摘要
以TC4钛合金薄腹高筋构件零件为研究对象,通过对材料成形特性以及零件结构的分析,研究了锻件的成形方式及金属流动的特点,基于DEFORM-3D软件对锻件等温成形过程进行了数值模拟,并根据模拟结果进行了工艺优化,制定了最终的等温成形工艺方案,最后进行了等温锻造试验。研究结果表明:通过数值模拟及优化后的成形工艺方案可以成形出符合形状尺寸及性能要求的钛合金锻件。
Taking TC4 alloy component with thin web and high rib as the research object, the forming mode and the metal flow characteristics of the forgings are studied through the analysis of the material forming characteristics and the part structure. The isothermal forming process was simulated based on DEFORM-3D software. According to the simulation results, the process was optimized, the final isothermal forming process was developed, and the isothermal forging test was carried out. The results show that the numerical simulation and optimization of the forming process can form a titanium alloy component which meets the shape and performance requirements.
