    摘要:

    為了快速實現(xiàn)突破、掌握大噸位鎳基合金轉子鍛件的制造關鍵技術并積累關鍵數(shù)據(jù),中國一重開展了700℃超超臨界汽輪機轉子用大截面鎳基合金轉子鍛件的試制。通過多次鐓拔的自由鍛造方式完成了直徑＞?600mm的試制件的制造。經(jīng)過檢測,鍛態(tài)晶粒度可達4~6級,性能熱處理態(tài)晶粒度可保持在1~2級,試制鍛件室溫抗拉強度>1000MPa,屈服強度>600MPa,沖擊AKV>45J,700℃抗拉強度>800MPa,屈服強度>500MPa,室溫和700℃的延伸率和斷面伸縮率均在20%以上,實現(xiàn)了大截面鎳基合金鍛件的均質化制造。

    Abstract:

    For rapid breakthrough, acquire the key manufacturing technology and accomplish key data accumulation, CFHI had manufactured a large-section Ni-base trial forging for 700 ℃ advanced USC powder plant. We successfully manufactured the rotor trial forging with a diameter of 660mm after several times of upsetting and drawing. Grain size of Ni-base alloy forging was 4-6 class and 1~2 class after heat treatment. The room temperature tensile strength can reach 1000MPa, yield strength can reach 600MPa, the impact energy is beyond 45J at different positions after heat treatment. The tensile strength can reach 800MPa, yield strength can reach 500MPa at 700℃.Tthe plasticity is more than20% at room temperature and 700℃.We realized the homogeneous manufacture of large section nickel base alloy forging.
