美国芝加哥ITT研究所在60年代中期发展的等温锻造技术,越来越受到人们的关注。Thyssen Schmiedtechnik所作的试验表明,在等温条件下,钛合金在锻造过程中流动性有相当大的提高。采用等温精密锻造技术,可以节省40％的材料,降低成本20％左右。概述在等温锻造中,锻模和锻件的温度相同。在大多数情况下,锻模采用感应加热。等温锻造的工艺条件允许在很低的变形速度(如10~(-3)～10~(-2)秒~(-1))下工作和保持较小的屈服应力。由于等温锻造中锻件温度最均匀 The ITT Institute of Chicago in the United States in the mid-60s developed isothermal forging technology, more and more people’s attention. Tests by Thyssen Schmiedtechnik show that there is a considerable increase in flowability of the titanium alloy during forging under isothermal conditions. The use of isothermal precision forging technology, can save 40% of the material, reduce the cost of about 20%. Overview In isothermal forging, forging dies and forgings have the same temperature. In most cases, die is induction heated. Isothermal forging process conditions allow low deformation speed (such as 10 ~ (-3) ~ 10 ~ (-2) s -1) work and maintain a smaller yield stress. As forging temperature isothermal forging the most uniform
