“…These properties are similar to the properties of a human bone (e.g., density, compressive yield strength, ultimate tensile strength). Magnesium alloy implants are moreover biocompatible and biodegradable [1][2][3][4][5][6][7][8][9][10][11]. As a result of chemical reactions with the biological environment non-toxic corrosion products are created on the surface of the implants.…”

Abstract:The electrochemical corrosion characteristics of AZ31 and AZ61 magnesium alloys were analyzed in terms of potentiodynamic tests and electrochemical impedance spectroscopy. The influence of the solution composition and material surface finish was examined also through the analysis of corrosion products created on the samples' surface after electrochemical measurements in terms of scanning electron microscopy using energy-dispersive spectroscopy. Obtained data revealed the differences in the response of the magnesium alloys to enriched Hank's Balanced Salt Solution-HBSS+ (with Mg 2+ and Ca 2+ ions) and Hank's Balanced Salt Solution-HBSS (without Mg 2+ and Ca 2+ ions). Both examined alloys exhibited better corrosion resistance from the thermodynamic and kinetic point of view in the enriched HBSS+. AZ61 magnesium alloy reached higher values of polarization resistance than AZ31 magnesium alloy in both the used corrosion solutions. Phosphate-based corrosion products were characteristic for the AZ31 and AZ61 alloys tested in the HBSS (without Mg 2+ and Ca 2+ ions). The combination of phosphate-based corrosion products and clusters of MgO and Mg(OH) 2 was typical for the surface of samples tested in the enriched HBSS+ (with Mg 2+ and Ca 2+ ions). Pitting corrosion attack was observed only in the case of enriched HBSS+.

“…Since only single α-Mg phase existed in the Mg-Zn alloy matrix, the result clearly indicates that Mg and Zn form a homogeneous solid solution due to diffusive reaction that takes place between pure metals without the formation of intermetallic compound or intermediate phase alloy (secondary solid solution) [4]. Further addition of Zn (more than 6 wt.%) into the host atom of Mg might lead to the detectable formation of intermetallic compound of Mg-Zn [4]. As for the both composites (SSP and DSP), incorporation of 8 wt.% of hydroxyapatite into Mg-Zn matrix alloy did not clearly observable in the diffractograms due to high intensity of Mg caused the low intensity of HAp to be concealed.…”

“…In most cases, the presence of secondary phase needs to be prevented due to its hard and brittle properties which inhibit the dislocation recovery and enhance dislocation density, thus leads to the decrement of the elongation [3].

“…Several researchers made use of the technique in the process of investigating the significant factors in experiments [20][21][22]. A fractional factorial design reduces significantly the number of runs required, particularly in screening experiments where many factors are studied in order to decide the relative importance amongst them.…”

Aluminum alloys for high-temperature applications have been the focus of many investigations lately. The main concern in such alloys is to maintain mechanical properties during operation at high temperatures. Grain coarsening and instability of precipitates could be the main reasons behind mechanical strength deterioration in these applications. Therefore, Al-Cu-Mg-Ag alloys were proposed for such conditions due to the high stability of Ω precipitates. Four different compositions of Al-Cu-Mg-Ag alloys, designed based on half-factorial design, were cast, homogenized, hot-rolled, and isothermally aged for different durations. The four alloys were tensile-tested at room temperature as well as at 190 and 250 ∘ C at a constant initial strain rate of 0.001 s −1 , in two aging conditions, namely, underaged and peak-aged. The alloys demonstrated good mechanical properties at both aging times. However, underaged conditions displayed better thermal stability. Statistical models, based on fractional factorial design of experiments, were constructed to relate the experiments output (yield strength and ultimate tensile strength) with the studied process parameters, namely, tensile testing temperature, aging time, and copper, magnesium, and silver contents. It was shown that the copper content had a great effect on mechanical properties. Also, more than 80% of the variation of the high-temperature data was explained through the generated statistical models.
