Experiment 7: Relative Density Laboratory Report Marella Dela Cruz‚ Janrho Dellosa‚ Arran Enriquez‚ Alyssa Estrella‚ Zacharie Fuentes Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment was conducted to show the different methods on how to determine an object’s composition through its density and to determine an object’s density by displacement method and the Archimedes Principle. Results show that. The materials

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

(a)Ferromagnetic materials: Ferromagnetic materials have a large‚ positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains‚ large numbers of atom’s moments (1012

visible with the aid of a scanning electron microscope. Not all engineering materials exhibit striations. They are clearly seen in pure metals and many ductile alloys such as aluminum. In steels‚ they are frequently observed in cold-worked alloys. Figure 2 shows examples of fatigue striations in an interstitial-free steel and in aluminum alloys. The most accepted mechanism for the formation of striations on the fatigue fracture surface of ductile metals‚ is the successive blunting and re-sharpening
