Purpose: The aim of the paper was investigation of the effect of Cu addition on GFA (Glass Forming Ability), structure, magnetic and mechanical properties of amorphous Fe-Co-B-Si-Nb alloy. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), transmission electron microscopy (TEM) and X-ray diffraction (XRD) method, measurements of magnetic...
The main aim of the paper was preparation of Fe-Co-based bulk amorphous alloy from high purity and industrial raw materials by an ejection copper mold casting method.
Purpose: The main aim of the paper was investigation of influence of geometry of rapid solidified rods on properties (structure, fracture morphology, microhardness) of Fe36Co36B19Si5Nb4 alloy. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), scanning electron microscopy (SEM), light microscopy (LM), X-ray diffraction (XRD) method, Vickers...
Purpose: The main aim of the paper was to investigate the structure and properties of the surface layers of the C45, 42CrS4, 42CrMoS4 steels after sulfonitriding at a temperature of 540 and 570°C. The thickness of zones occurring in the sulphonitric layer was defined just as their chemical and phase composition and microhardness. Moreover, abrasion resistance in the zones of sulfonitrided layers was...
