“…The desired properties of these alloys can be directly correlated to the volume fraction of the LPSO phase, which increases with the rising alloying content, as reported in ref. [ 95 ]. There, a Mg-0.5Zn-2.2Y alloy was found to reach only 1% of the LPSO volume fraction, showing accordingly reduced properties when compared to the alloys with a higher element content.…”

Lean magnesium alloys are considered attractive candidates for easy and economical hot forming. Such wrought alloys, defined here as materials with a maximum alloying content of one atomic or two weight percent, are known to achieve attractive mechanical properties despite their low alloy content. The good mechanical properties and the considerable hardening potential, combined with the ease of processing, make them attractive for manufacturers and users alike. This results in potential uses in a wide range of applications, from rolled or extruded components to temporary biomedical implants. The characteristic behavior of these alloys and the optimal use of suitable alloying elements are discussed and illustrated exemplarily.

Mg-Alloys for Forging Applications—A Review

et al. 2020

View full text Add to dashboard Cite

Interest in magnesium alloys and their applications has risen in recent years. This trend is mainly evident in casting applications, but wrought alloys are also increasingly coming into focus. Among the most common forming processes, forging is a promising candidate for the industrial production of magnesium wrought products. This review is intended to give a general introduction into the forging of magnesium alloys and to help in the practical realization of forged products. The basics of magnesium forging practice are described and possible problems as well as material properties are discussed. Several alloy systems containing aluminum, zinc or rare earth elements as well as biodegradable alloys are evaluated. Overall, the focus of the review is on the process control and processing parameters, from stock material to finished parts. A discussion of the mechanical properties is included. These data have been comprehensively reviewed and are listed for a variety of magnesium forging alloys.

“…In the Mg-Zn-Y ternary system, Lee et al [9] reported that i-phase and W phase are the secondary phases when the Zn/Y ratio is between 1.8 to 6 in the Mg-Zn-Y system. When the Zn/Y ratio is between 0.3 and 1, the LPSO phase exists widely [5,[33][34][35][36]. Gröbner et al [11] examined Mg-Y-Zn ternary samples after DSC heating to 900 ℃ and slow cooling at a maximum rate of 5 K•min -1 ; the LPSO phase was observed in the samples when the Zn/Y ratio was 1.2 or 1 and it was absent when the Zn/Y ratio was 2.3 or 4.…”
