Experiment: Heat Treatment - Quenching & Tempering

specimens after cleaning one of the surfaces with sand paper to remove any hard carbon deposits that may have formed on the surface. Take 5 readings on each sample. b. Determine the Charpy impact strengths of all the heat treated specimens (make sure the Impact Testing Machine is rezeroed after each test!).

A fundamental study on the flow past a circular cylinder ...

Flow patterns generated around a circular cylinder immersed in a uniform flow are shown in Figure 1 (Hughes & Brighton, 1999). In relation to the flow around an object, a combination of a uniform flow with a circular cylinder will be the simplest case. The pattern of this flow varies depending upon the Reynolds number.

Stress-Strain Data with EXCEL

Sep 09, 2002 · The Tensile Test This example uses data recorded during tensile testing on an Instron testing machine. The specimen is made of 6150 Steel. During the test, the load increases to a maximum value, then decreases. Eventually the specimen breaks. Information about the specimen and testing conditions are recorded in a header file.
