College Pro To: Jon Paggett From: Russell Phillips Date: 10/12/00 Re: sharpness scrutiny Purpose Possibility of using hardness examination as a way to determine the amount of refrigerating wheeling in our 60-40 brass sheets Procedure We started with a settle on forefend, where we determined the dimensions using a dial measure out and calculated the hardness using a hardness tester. We thence stone- rimy-rolled the bar in olive-sized increments using a rolling mill, victorious the same measurements after we had completed approximately 5% cold ply. All of this data is on the attached sheet.
Results Results were as anticipate ? Hardness appeared to generally increase as cold work was done (see attached graph). There was a small defect in the experiment, the hardness does seem to decrease at active 15% - this is probably due to measurement flaw as the general trend should be valid passim the experiment. result My view on the situation is that we should not limiting our procedures at this poin...If you want to get a full essay, modulate it on our website:
