Using the isothermal transformation diagram for a 0.45 wt% C steel alloy (Figure 10.40), determine the final microstructure (in terms of just the microconstituents present) AND approximate percentages of the microconstituents that form in a small specimen that has been subjected to the following time-temperature treatments. In each case assume that the specimen begins at 845°C (1550°F), and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure. (a) Rapidly cool to 250°C (480°F), hold for 10^3 s, then quench to room temperature.
(b) Rapidly cool to 700°C (1290°F), hold for 30 s, then quench to room temperature.
(c) Rapidly cool to 700°C (1290°F), hold at this temperature for 10^5 s, then quench to room temperature.
(d) Rapidly cool to 400°C (750°F), hold for 500 s, then quench to room temperature.

Plot the data and determine (a) the transition temperature of each (defined by the mean of the absorbed energies in the ductile and brittle regions); and (b) the transition temperature of each (defined as the temperature that provides 50 J of absorbed energy)arrow_forwardThe assembly consists of a brass shell (1) fully bonded to a ceramic core (2). The brass shell [E = 86 GPa, α= 18 × 10−6/°C] has an outside diameter of 33 mm and an inside diameter of 27 mm. The ceramic core [E = 320 GPa, α= 2.5 × 10−6/°C] has a diameter of 27 mm. At a temperature of 15°C, the assembly is unstressed. Assume L = 320 mm.

Thecomponent has a length of 120m (at a temperature of -10°C) and is to be exposed to a temperaturerange of -10°C to 55°C. In order to calculate the gaps which need to be left between the sections michael'scustomer needs to determine the maximum length which each railway track section will expand to andmichael have been asked to carry out the calculation for them. michael have also been instructed to determinethe percentage change in volume and surface area when exposed to the same initial and finaltemperatures. The customer has informed him that the cross sectional profile of the railway track isrectangular and of breadth 14cm and height 32cm.
