Properties Of Different Forms Of Steel example essay topic
Body A. First issue- Dislocations are the strength of all forms of steel. Each individual dislocation forms with another to create a "knot" that holds the matrices of atoms together. The more "knots" there are the stronger the material. The more carbon, up to 6.67%, that is added will create large obstacles that form tangles of dislocations, increasing the strength of the solid. B. Second issue- If we examine the decomposition o Austenite, steel, we see that different levels of % of carbon and temperature can create new variations to a not so simple compound. If we combine. 025% or more Carbon to iron and keep the temperature below 750 degrees Celsius we can make a very plastic material, ferrite, that is soft and has little brittility.
However, if the compound is heated up and there is less than 2% carbon added we come up with Martensite, which is very brittle but extremely strong to uniaxial force. C. Third issue- When we examine the cooling rates of carbon and iron to the amount of time it takes for them to reach a certain temperature, we can see different characteristics of each solid formed. For example, letter A is Martensite, it is cooled very rapidly and has a very isothermal transformation. If we examine letter B or C we see that they both pass through the Ferrite stages denoted by the hyperbolas bound to the regions Ae 1 and Ms. These have a less isothermal transformation and become more elastic. IV. Conclusion A. Each time I have discussed iron to steel to temperature we have been able to understand how different variables have explained the properties of different forms of steel. Each form has had some sort of impact on the world and even today more steel compounds are being formed that are lighter, stronger and more flexible B. Steel can be viewed from two stand points, the "I'll just sit back and enjoy the rewards of other people work" stand point, or the "That's pretty interesting, I think I can help engineers in their research and add to the work" stand point.
If research isn't for you, then your options are pretty narrow, but if there's any interest then get up and invent some new compounds!
