Non-Isothermal Analysis of the Crystallization Kinetics of Amorphous MgZnPt and MgZnAg Alloys.

In this study, thin ribbons of amorphous MgZnPt and MgZnAg alloys with potential use in biomedicine were analyzed in terms of the crystallization mechanism. Non-isothermal annealing in differential scanning calorimetry (DSC) with five heating rates and X-ray diffraction (XRD) during heating were performed. Characteristic temperatures were determined, and the relative crystalline volume fraction was estimated.

Influence of Heat Treatment Parameters of Austempered Ductile Iron on the Microstructure, Corrosion and Tribological Properties.

The influence of heat treatment parameters such as the annealing time and austempering temperature on the microstructure, tribological properties and corrosion resistance of ductile iron have been investigated. It has been revealed that the scratch depth of cast iron samples increases with the extension of the isothermal annealing time (from 30 to 120 min) and the austempering temperature (from 280 °C to 430 °C), while the hardness value decreases. A low value of the scratch depth and a high hardness at low values of the austempering temperature and short isothermal annealing time is related to the presence of martensite.

Crystallization Kinetics Analysis of the Binary Amorphous MgZn Alloy.

The aim of the study was to analyze the crystallization kinetics of the MgZn metallic glass alloy. The crystallization kinetics of MgZn metallic glass were investigated by differential scanning calorimetry and X-ray diffraction. The phases formed during the crystallization process were identified as α-Mg and complex MgZn phases.

Analysis of the Crystallization Kinetics and Thermal Stability of the Amorphous MgZnCa Alloy.

The aim of this study was to analyze the crystallization of the MgZnCa metallic glass alloy. The crystallization process of metallic glass MgZnCa was investigated by means of the differential scanning calorimetry. The glass-forming ability and crystallization are both strongly dependent on the heating rate.
