“…Rani et al prepared thin films of CdSe:Zn using Electron Beam (EB) evaporation technique [4]. Amiour et al investigated the microstructure and the shape memory related properties of Cu-Zn-Al alloys [5]. Their results revealed that any modification in the composition of the alloy led to the generation of new phases.…”

It was the invention of fire, which has given a new shape in the development of humankind. Use of fire to modify metallic structure assisted to have desired shape of raw metal. The necessity of metallic weapon secured the prehistoric life of ancient human. Relic evidence highlighted the fact that, the use of metalwork has an illustrious history, which started with Copper (9000 BC) then different other metals and alloys came into use. With the innovative mind of human being, the use of metal was not limited only in weapon making; different utensils and shelter equipment also got the metallic touch. This feat made them a regional superpower for years to come. Thus, at step, the methodology of metallurgy underwent multiple refinements. Powder Metallurgy (PM) is one such refinement which is concerned with production of metals in their powder form and molding them into various shapes. This form of metallurgy was incorporated into the echelon of metallurgical techniques at around 3000 BC and has seen numerous advancements since then. However, research and study on Metallurgy and Mining is a timely need of present era to provide and meet the global need of metal. The Faynan region of Southern Jordan, home to the largest Copper deposits in Southern Levant, was at the epicenter of an industrial revolution during the Iron Age (1200-500 BC). To this day, ancient smelting sites populated with huge mounds of industrial slag can be found in Fanyan. One such site is Khirbat al-Jariya (KAJ). Liss et al. investigated the history of metal production at KAJ by excavating a slag mound [1]. The authors sampled geo-referenced slag specimens corresponding to the various strata of the dig and subjected it to XRay Fluorescence (XRF) analysis. The authors observed that the older samples were rich in Copper, whereas the newer ones had approximately 70% less Copper content indicating a shift towards more advanced and ergonomic metallurgical techniques. Further, it was revealed that all the sample ores were "self-fluxing" as they were rich in manganese. The fact that, the Iron Age populations of Faynan were aware of the "self-fluxing" properties of these ores and specifically chose them for smelting, hints towards a technologically sound populace. The properties and microstructure of alloys can be regulated by micro-alloying with Silicon or Copper. SiC or CuC reinforced alloys are usually prepared by casting methods such as gravity casting, infiltration casting, transfer molding etc. The downside of this method is the heterogeneous distribution of SiC particles. The Powder Metallurgy (PM) method is an alternate method of preparing SiC particle reinforced Al-Mg-based alloys. The properties and microstructure of SiC reinforced Powder Metallurgy (PM) AlMg-based alloys are influenced by the SiC particle size and volume fraction, the sintering process used, and the matrix alloy composition. Shen et al. studied the influence of solution treatment temperature and SiC particle content on the mechanical properties, the corrosive behavior, and micros...
