GKN Sinter Metals Company pressed iron powders using a compaction pressure of 600 MPa to produced a cylindrical bearing which is 70 cm long and has internal and external diameters of 8 cm and 16 cm, respectively. Determine (a) the most appropriate pressing direction, (b) the required press tonnage to perform this operation, and (c) the final weight of the part if the porosity is 12%, given that the density of iron, ρ = 7.87 g/cm³. Assume shrinkage during sintering can be neglected

Expert Solution

Step 1

Given:

P=600 MPa

L=70 cm

Do=16 cm

Di=8 cm

density=7.87 g/cm³

Porosity=12 %

To determine

a) The most appropriate pressing direction,

(b) The required press tonnage to perform this operation, and
