Explain the term Heat Treatment. How does heat treatment alter the mechanical properties of steel? B) What are the main steel types? C) What are the types of heat treatments

A cylindrical rod 500 mm long, having a diameter of 12.7 mm, is subjected to a tensile load of 30,000 N. The rod is to experience an elongation not more than 1.3 mm and FOS ≥ 1.5 setting yield strength as a criteria. Additional constraints to be met are max specific stiffness and %EL not more than 0.15. Which of the below listed materials are possible candidates? Justify your choice(s) by making a table of constraints.

5) Which of the following heat treatment is the softening process for steel? a. Cyaniding b. Carburizing c. Annealing d. Nitriding

Which is the correct definition of elastic deformation?       The behavior of a material when its size changes by the addition of heat.     The behavior describing a material's shape change under load that is self-reversing after the force is removed, so that the material returns to its original shape.       The behavior describing a material that deforms when subjected to stress and does not return to its original shape when the stress is removed resulting in permanent deformation.     Deformation caused by cleavage, where the material is actually pulled apart across atomic planes within the crystals or along the grain boundaries.
