A cylindrical piece of steel 38 mm (1½ in.) in
diameter is to be quenched in moderately agi-
tated oil. Surface and center hardnesses must be
at least 50 and 40 HRC, respectively. Which of
the following alloys satisfy these requirements:
1040, 5140, 4340, 4140, and 8640? Justify your
choice(s).
Using the isothermal transformation diagram for a 1.13 wt% C steel alloy (Figure 10.39),
determine the final microstructure (in terms of just the microconstituents present) of a small
specimen that has been subjected to the following time-temperature treatments. In each case
assume that the specimen begins at 920°C (1690°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 103 s, then quench to room temperature.
(b) Rapidly cool to 775°C (1430°F), hold for 500 s, then quench to room temperature.
(c) Rapidly cool to 400°C (750°F), hold for 500 s, then quench to room temperature.
(d) Rapidly cool to 700°C (1290°F), hold at this temperature for 105 s, then quench to room
temperature.
(e) Rapidly cool to 650°C (1200°F), hold at this temperature for 3 s, rapidly cool to 400°C
(750°F), hold for 25 s, then quench to room temperature.
