Method for plastic-working ingots of heat-resistant alloy containing boron. |
| 摘要 |
<p>There is disclosed a method for plastic-working a heat-resistant alloy containing boron, which is in the form of an ingot. The ingot of the alloy is first subjected to hot working. Subsequently, annealing, acid-washing and cold working are carried out on the hot-worked blank material to provide a worked product. The hot working and the annealing are both carried out at a temperature ranging from 1,000 DEG C to 1,150 DEG C.</p> |
