THERMAL TREATMENT OF HEATPROOF AND REFRACTORY ALLOY ?65???? |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: hardened billets of chromium-based alloy "?65????" is subjected to softening thermal treatment. Said treatment comprises annealing at 900°C with isothermal curing for 16 hours and slow cooling at the rate of 30-50°C/h after isothermal treatment to 650-550°C and then, cooling in air.EFFECT: higher hardness, stable properties at machining.1 tbl, 1 dwg, 1 ex |
