摘要：

Leistritz have developed an isothermal forging process for blades made of TiAl alloys during the past 18 years. The optimal process window was determined as 1100 degrees C to 1250 degrees C with extremely low strain rates. The high process temperature requires die material such as Molybdenum alloys under protective atmosphere. Leistritz have established the isothermal forging process on a special hydraulic press. First forged blades have been HPC blades of the Rolls-Royce BR715 engine made of Gamma-TAB. The following evolution step was the production of 900 blades for HPC 7-9 of the Rolls-Royce E3E experimental engine from TNB-V4. All machining of these blades was done in the Leistritz Nurnberg works. Up to now more than 10.000 LPT stage 3 blades for the PW 1100G for MTU have been forged of cast TNM. Currently Leistritz are the only approved supplier for these parts. (C) 2015 Published by Elsevier Ltd.
