I originally did a preliminary test with Iron wool where we used a similar method but Test the iron wool was held over the flame by tongs and not contained within a crucible. We learnt from this experiment the importance of the crucible to contain all of the metal for an accurate test because the iron wool broke off as it heated and we were left with a lot of the iron wool on the bench mats around the Bunsen burner so our calculation of the mass of iron oxide was not accurate as we had not contained

MATSE 259 Solutions to classwork #8 1. For a 99.65 wt% Fe – 0.35 wt% C alloy at a temperature just below the eutectoid‚ determine the following: (a) The fractions of total ferrite and cementite phase. (b) The fractions of the proeutectoid ferrite and pearlite. (c) The fraction of eutectoid ferrite. (a) This part of the problem is solved by application of the lever rule employing a tie line that extends all the way across the α + Fe3C phase field. Noting that the alloy composition is 99

shaping using localized forces. This process has numerous advantages to the people using it as it produces a form of metal that is way stronger than a metal which has been fortified by a cast or a machine part. With regards to metals like steel and iron that are the most often used materials in the construction industry‚ this durability and strength is the main factor to their appeal and their functionality. Forgings involve great capital expenditure for tooling‚ machinery‚ personnel and facilities

Chemistry Report – How does Galvanizing prevent Rusting? Galvanization is the process of applying a protective zinc layer of coating to steel or iron to prevent rusting. The most common form of galvanization is hot-dip galvanization. Hot-dip galvanization is the process of coating iron or steel‚ which are less reactive‚ by passing the metal via a molten bath of zinc at high temperatures. Hence‚ when the solution gets exposed to the atmosphere‚ pure zinc reacts with oxygen to form zinc oxide
