Unformatted text preview: 9000 Å and a density of 4.26 g/cm 3 , determine the number of precipitate particles per cm 3 . 12-31 A steel contains 94% pearlite and 6% primary cementite at room temperature. Estimate the carbon content of the steel. Is the steel hypoeutectoid or hypereutectoid? 12-56 A steel containing 0.95% C is heated to various temperatures above the eutectoid temperature, held for 1 h, and then quenched to room temperature. Using Figure 12-28 determine the amount and composition of any martensite that forms when the heating temperature is (a)728°C (b)750°C (c)780°C (d) 850°C...
