When thinking of nails it is not often that the history of nails comes to mind‚ from the size to the evolution of nails throughout time‚ although without them the process of building would be totally different. Surprisingly‚ nails date back to the ancient times. Archaeologists have found hand made bronze nails from as far back as 3000 B.C. (Melchert‚ pg.1). The Romans made many of their nails from iron‚ which was harder‚ but many ancient nails have rusted away since

copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.

History of Iron and Steel I have researched the origin of hot metal cars for many years. In the very early years of iron production and later steel production historical is sketchy at best. Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education

This research paper is concerned with the effect of the pre corrosion on the mechanical properties‚ fatigue life‚ microstructure and weight density of Aluminium alloy 8011. 3.5 % NaCl solution was used to pre corrode the Aluminium alloy 8011 specimens. The specimens were kept in the solution for 100 hours. After the pre corrosion various test were performed to study the effects of pre corrosion on tensile strength and fatigue life. Aluminium alloy 8011 is used in the production of fins of various
