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

Manufacturing Technology – II MI 232 Instructor – Inderdeep Singh Spring 2011-2012 Foundry - Factory that produces metal castings • Casting: Process in which molten metal flows by gravity or other force into a mold where it solidifies in the shape of the mold cavity Steps: 1. Melt the material (metal) 2. Pour it into a mold 3. Let it freeze Refractory mold pour liquid metal solidify‚ remove finish Capabilities and Advantages • Versatile: complex geometry‚ internal cavities

and Evolution of Psychopathology and Abnormal Behavior Psychopathology has a long and troublesome history during which little was known about how disordered minds function and how to help individuals suffering from mental disorders. According to Alloy‚ Riskind‚ and Manos (2005)‚ the little knowledge that does exist about how ancient people treated abnormal behavior points to the belief that external‚ spiritual forces caused people to behave erratically. Possession by demons or evil spirits was considered

the literature‚ it says that‚ while the penny was in the boiling mixture zinc and NaOH solution‚ the zinc coated a thin layer around the penny and when you heated it over the Bunsen burner‚ the zinc and copper in the penny mixed and formed brass (alloy) which give the color of a gold to the copper. Qualitative Observations: The penny was dark brown before the experiment. At the end of the lesson‚ there were some

8/28/2011 Sand casting Metal Casting M t l C ti By S K Mondal Compiled by: S K Mondal Made Easy Sand casting uses ordinary sand as the primary mould material. The sand grains are mixed with small amounts of other materials‚ such as clay and water‚ to improve strength‚ mouldability and cohesive strength and are then packed around a pattern that has the shape of the desired casting. The pattern must be removed before pouring‚ the mold is usually made in two or
