Ti-6Al-4V合金是应用于航空和汽车工业领域的关键结构件,但是它硬度高,难加工,价格昂贵,且大尺寸毛坯时材料利用率很低,采用传统加工方法很难满足现代制造的需求。针对Ti-6Al-4V合金机翼,采用铅模拟实验优化了合理的锻坯形状,并引入了一种闭式等温锻造工艺,研究了等温锻造Ti-6Al-4V合金机翼的成形能力、机械性能和工艺参数等性能。结果表明:与传统加工的钛合金机翼相比,等温锻造机翼显著的改善了零件的机械性能,材料利用率从13%提高到50%;在950℃的等温锻造温度下,Ti-6Al-4V基体内片状α相逐渐转变为β相,而当锻造温度为900℃时,这种相变效果呈减弱趋势。
Ti-6Al-4V alloy is a key structural component used in aviation and automobile industry, but its hardness is high, difficult to process and expensive, and its material utilization rate is very low when it comes to large-size blank. It is difficult to meet the requirements of modern manufacturing by using traditional processing methods The demand. For the Ti-6Al-4V alloy wing, a lead simulation experiment was used to optimize the shape of the forging, and a closed isothermal forging process was introduced to study the forming ability of isothermal forged Ti-6Al-4V alloy wing. The mechanical Performance and process parameters and other performance. The results show that compared with the conventional titanium alloy wing, isothermal forging wing significantly improves the mechanical properties of the parts, the material utilization rate increased from 13% to 50%; at 950 ℃ isothermal forging temperature, Ti-6Al -4V matrix, the α phase gradually transformed into β phase, while the forging temperature was 900 ℃, the phase transformation effect showed a decreasing trend.
