Each team will work independently, except in certain cases where data sharing between teams is required, as indicated by the instructor. Each team will maintain a laboratory logbook, where laboratory activities, observations, results, and analyses are recorded in journal format. Logbooks will be submitted and considered by the instructor as a part of the overall laboratory grade. All logbook pages should be numbered, and all entries should begin with the date, time, name of the person making the entry, and a refernce to the relevant lab exercise. Each team is required to prepare and submit a report for each exercise by the indicated due date. Reports are to be web-based and are to be submitted electronically, as directed by the instructor. The exercises are scheduled in one or two week periods, but lab work is generally "self-scheduled" and teams are welcome to work ahead if desired. However, students are responsible to be sure that the necessary training and instruction is received to ensure that all activities are carrieed out in a safe manner.

Each team will be required to submit one laboratory report for each laboratory exercise. All laboratory reports are to be formatted in html and ready for viewing with a standard web browser. As a minimum, reports should include: (i) title, (ii) team name and members, (iii) an introduction with background and motivation, (iv) a statement of objectives, (v) a description of the procedures used, (vi) a results section describing observations and data, (vii) analysis and discussion, (viii) conclusions, (ix) references, and (x) related links. Please use figures and tables effectively, providing interactive links to facilitate understanding. Grading will be based on (i) technical content, (ii) use of English, (iii) effective use of web platform.
All laboratory reports are to be subbmitted electronically by placing a folder with all html files and supporting files into the "Report Submission Dropbox" folder on the class file server. You will be given the location of this folder in class. Be sure that the submitted folder is clearly labeled with the Lab number, Team name, and year (e.g. Lab2_Tapirs_F07). Submissions must be made by 5pm on the posted dute date. Late reports will be graded for reduced credit (reduced 20% per day). All reports will be posted on the class website for public viewing.
Each team is required to complete a laboratory project, where the team will analyze an assigned engineered component, made from a ferrous alloy. The team is expected to (i) review/assess the design/service requirments for the component, (ii) characterize the microstructure (this may require analysis in several locations of the part), (iii) assess the processes used to manufacture the part, (iv) assess the alloy used for the part, (v) give a professional critique of the design, offering alternatives if appropriate, and (v) write a specification for purchasing the material to fabricate the component.
A short web-based report of part will be submitted by the indicated due date. This should . Clearly state the name of the part. Give a brief summary of what the part is intended to do, and include photographs of the part in the "as received" condition. If necessary, photographs or schematics showing how the part is used in the larger system should be included. From your investigation, include photographs of microstructure and any quantitative results (i.e. phase fraction, composition, hardness profiles, etc.). Based on your analyses and also on any relevant literature, state your best assessment of material and processes used to fabricate the component. In conclusion, include your critique of the design (including material selection and processing).
In addition to the web-based report, each team will be given 15-20 minutes to present their results in class. The presentations will be held during the last two weeks of the course and are intended to be interactive discussions that will also serve as a semester review.
