The Relationship

Mg alloys show limited room temperature formability compared to its lightweight counterpart aluminium alloys, which is a main obstacle in using this metal for most of the structural applications. However, it is known that grain refinement and texture control are the two possibilities for the improvement of formability of magnesium alloys. Amongst the approaches attempted for the texture weakening, additions through of rare-earth (RE) elements have been found most effective. The relationship between the texture and ductility is well established. In this paper, the effect of rare earth addition on texture weakening has been summarized for various magnesium alloys under the two most common modes of deformation methods.

Microstructural Studies

Magnesium alloys containing rare earth elements have better properties in terms of of formability, strength and corrosion resistance. Due to the tight supply situation these elements should be partially or complete substituted, for example by calcium. Microstructural studies of casted alloys of new compositions, and the influence of various heat treatments on their microstructure are investigated. The mechanical properties of the rolled materials are also presented and discussed. The works presented in this paper are results of the ongoing BMBF project SubSEEMag.

Element Addition

The magnesium alloys with rare earth element addition are widely used as nodularizer recently. However, the low absorption rate of Mg and lots of white smog during burning become critical issue. In this paper, a new type of iron coated nodularizer is developed to solve the above problems and reduce the production cost. The microstructure and mechanical properties also investigated.

Magnesium Casting

Magnesium alloys are widely used in automotive and aerospace industries due to their great connection of low density and good mechanical properties. They are also characterized by good castability and weldability. Their weak high temperature properties and corrosion resistance, led to development of magnesium alloys containing rare earth elements. Casting is the most popular way of manufacturing magnesium elements. However, there is a lack of investigations concerning impact of different factors on fluidity of these alloys. This paper presents results of investigations on influence of pouring temperature on castability and microstructure of QE22 and RZ5 magnesium alloys. In case of QE22 alloy, the filling length of the liquid alloy increased with the increasing pouring temperature. In RZ5 no such dependence was noted. This is probably caused by oxide films in the structure of material. Grain refinement and eutectics volume fraction also didn’t present correlation with pouring temperature.

Re Elements

Magnesium alloys are the lightest structural metal. The lightness is the main reason for the interest for Mg in various industrial and clinical applications, in which lightweight structures are in high demand. Recent research and developments on magnesium Mg alloys are reviewed. A particular attention is focused on binary and ternary Mg alloys consisting mainly of Al, Zn, Mn, Ca and rare earth (RE) elements. The effects of different alloying elements on the microstructure, the mechanical and the corrosion properties of Mg alloys are described. Alloying induces modifications of the microstructural characteristics leading to strengthening mechanisms, improving then the ductility and the mechanical properties of pure Mg.

Mechanical Properties And Corrosion

Rare earth magnesium alloys and Mg-Zn-Cu alloys were prepared by gravity casting and direct squeezing casting respectively, and the corrosion performances of three kinds of Mg-Zn-Cu alloys were compared in this paper. The results indicate that adding rare earth elements and direct squeezing casting process can significantly increase the mechanical properties of magnesium alloys, and aluminum can improve the corrosion resistance of magnesium alloys.
