They are often anodized to improve their corrosion resistance. Nominal composition and typical room-temperature tensile properties of extruded magnesium alloys9‒12, R. Lapovok, Y. Estrin, in Advances in Wrought Magnesium Alloys, 2012. Université de Grenoble, 2013. To date, no magnesium alloys have been specifically designed for the TRC process but are variations of wrought magnesium alloys that have been successfully DC cast. Cpol-AZ31, chemically polished-AZ31; HAp-AZ31, HAp-coated AZ31. Formability of Mg alloys at ambient temperature is poor due to the insufficient number of active slip systems in the HCP lattice [2-7]. Firstly, the Mg alloy rod and the powder mixture of DCPD and Ca(OH)2 were placed into a polyethylene tube. The optimization of welding conditions is needed as a measure to prevent undercutting. Thus, by means of this technique, HA coatings could be bonded to Mg and its alloys with good adhesive properties (Onoki & Yamamoto, 2010). The focus in the present chapter has been on the effect of grain refinement by severe plastic deformation on superplastic properties of Mg alloys, as exemplified by alloys ZK60 and AZ31. One publication was found on the topic of hydrothermal hot pressing, which was devoted to the deposition of HA on AZ31 alloy (Onoki & Yamamoto, 2010). The investigated operation was the high-speed dry milling of a magnesium alloy with a polycrystalline diamond (PCD) cutting tool dedicated for light metal applications. Several laboratories have tried casting a range of magnesium alloys (other than AZ31) at … The Mg ion release increased almost linearly after 12 weeks. Table 7.9. Although AZ91 alloy has been cast using commercial TRC, the surface quality of AZ91 strip is still not suitable for sheet applications. MgF (Germany) and CSIRO (Australia) have also reported successful production of AZ alloys using semi-commercial scale twin roll casting lines. Successful commercial twin roll castings of AZ21, AZ31 and AZ61 alloys with and without calcium have been carried out by CSIRO (Allen et al., 2001), MgF (Engl, 2005) and POSCO/RIST (Jung et al., 2007, Park et al., 2011). L’alliage de magnésium AZ31 présente une très faible densité. The high-strength Zr-containing ZK60 was designed for applications in racing cars and bicycles, such as wheels and stems.10 The extrusion speed for making ZK60 tubes is extremely low, rendering it uneconomical for automotive applications. Indeed, the ligaments between the voids were found to still possess a substantial resource of ductility. Cast alloysare basically made by pouring the molten liquid metal into a mould, within which it solidifies into the required shape. However, there continues to be a global push to develop new wrought magnesium alloys produced via TRC that maintain a random texture orientation during deformation and hence have improved formability. 12.2.12 Undercutting is likely to occur in a wide bead made with a high power laser, at high pressure of an assist gas or under a large amount of flow of shielding gas from the front side of welding. Several laboratories have tried casting a range of magnesium alloys (other than AZ31) at the pilot scale. Recently, magnesium (Mg) alloys have received significant attention as a potential biomaterial for degradable implants, and this study was directed at evaluating the suitability of Mg for craniofacial bone screws. 321–326). 12.2. The alloy had similar strength to AZ31 but 50% higher ductility at temperatures below 200 °C and 20–50% higher maximum extrusion speed (Fig. Mathilde Forget. Achieving such structures was possible due to the use of back pressure during ECAP processing, which permitted reduction of the processing temperature. Of the commercial extrusion alloys, AZ31 is most widely used in non-automotive applications. lowered surface defects) as seen in Table 1.2, which was attributed to grain refinement and dispersion strengthening provided by the Mg12Ce particles and the altered texture (with c-axes of the grains less than 90° to the extrusion direction) that was obtained. The cast strips of these alloys were successfully rolled to produce Mg sheet with a minimum thickness of 0.12 mm. A phenomenological interpretation of delayed tensile failure appears to be possible on the basis of Hart’s instability criterion, which relates the resistance of a material against strain localisation to the strain hardening capability and the strain rate sensitivity of the flow stress.
