“…The specific mechanical properties of some of the Mg composites (reviewed in this research) developed using microwave processing are listed in Table 18. [19][20][21]27,[29][30][31][32]34,[40][41][42][43][44] It highlights the potential of magnesium (nano)composites developed using microwave processing method in terms of high strength and ductility as par with some of the commercial alloys based on AZ and WE series. [19][20][21]27,[29][30][31][32]34,[40][41][42] The achieved mechanical property (0.2% YS and UTS) improvement was attributed to Orowan strengthening, grain refinement and internal strain and thermal stresses between reinforcements and matrix.…”

Orowan strengthening occurs due to the presence of finely distributed nanosized reinforcements that hinders the movement of dislocations.…”

Magnesium (with density, r ¼ 1.74 g cc 21 ) being ,35% lighter than aluminium and ,75% lighter than steel is an attractive and a viable candidate for the fabrication of lightweight structures. Being the designers' choice for weight critical applications, extensive research efforts are underway into the development of magnesium metal matrix composites (Mg-MMCs) through various cost effective fabrication technologies. In recent years, there has been a progressive advancement in utilising the microwave energy to consolidate powder materials, and the present study accentuates the use of energy efficient and environment friendly microwave sintering process to synthesise magnesium based composite materials. The processing advantages of the innovative and cost effective microwave assisted bidirectional rapid sintering technique followed by hot extrusion are first briefly introduced. Subsequently, the properties of various Mg-MMCs containing nanosized ceramic/metal particles, synthesised using this technique, are presented. Special emphasis has been made on the commending mechanical properties displayed by the nanoparticle reinforced Mg composites (Mg-MMNCs). Finally, an account of continuing research initiatives related to the development of novel lightweight Mg composites containing amorphous reinforcement is also highlighted.

“…Moreover, they used the magnesium alloy AZ91 to realize samples with a relative density up to 99.5% [ 16 ]. However, the problem with aluminum as an alloying component is its poor biocompatibility, which led to increased process development activities for the use of WE43, which has been used in conventionally manufactured resorbable implants previously [ 15 , 17 ].…”

Additive manufacturing (AM) has become increasingly important over the last decade and the quality of the products generated with AM technology has strongly improved. The most common metals that are processed by AM techniques are steel, titanium (Ti) or aluminum (Al) alloys. However, the proportion of magnesium (Mg) in AM is still negligible, possibly due to the poor processability of Mg in comparison to other metals. Mg parts are usually produced by various casting processes and the experiences in additive manufacturing of Mg are still limited. To address this issue, a parameter screening was conducted in the present study with experiments designed to find the most influential process parameters. In a second step, these parameters were optimized in order to fabricate parts with the highest relative density. This experiment led to processing parameters with which specimens with relative densities above 99.9% could be created. These high-density specimens were then utilized in the fabrication of test pieces with several different geometries, in order to compare the material properties resulting from both the casting process and the powder bed fusion (PBF-LB) process. In this comparison, the compositions of the occurring phases and the alloys’ microstructures as well as the mechanical properties were investigated. Typically, the microstructure of metal parts, produced by PBF-LB, consisted of much finer grains compared to as-cast parts. Consequently, the strength of Mg parts generated by PBF-LB could be further increased.

Magnezyum alaşımları özellikle düşük yoğunlukları ve yüksek spesifik dayanımları nedeniyle günden güne daha geniş alanlarda kullanım imkanı bulmaktadır. Bu alaşımların endüstriyel uygulamalarda daha yüksek oranda kullanımının önündeki en büyük engel hegzagonal sıkı paket olan kristal kafes yapısından dolayı geleneksel yöntemlerle plastik deformasyon işlemlerinin zor olmasıdır. Bu zorlukların üstesinden gelmek için kullanılabilecek yöntemlerden biri toz metalurjisi (TM) ile üretimdir. Bu çalışmada ticari olmayan bir tozmetal magnezyum alaşımı toz metalurjisi yöntemiyle geliştirilmiş ve geliştirilen alaşımın mikroyapısal özellikleri incelenmiştir. Çalışma sonucunda magnezyuma yapılan Sn ilavesi ile tane boyutunda ve dolayısıyla sertlik değerlerinde yükselme tespit edilmiştir. Ayrıca magnezyuma yapılan Sn ilavesi ile Mg2Sn fazının oluştuğu görülmüştür. Kalay ilavesi ile daha düşük sıcaklıklarda yapılan sinterleme işlemlerinde yüksek yoğunluk değerlerine ulaşılabildiği tespit edilmiştir.
