1.Heat 2 has a higher resistance to cyclic impact loading and crack propagation than heats 1, 3, and 4.2.The optimal heat treatment for heat 2 to obtain the best resistance to cyclic impact loading with acting stress s=180 kg/mm2 is aging at 490° for 3 h, and aging at 510° for 3 h at lower stresses.3.Surface hardening (shotpeening) increases the resistance to impact loading more substantially for heat 1 than heat 3. |
