Learning outcomes
KNOWLEDGE AND UNDERSTANDING:At the end of the course, students will be able to master the metallographic sample preparation procedures and some of the metal microstructure stereology methods
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:At the end of the course, students will have to: 1. acquire the skill to select a specific thermal treatment for steels or cast irons intended to optimize given mechanical properties; 2. Acquire the skill of the specimen preparation for optical microscopy; 3. To master the application of stereology methods to the acquired optical micrographs; 4. Acquire the ability to perform hardness and micro-hardness tests
TRANSVERSAL SKILLS:The proposed student reports on the laboratory experiences will develop a self-supporting knowledge of the major arguments of the course, it will also contribute to develop a synthesis skill of the students.
Program
pecimen preparation for optical and electron microscopy. Optical microscopy. Atomic force microscopy (AFM). Scanning electron microscopy (SEM and FEGSEM). Transmission electron microscopy (TEM). Hardness and micro-hardness tests. Nanoindentation. Thermal treatments. Elements of Stereology.
Development of the examination
LEARNING EVALUATION METHODSOral and with a Laboratory Report. Students, divided in groups, are asked to write a laboratory report on the basis of the laboratory guided experience. This will be evaluated, and the overall mark is the average of the oral and this report mark.
LEARNING EVALUATION CRITERIALab report evaluation and oral exam on the class topics.
LEARNING MEASUREMENT CRITERIAThe student have to show a full ability to solve problens to which he will be faced during the laboratory experience, it will have to learn how to write a lab report, and will have to show a full knowledge of the course topics (for the oral exam).
FINAL MARK ALLOCATION CRITERIAThe lab report will be evaluated on a 30 point basis. The oral part of the exam will be organized on a 3 query basis. Each query will be evaluated from 0 to 10 points. The overall mark is the average between the lab report mark and the oral mark.
