Prepare a report of the type set forth in the course syllabus. The report is to include the following data and analysis:
1. On a single graph, plot "Hardness" as the ordinate versus "Aging Time" as the abscissa for each aging temperature.
2. Discuss the effect of aging time and temperature on the effect of material hardness.
See the section on Precipitation Hardening in Reference [1] below.
3. Compare the hardness of Specimens 1 through 7 and elaborate on your observations.
The diffusion constant (Do) and activation energy (Q) of C in BCC Fe is 0.01 cm2/sec and 80kJ/mol respectively. In FCC Fe, the values are 0.21 cm2/sec and 148kJ/mol. At exactly 910oC these two phases can co-exist.
If it is known that the value of the stress exponent n for this alloy is 8.2, compute the steady-state creep rate at 1300 K and a stress level of 89 MPa.
what kind of metals are often recommended for use at low temperatures particularly when any sudden loading of the part
During the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the work input during this process. R(air)=287j/KgK
Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded. If the normal stress in each rod must be limited to 110 MPa, determine the minimum diameter D required for each rod.
the system on site is a pressure sand filter with a service curve. the filter is backwashed using the feed pump at a
determine the magnitude of the initial velocity of the bullet and the magnitude of the force exerted by the bullet on the block.
Discuss the factors beyond crystal structure, quenching and temperature that affect he results of a specimen in a Charpy V notch impact testing.
The link BD is a single solid bar with a width x thickness measuring 1.000 in. x 0.50 in. If the pins at A, B and D have a diameter of 0.375 in, determine the average normal stress in link BD when:(b) Fx = 0 and Fy =4.00 kips.
design a container using differentiation that has a volume of 2500 litres. it must use the minimum amount of material.
scenarioprepare a power point presentation and a short report relating to the capabilities of solidworks motion
Air enters a turbine at 40 kN/m2, 900 C, and leaves at 10 kN/m2. The flow is reversible and adiabatic. Inlet velocity is quite low and outlet velocity is 150 m/s through a cross-sectional area of 0.20 m2. Calculate the power output in kW.
