Informative Speech 1587 Essay Example

up to 6.67%, larger obstacles are created, resulting in a tangle of dislocations and further enhancing the solidity's strength.

The second issue to consider is the decomposition of Austenite, specifically in steel. This involves the varying levels of carbon content and temperature, which can result in the creation of different variations of this complex compound. By adding 0.025% or higher carbon to iron and maintaining a temperature below 750 degrees Celsius, it is possible to produce a malleable material called ferrite. Ferrite is characterized by its softness and low brittleness. On the other hand, if the compound is heated and contains less than 2% carbon, it transforms into Martensite. Martensite is highly brittle but possesses exceptional strength against uniaxial force.

When studying the cooling rates of carbon and iron and the time it takes for them to reach a specific temperature, we observe distinct properties in the resulting solids. Martensite (letter A) undergoes rapid cooling and exhibits highly isothermal transformation. On the other hand, both letter B and C progress through the Ferrite stages, marked by hyperbolas surrounding the regions Ae1 and Ms. These stages involve a less isothermal transformation and result in increased elasticity.

IV. Conclusion

A. The properties of various forms of steel, ranging from iron to temperature, have been examined and their impact on the world has been significant. We have learned how different factors influence the characteristics of steel through this study. Currently, we are witnessing the emergence of newer steel compounds that are both lighter and more durable while maintaining flexibility.

There are two ways to approach steel: one is to passively appreciate the outcomes of others' work, while the other is to actively engage

in it and contribute to engineers' research. If you have no interest in research, your choices are limited. However, if you have any curiosity, take the initiative and create new compounds!
