effect of Co alloy addition on the type of structural defects in the area of ferromagnetic saturation approach was examined. It was found that a small addition of Co affects the increase of saturation magnetization value, as well as the distribution of magnetization vectors within the stresses sources in form of structure defects.
