Moving to another question will save this response. uestion 37 Materials with dislocations have lower shear strengths than materials with no dislocations. Is this true or false? Moving to another question will save this response. L
Which method do we use to monitor dislocation movements in tensile testing? How monitoring is done in this method, explain the working mechanism of the system in detail.
In an engineering application, the material is a strip of iron with a fixed crystallographic structure subject to a tensile load during operation. The part failed (yielded) during operation and needs to be replaced with a component with better properties. You are told that two other iron strips had failed at yield stresses of 110 and 120 MPa, with grain sizes of 30 microns and 25 microns respectively. The current strip has a grain size of 20 microns. The diameter of the rod is 1 mm and the load applied is 100 N. What is the yield stress of the new part C and would you recommend it for operation? Select one: a. 140.5, no Ob. 129.5, yes OC. 120.5 MPa, no O d. 133.5 MPa, yes O e. 123.5 MPa, yes

In deformation of metals, the slip and atomic dislocation mechanism is so significant because Dislocation motion hardens materials, while ductility reduces. The force required for slip is much less than the force required breaking the metallic bonds. Dislocation motion eases up the materials deformation. Open original

You are given three metal test samples, with the same chemical composition and differing grain sizes: A: 5.0, B: 10.0 and C: 20.0 microns. Samples A and B have been tested and have yield stresses of 142.4 MPa and 135.8 MPa (all numbers are rounded off to the 1st decimal point). Based on this information, which of the following values do you think will be the closest to the yield stress of Sample C? In calculating the answer, use the Hall-Petch relation between yield stress of a metal o vield and the grain size of the metal d, which is Oyield = 00 + kd¬1/2 where k and og are constants.
