Question

A cylindrical rod of 1040 Steel originally 10.5 mm in diameter is to be cold worked by drawing to a final diameter of 8.5 mm. The circular cross section will be maintained during deformation. A cold-worked tensile strength in excess of 750 MPa and a ductility of at least 12 %EL are desired. Explain, with details and calculations, how this may be accomplished.

Answer 1

Answer:

Check the explanation

Explanation:

The desired Cold working (which is any process or procedure of metalworking in which the metal body is formed at a lower temperature beyond its recrystallization, typically at the ambient temperature.) tensile strength in excess of 750 MPa and a ductility of at least 12 %EL can be seen in the attached image below.
