在耗散结构理论和材料动态行为模拟方法(DMM)的基础上,作者提出了一种确定锻造热力参数范围的方法,以获得组织和性能稳定一致的钛合金锻件。本文中以 TC11合金为例详细说明了应用所提出的方法确定锻造热力参数范围的过程,并首次提供对研究 TC11合金锤上和压力机上锻造过程有实用价值的曲线。根据试验研究结果,对于 TC11合金,在β/(α+β)相变点附近(但不超过相变点)采用大变形程度一次成形,有利于获得组织和性能稳定一致的锻件,而且对所用设备的要求比较宽松。
Based on the dissipative structure theory and the method of simulating the dynamic behavior of materials (DMM), the authors propose a method to determine the range of forging thermal parameters in order to obtain a stable and uniform titanium alloy forging. In this paper, the TC11 alloy is taken as an example to illustrate the application of the proposed method to determine the range of forging thermal parameters, and for the first time provides a useful curve to study the forging process on TC11 alloy hammers and presses. According to the experimental results, for the TC11 alloy, a large deformation degree is formed in the vicinity of the β / (α + β) transformation point (but not exceeding the transformation point), which is favorable for obtaining a forging having stable structure and consistent performance. Equipment requirements more relaxed.
