Microscopic Examination

MICROSCOPIC EXAMINATION OF METALS
In this experiment, our aim is examining the microstructure of metals. By studying
microscopic structures of metals, we determine which material fits best to a given
application. We used the most common method, optical technique, to examine the
microstructure.

We used a small specimen cut from the metal to be examined. To be able to see the
structure clearly, we first cleaned and polished the specimen. First we start polishing
with emery paper no: 1 and some finer grades. One should be careful about the coarse
abrasive particles and striations from them. Cleaning and rotating the specimen 90° during
the transfer can prevent these. The next step is polishing, yet washing the sample before
polishing gives a more successful result. Finally, we polished the specimen on a rotating
cloth covered with an effective abrasive like Al2O3-Water suspension. We kept polishing
until we obtained a mirror like face.

After we finished polishing, the crystalline structure of the specimen, any cracks, seams,
non-metallic inclusions and inhomogenities, could be revealed. Before start etching we
first applied mounting process. In this step we used a matched die set. We placed our
sample into the die set in the way that the rough face of the specimen was the lower
surface and the polished face looked upward. We filled the die cavity with Bakelite and
then we transferred our die to a mounpress. Mounting not only protects our sample but also

    Computer Communications Communications. I could barely spell the word, much less comprehend its meaning. Yet when Mrs. Rubin made the announcement about the new club she was starting at the junior high school, it triggered something in my mind. Two weeks later, during the last month of my eighth grade year, I figured it out. I was rummaging through the basement, and I ran across the little blue box that my dad had brought home from work a year earlier. Could this be a modem? I asked Mrs. Rubin a

    Macbeth Essay I am going to prove that in the play Macbeth, a symbol of blood is portrayed often(and with different meanings), and that it is a symbol that is developed until it is the dominating theme of the play towards the end of it.

Perhaps the best way to show how the symbol of blood changes throughout the

    Machiavelli The term Machiavellian refers to someone who is unscrupulous, cunning, cynical, and unprincipled (Goods 1998). Many scholars agree that this particular adjective would have dismayed Niccolo Machiavelli, the man from whom the term is derived.

His most famous work The Prince has

The only chemical that can dissolve or even tarnish pure gold is "royal water", a mixture so fiendish few of us are ever likely to encounter it and those who do will have other things to wor
  • Misunderstood
    Misunderstood The definition of a good father is as individual as the individuals involved themselves. A good father is able to support his children’s strengths, along with being able to help them overcome their weaknesses. He is able to do this without appearing to be a know-it-all. The ability to show by example how to live life, while not being afraid to make mistakes and not to be perfect all the time are also very important characteristic. Atticus was by that definition a very good father.
