3. For a steel alloy it has been determined that a carburizing heat treatment of 10 h duration will raise the carbon concentration to 0.45 wt% at a point 2.5 mm from the surface. Estimate the time necessary to achieve the same concentration at a 5.0 mm position for an identical steel and at the same carburizing temperature. [40]
2.4 For a steel alloy it has been determined that a carburizing heat treatment of 5-h duration will raise the carbon concentration to 0.45 wt% at a point 2.5 mm from the surface.

Current Attempt In Progress For a steel alloy it has been determined that a carburizing heat treatment of 17 h duration at 700'C will raise the carbon concentration to 0.39 wt at a point 3.9 mm from the surface. Estimate the time necessary to achieve the same concentration at a 7.7 mm position for an identical steel and at a carburizing temperature of 1030°C. Assume that Dois 3.1 * 10 m/s and Q, is 103 kJ/mol. e Textbook and Media...
6. (10) For a steel alloy at 900'C, it has been determined that a carburizing heat treatment of 8 hours will raise the carbon concentration to 0.35 W% at a point 0 mm from the surface. If the same steel is left in the furnace for 150 hours, to what depth below the surface will there be a carbon concentration of 0.35 wt%? Must show work and support any assumptions.

A single crystal of Al has the FCC crystal structure and is oriented such that a tensile stress is applied parallel to the [010] direction. If the critical resolved shear stress for this material is 0.2 MPa, calculate the magnitude(s) of applied stress(es) necessary to cause slip to occur on the (111) plane in each of the [1̅10] [1̅01] [011̅] Also, which of these slip systems is “preferred” for slip?
2. Consider a single crystal of some hypothetical metal that has the BCC crystal structure and is oriented such that a tensile stress is applied along a [121] direction. If slip occurs on a (101) plane and in a [111] direction, compute the stress at which the crystal yields if its critical resolved shear stress is 2.4MPa.

2. A steel bar 100 mm long and having a square cross section 20 mm on an edge is pulled in tension with a load of 89,000 N and experiences an elongation of 0.10 mm. Assuming that the deformation is entirely elastic, calculate the elastic modulus of steel. Give your answer in GPa. 3. A zinc single crystal is being pulled in tension with the normal to its basal plane (0001) at 60° to the tensile axis and the slip...
