Project 1 In the first project: The team heat treated five pieces of steel alloy sheets which have the same carbon composition (0.78% C) by different heat treatment processes: Annealing, normalizing, water quenching, oil quenching and tempering. Then, they have checked the surface hardness using Brinell Hardness Tester, and they have got the results as shown in Table 1: Table 1. Hardness result for heat treated 0.78% C steel samples % C 0.78 0.78 0.78 0.78 0.78 Heat Treatment Annealing Normalizing Water quenching Tempering Oil quenching Hardness(HB) 30.0 33.0 63.0 49.0 41.0 Team leader asked you to explain every heat treatment process and discuss why same carbon content steels showed different hardness values? What was the effect of every heat treatment process on the properties of heat treated steel? Estimate the tensile strength and recommend the highest strength and most ductile ones?
