Ti-6Al-4V经β-热处理后转变的β板状组织的粗糙度对其性能有很大影响。系统地研究了冷却速度对空气中拉伸和循环变形性能的影响。这些性能与冷却速率和控制微观结构特征相关。对于较薄的截面尺寸，空冷与水淬相比，从β转变温度开始较慢的冷却速率可使抗拉强度降低约70 MPa。冷却速率也影响循环变形行为。(C)2002 Elsevier Science B. V.保留所有权利。
The coarseness of the transformed beta plate structure of beta-heat treated Ti-6Al-4V has a strong influence on its properties. A systematic study of the effects of cooling rate on tensile and cyclic deformation properties in air was performed. The properties are correlated to the cooling rates and the controlling microstructural features. The tensile strength can be reduced by about 70 MPa with the slower cooling rate from the beta transus temperature when comparing air cooling to water quenching for thinner section sizes. The cooling rate also affects the cyclic deformation behaviour. (C) 2002 Elsevier Science B.V. All rights reserved.
