“…Applying powder metallurgy to produce an alloy means easy handling by combining each element so that modification on composition can be achieved and also be able to produce a near net shape alloy [8]. Powder metallurgy allows processing of non-porous alloy or even porous alloy [9]. Related to magnesium as biodegradable implant, porous or nonporous structure will have different properties in mechanical or in vitro properties.…”

Abstract.Magnesium and its alloy have gained a lot of interest to be used in biomedical application due to its biodegradable and biocompatible properties. In this study, sintering process in powder metallurgy was chosen to fabricatenonporous Mg-6Zn-1Ca (in wt%) alloy and porous Mg-6Zn-1Ca-10Carbamide alloy. For creating porous alloy, carbamide (CO(NH ) was added to alloy system as the space holder to create porous structure material. Effect of the space holder addition and sintering temperature on porosity, phase formation, mechanical properties, and corrosion properties was observed.Sintering process was done in a tube furnace under Argon atmosphere in for 5 hours. The heat treatment was done in two steps; heated up at 250 ºC for 4 hours to decompose spacer particle, followed by heated up at 580 ºC or 630 ºC for 5 hours. The porous structure of the resulted alloys was examined using Scanning Electron Microscope (SEM), while the phase formation was characterized by X-ray diffraction (XRD)analysis. Mechanical properties were examined using compression testing. From this study, increasing sintering temperature up to 630 ºC reduced the mechanical properties of Mg-Zn-Ca alloy.

Sintering Behavior and Mechanical Properties of Magnesium/β-Tricalcium Phosphate Composites Sintered by Spark Plasma Sintering

Mg/bioceramic composites fabricated by powder metallurgy technique have been explored for biodegradable load-bearing implants. Although sintering behavior including densi cation and reaction has a signi cant effect on mechanical properties of the composites, little studies have been conducted focusing on both sintering behavior and mechanical properties. In this study, Mg/10 and 20 vol.% β-tricalcium phosphate (β-TCP) composites were fabricated by spark plasma sintering, which achieved high densi cation. Distinct sintering behavior of Mg/β-TCP composites involving reaction was investigated by estimating relative densities during sintering, thermal analyses, X-ray diffractometry and auger electron spectroscopy. The results suggest that Ca solid diffusion into Mg during sintering resulted in melting and penetrating Mg into gaps between β-TCP particles, and nally led to high densi cation. The reaction between Mg and β-TCP produced MgO. Compression tests showed that Mg/β-TCP composites enhanced their mechanical properties compared with Mg sintered at the same route. That s because the high densi cation of Mg/β-TCP composites and high hardness of MgO potentially caused good load transfer from Mg-matrix to the formed MgO as reinforcement. The discoveries regarding the reactions can help the design of Mg/calcium phosphate composites including Mg/β-TCP composites.

“…Furthermore, sintering of magnesium powder 9 and the status of a MIM binder development suitable for magnesium is presented. Recently, magnesium alloys are also highlighted as appropriate biodegradable material for future orthopaedic applications, [10][11][12][13][14] because Mg-alloys provide elastic moduli and strengths matching those of bone tissue.…”

From titanium to magnesium: processing by advanced metal injection moulding

Metal Injection Moulding (MIM) is a good candidate for economic manufacturing of complex shaped components in high quantities. This is especially true for materials which are rather expensive and hard to form like titanium alloys. However, the high affinity to interstitial elements as oxygen and carbon presents a specific challenge with regard to powder purity, handling and sintering as well as to binder system and its removal. In this paper three examples for manufacturing high quality samples of advanced materials are shown in detail. These comprise an optimisation of the well known Ti-6Al-4V alloy with regard to MIM processing and fatigue resistance by adding 0.5 wt% boron powder in order to effect. a reduction in grain size. Secondly, MIM processing of intermetallic Ti-45Al-5Nb-0.2B-0.2C (at %) intended for application in turbine engines and turbochargers. And thirdly, the status of MIM of magnesium alloys is presented. In this case fabrication of biodegradable implants with adjustable porosity is the main motivation for the application of MIM.
