Summary The invertebrate fauna of preconditioned wood that had been placed in the Acheron River, south-eastern Australia for 2, 5, 10, 20 and 30 days was compared with the fauna on natural logs. The…
Effect of nitriding on the resistance to fracture of high-strength maraging steel N18K9M5T
- E. Tsyrlin, Y. Lakhtin, V. Blinov
- Materials Science

- Materials Science
- 1 May 1983
Conclusions1.By ion nitriding of structural steels for 6–15 h it is possible to obtain a case depth of 0.2–0.4 mm with hardness HV 550-1100 and good mechanical properties.2.The most logical area of…
