Relationship between the corrosion behavior and the thermal characteristics and microstructure of Mg–0.5Ca–xZn alloys

Processing and microstructure–property relations of high-strength low-alloy (HSLA) Mg–Zn–Ca alloys

“…This is mainly achieved by applying a grain-refinement concept in which very fine and homogenously distributed Mg-Zn-Ca intermetallic particles (IMPs) restrict grain growth [4,7,8]. Whereas high zinc (Zn) content might be desirable because of its solid-solution hardening effect, it was recently demonstrated that this has a detrimental accelerating effect on the corrosion behavior of Mg-Zn-Ca alloys [9][10][11]. This is mainly due to the formation of Zn-rich IMPs, which act as cathodic sites [12,13].…”

The role of titania on the microstructure, biocorrosion and mechanical properties of Mg/HA-based nanocomposites for potential application in bone repair

“…Based on equation (6), the corrosion rate (P i ) can be calculated using the corrosion current density, i corr (mA/cm 2 ) [52,53] as follows:…”

Enhancement of the Mechanical Properties of an Mg–Zn–Ca Alloy Using High‐Pressure Torsion

“…Formation and phase composition of such particles have been studied earlier. [11,21] Their composition corresponds to the Ca 2 Mg 6 Zn 3 phase. In the initial microstructure, studied by TEM, these particles were observed as well (Figure 1b).…”

“…The dissolution rate and tensile strength of Mg-based alloys having different contents of Zn and Ca have been considered in ref. [7,11,12] In particular, it has been observed that the content of Zn should not exceed 1%, [7,11] and the content of Ca is recommended to be within 0.3%. [12] On the basis of these observations, the Mg-1%Zn-0.13%Ca has been selected for investigations.…”
