过去两年,C-103铌合金板材的研制采用如下工艺:真空电弧熔炼—挤压锻造开坯—退火—冷轧—退火,轧制了两批不同厚度的板材,供给有关的工程单位做旋压、焊接、涂层用料,基本满足了试验之需。按照这个工艺生产的板材,其性能基本上达到了国外同一合金的水平。在广州会议上,引起了有关单位的注意。但此工艺仍有改进的必 In the past two years, C-103 niobium alloy sheet has been developed using the following processes: vacuum arc melting - extrusion forging billet - annealing - cold rolling - annealing, rolling two batches of different thickness plate, to supply the relevant engineering units do spin Pressure, welding, coating materials, basically meet the test needs. In accordance with the production of sheet metal, its performance basically reached the same level of foreign alloy. In Guangzhou meeting, aroused the attention of the relevant units. However, this process is still necessary for improvement
