Microscopic Boundary Examination :: essays research papers

MICROSCOPIC EXAMINATION OF METALSIn this experiment, our aim is examining the microstructure of metals. By studying microscopic structures of metals, we determine which sensible fits best to a given application. We employ 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 foremost cleaned and polished the specimen. First we start polishing with emery paper no 1 and some finer grades. star 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 wash the judge before polishing gives a more successful result. Finally, we polished the specimen on a rotating cloth covered with an effective abrasive alike(p) Al2O3-Water suspension. We kept polishing until we obtained a mirror like human face.After we finished polishing, the cr ystalline 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 by making its base flat and stable helps us while we are examining the sample under the microscope. In etching process, depending upon chemical composition, energy content and grain orientation, we determine the grain boundaries and the presence of chemically different phases. To reveal these micro structural details of the polished mount we used an etchant like 1% Nital.

The Bluest Eye :: essays research papers

&9Misdirection of Anger "Anger is better than shame. thither is a sense ofbeing in anger. A reality of presence. An awareness of worth."(50) This is howmany of the blacks in Toni Morrisons The Bluest Eye felt.

In this manner, they kept their angercirculating among themselves, in effect oppressing themselves, at the same timethey were being oppressed by the white people. Pecola Breedlove was a unseasonedblack girl, growing up in Lorain, Ohio in the early 1940s. Her life was one of themost difficult in the novel, for she was almost totally alone. She suffered themost because she had to dare having others anger dumped on her,internalized this hate, and was unable to get angry herse lf. Over the course ofthe novel, this anger destroys her from the inside. When Geraldine yells at herto get out of her house, Pecolas eyes were fixed on the " delightful" lady and her"pretty" house. Pecola does not stand up to Maureen Peal when she made fun ofher for seeing her dad naked but instead lets Freida and Claudia fight for her. instead of getting mad at Mr. Yacobowski for looking down on her, she directedher anger toward the dandelions that she once thought were beautiful. Thedandelions also represent her view of her blackness, once she may havethought that she was beautiful, but like the dandelions, she now follows themajorities view. However, "the anger will not hold"(50), and the feelings soongave way to shame. Pecola was the sad product of having others anger set(p)on her "All of our waste we dumped on her and she absorbed. And all of ourbeauty, which was hers first and which she gave to us"(205). The other blackpeople felt beautiful si de by side(p) to her ugliness, wholesome next to her uncleanness,her poverty made them generous, her weakness made them strong, and her painmade them happier. In effect, they were oppressing her the same way the whiteswere oppressing them. When Pecolas father, Cholly Breedlove, was caught asa teenager in a bowl with Darlene by two white custody, "never did he once considerdirecting his hatred toward the hunters"(150), rather her directed his hatredtowards the girl because hating the white men would "consume" him.
