Abstract:
The aim of this work was to investigate and compare microstructure changes in squeeze cast heat treated Mg–2Y–1Nd–1Zn (WEZ211) and Mg–3Y–2Nd–1Zn–1.5Mn (WEZM3211) alloys. The WEZM3211 alloy was isochronally heat treated in 30 °C/30 min steps from room temperature up to 510 °C, the WEZ211 alloy was first isochronally heat treated in steps of 20 °C/20 min up to 440 °C, quenched and isochronally heat treated again.

Abstract:
Characteristic of standard sacrificial alloys on the base of aluminum is extremely low content of the cathode impurity elements. Due to this requirement, the stable electrochemical parameters and high efficiency of aluminum anodes is not always achieved.Falling characteristics of tread material can be attributed to their passivation - reduction of oxidation of the material of the tread due to the formation of a thick oxide layer on the surface of аnodic protector.This paper presents data as to how to stabilize the electrochemical properties of sacrificial zinc anodic materials that contain aluminum, zinc.

Abstract:
Optimization of conditions of heat treatment of Nd-Fe-B-based permanent magnets, prepared using the strip casting method, was carried out with the aim to enhance their coercivity HCJ and maximal energy product (BH)max, and to improve the shape of the demagnetization curve. The initial alloy with the chemical composition (for high-coercivity magnets) of Fe – 67.05; Nd - 19.50; B – 1; Dy – 6.00; Pr – 6.00; Cu – 0.15; Al – 0.30 (wt.%) in form of strips was submitted to hydrogen decrepitation and vibration milling.

Abstract:
Research in the field of magnetic materials based on Nd-Fe-B is focused on the improvement of certain magnetic characteristics by alloying of suitable elements (Co, Dy, Pr, Cu), extending the thermal stability of these permanent magnets, improving their corrosion resistance and the creation of nano-structure modifications. Magnets based on Nd-Fe-B are susceptible to corrosion, especially in humid atmospheres. [..]

Abstract:
For production bearing welds at resistance spot welding there is very important value about number of welds made by electrodes at which is created regular welding spot higher than certain minimal value and thus also efficient bearing capacity. During welding there is with increasing number of welded spots simultaneously also wearing of electrode working area, changing of conditions for creation weld joints and thus also their quality. [..]
