Which of the following statements is incorrect? Under creep and fatigue loading materials may fail at stress well below the Young's modulus of the mat During steady-state creep there is a balance between competing processes of strain-hardening and rece To reduce dislocation creep second phase precipitates can be introduced to the material. Choosing a material with a high melting temperature can offset creep. A viscoelastic material shows a combination of elastic response and a viscous flow.

Sorry I forgot to add the table. I think the answers will change this time The following creep data were taken on an aluminum alloy at 480 C (900 F) and a constant stress of 2.75 MPa (400 psi). Plot the data as strain versus time, a) then determine the steady-state or minimum creep rate. Note: The initial and instantaneous strain is not included. b) Identify at what time can a secondary creep region occur and at what time would it end to start the tertiary region in a creep curve: (see attachment).
Which is/are true of creep? Check the right answers a) creep is time dependent b) the units of creep are the same as that of stress c) with increasing temperature, the rupture lifetime decreases d) the creep curve consists of three regions e) none of the above

Given your understanding of what initiates and controls failure in materials, which of the following will increase the failure strength or lifetime of a test piece or component and why? a. Increasing the grain size so there are less grain boundaries to initiate failure b. Decreasing the temperature below the brittle-ductile transition temperature, to make it harder c. Decreasing the difference between the maximum and minimum stress values, as this effects the stress concentration factor d. Polishing to reduce surface defects e. Increasing its volume, to give a larger cross sectional area
