高Nb--TiAl合金叶片锻造模拟
Forging simulation of blades of a high niobium containing TiAl based alloy
摘要
Abstract
The isothermal forging process of blades of a β-γ high niobium containing TiAl based alloy was simulated by using a Deform-3D software, with focus on the analysis of the effective strain, effective stress and temperature distributions. The results dem-onstrate that the effective strains of the blade body and rabbet uniformly distribute during the isothermal forging process. With the in-crease of top die speed and preheating temperature, the effective stress decreases and the dynamic recrystallization is easy to take place . The preheating temperature of 1250-1300℃ and the top die speed of 1. 0-1. 5 mm·s-1 help to improve the quality of the forged blades.关键词
