Alexandre de Freitas Silveira Eau Claire December 18th‚ 2012. Abstract: At this experiment‚ the composition of an alloy of Aluminum Copper was analyzed via X-Ray Fluorescence. From this‚ it was possible to construct a phase diagram a make some predictions about the possible phases presents at considering the 3 samples used in this experiment‚ the samples prepared at this experiment the sample as delivered was analyzed without any kind of treatment (sample I)‚ the sample with slow cool was prepared

"What are those?" I asked my mom‚ walking through Toys "R" Us and pointing at a large box. "Those are Legos‚ you can put them together and build things‚" she responded. I stared at them‚ repeating the name in my head. Legos. It was a funny name. They looked like colorful bricks with holes in them. "Can we get them?" I asked. Sure enough‚ we were carrying a box of them to the checkout section. Crazy as it seemed‚ the small blocks mesmerized me as a kid. The different colors‚ sizes‚ shapes‚ all

chapter dedicated to Phase I and Phase II of the tender evaluation process. Essentially in each phase you are doing risk identification and risk quantification. The assignment is to compare the two phases discussed and then answer questions that compare the two phases. Since each phase is designed to serve a different purpose‚ you can’t really say one phase is better than another. Both phases are important in order to understand the risks during the tender evaluation process. Phase I that is described

Paragraph 1 Quartz-type iron phosphate‚ FePO4‚ exists in different phases at different temperatures. At low temperatures‚ it exists in the α-quartz-type phase‚ while at high temperatures‚ it exists in the β-quartz-type phase. The α-β phase transition occurs at 980K. In terms of lattice symmetry‚ α-FePO4 exhibits a trigonal lattice system‚ whereas β-FePO4 exhibits a hexagonal lattice system. In terms of space symmetry‚ α-FePO4 belongs to the P3121 space group‚ while β-FePO4 belongs to the P6422 space

copper-gold system. Construct the phase diagram for this system and label each region. 9.22 For 5.7 kg of a magnesium-lead alloy of composition 50 wt% Pb-50 wt% Mg‚ is it possible‚ at equilibrium‚ to have α and Mg₂Pb phases with respective masses of 5.13 and 0.57 kg? If so‚ what will be the approximate temperature of the alloy? If such an alloy is not possible‚ then explain why. It is not possible. From the figure the maximum concentration of Pb in the α + Mg₂Pb phase filed is about 42 wt% Pb. 9
