WE43 is a high strength Magnesium Alloy which offers good mechanical properties both at ambient and elevated temperatures. 

The alloy mainly contains yttrium and neodymium. WE43 can be used successfully in temperatures up to 300°C and benefits from good corrosion resistance. The alloy is an excellent engineering solution in applications where weight reduction without compromising performance is required. Motorsport therefore is an obvious beneficiary as is the aerospace sector.

 

Magnesium alloys are promising in aerospace, automotive and electronic industries due to low density, high specific strength and excellent machinability. A rare earth element alloy(WE43) is studied in as cast and heat treated conditions. Multiscale characterization is conducted to understand the nanomechanical response using a nanoindentor and microscale behavior using tensile tests. Further, compressive characterization is conducted across six orders of strain rate magnitudes from 10-3 to 3x103 s -1 under the range of liquid nitrogen (-196°C) to room temperature (25°C). Based on the results, a constitutive model is developed to estimate the plastic behavior of as-cast WE43 and WE43-T5 at different strain rates and under different temperatures. In addition, dynamic properties are studied using a dynamic mechanical analyzer at 1-100 Hz loading frequencies and the temperature range from 35°C to 500°C. Only Yttrium-rich cuboidal phase and zirconium-rich phase were present in WE43-T5 alloy and the eutectic phase was absent. Also, the grain size was reduced due to the hot rolling process. The difference in microstructure reflects into the mechanical properties. WE43-T5 specimens have improved mechanical properties over the as-cast alloy. Two transition temperatures are found at 210 and 250°C based on the storage and loss moduli results. The Mg24Y5 peak is found in the high temperature x-ray diffraction results along with a new Mg12Nd peak at those two temperature points. The corrosion behavior, studied by 7-day immersion in 3.5% NaCl solution, shows that the heat treated alloy has significantly lower corrosion rate than the as-cast alloy due to the absence of the eutectic mixture in the microstructure. With rapidly growing applications of magnesium alloys, particularly with rare earth elements, this study is expected to provide critical data and structure-property correlations that will help the scientific community.

During early investigations the commercial-grade alloy WE43 was considered; more recently a variety of other alloy systems have been proposed. These include alloy modifications with aluminium (Erinc et al., 2010), calcium (Hassel et al., 2006) or lithium (Leeflang et al., 2010) as the primary alloying element. The main objective of these developments is to slow down the corrosion rate while maintaining or improving mechanical properties.

Efforts on manufacturing magnesium stent tube are reportedly based on the route used for conventional metal stents. This consists of:

1

Hot working of cast feedstock to obtain a solid rod.

2

Deep drilling of a hole in the rod to obtain a tube.

3

Multiple cold drawing and intermediate annealing of the tube to reduce diameter and wall thickness (Gerold and Müller, 2006).

The mesh is subsequently made by laser cutting, and the cutting edges are smoothed by electro-chemical polishing. An alternative route departs from this in that the hot-working process is conducted by direct extrusion with a mandrel and tubular billets, yielding seamless tube, and the drawing is done at elevated temperature, reducing the number of drawing steps (Hassel et al., 2006). Yet another route employs direct hot extrusion with a porthole die, which yields tubes directly from solid billets, followed by cold drawing (Werkhoven et al., 2011). Each of these methods has its particular assets and drawbacks.

Figure 13.8 shows some cut-off samples of the feedstock as well as of the semifinished tubes, together with a finished stent as manufactured according to this last- mentioned route. The basic reasoning behind combining an initial extrusion process with subsequent drawing to produce a stent tube is as follows. In hot extrusion, shape alterations imposed in a single processing step are high, but geometrical tolerances of the obtained tubes are limited and not high enough to reach the required accuracy of a finished stent tube. Thus hot extrusion is used to provide an intermediary shape. In drawing at room temperature (cold drawing), dimensional accuracy of the product is high, but the deformation that can be imposed in a single drawing step is limited so that a substantial reduction in tube diameter and wall thickness can only be achieved by repetitive drawing with progressively smaller tooling and by implementing intermediary heat treatments to restore the ductility of the material. Thus it is used to provide the final shape of the stent tube.
