Structure and Corrosion Behavior of Multiphase Intermetallic ZrCu-Based Alloys.

Zirconium-based alloys are highly regarded by the research community for their exceptional corrosion resistance, thermal stability, and mechanical properties. In our work, we investigated two newly developed alloys, ZrCuAlAg and ZrCuAlAg, in the form of ingots and ribbons. In the course of our investigation, we conducted a comprehensive structural and thermal analysis.

The effect of porous compliance bushings in a dental implant on the distribution of occlusal loads.

Porous dental implants are clinically used, but the mechanism of load distribution for stepped implant shaft surrounded by compliance bushings is still not known, especially for different bone conditions. The aim of the study was to assess the impact of the design of a dental implant with compliance bushings (CBs) on the occlusal load distribution during primary and secondary stability using finite element simulation (FEA), with a distinction between low and high quality cervical support under primary stability. The FEA of the oblique occlusal load transfer (250 N; 45°) was carried out for implants under variable bone conditions.

Structural characterization of newly-developed AlNiFeY and AlNiFeY alloys with amorphous matrixes.

The low glass-forming ability of aluminium-based metallic glasses significantly limits their development and preparation. This paper updates the current state of knowledge by presenting the results of structural studies of two newly-developed AlNiFeY and AlNiFeY alloys with a reduced aluminium content (< 80 at.%).

Evaluation of the biocompability and corrosion activity of resorbable CaMgZnYbBAu alloys.

Calcium-based alloys can be promising candidates for use as biodegradable implants because of attractive properties as mechanical, corrosive, and biocompatible. In the work, the biocompatibility authors discussed the results of the CaMgZnYbB (x = 0, 1, 2, 3 at.%) and CaMgZnYbBAu (x = 1, 2 at.

Study of crystallization mechanism of Al-based amorphous alloys by in-situ high temperature X-ray diffraction method.

The role of transition metals (TMs) addition on the formation and crystallization of amorphous AlTMsY alloys was described using in-situ high-temperature X-ray diffraction. The structural results were compared with differential scanning calorimetry and dynamical mechanical analysis to obtain detailed information about the nucleation and growth of crystalline phases. The performed analysis confirmed that Fe and Cu addition drastically changes the crystallization temperature and the phase composition of the fully crystallized alloys.

The Influence of Rapid Solidification on Corrosion Behavior of MgZnYbCaSr Alloy for Medical Applications.

Biodegradable magnesium alloys with Zn, Yb, Ca and Sr additions are potential materials with increased corrosion resistance in physiological fluids that ensure a controlled resorption process in the human body. This article presents the influence of the use of a high cooling rate on the corrosion behavior of MgZnYbCaSr alloy proposed for medical applications. The microstructure of the alloy in a form of high-pressure die-casted plates was presented using scanning electron microscopy in the backscattered electrons (BSEs) mode with energy-dispersive X-ray spectrometer (EDX) qualitative analysis of chemical composition.
