Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include m ...

Australian Aboriginal Artifacts

Most Aboriginal artefacts were multi-purpose and could be used for a variety of different occupations. Spears, clubs, boomerangs and shields were used generally as weapons for hunting and in warfare. Watercraft technology artefacts in the form of dugout and bark canoes were used for transport and for fishing. Stone artefacts include cutting tools and grinding stones to hunt and make food.
