摘要/Abstract

摘要： 随着钛合金装备在航空、航天、航海等领域的使用逐渐增多，其服役环境日益严苛，对构件材料的抗腐蚀性能及室温应力蠕变性能提出了更高要求。针对钛合金耐蚀性及抗压缩蠕变的性能，分析了激光增材制造TC4合金不同热处理状态试样电化学及室温压缩蠕变性能，并结合蠕变曲线修正了蠕变第Ⅰ阶段本构方程的参数。结果表明，双重退火处理会显著减小增材制造TC4钛合金中α板条长径比与尺寸，而固溶时效可使α板条长径比增大、尺寸减小，导致了材料耐蚀性、屈服极限以及抗压缩蠕变性能的变化。沉积态合金经过固溶时效后自腐蚀电流降低64.92%，稳态蠕变应变率降低46.31%，蠕变应变降低50%。而经过双重退火后合金自腐蚀电流降低26.14%，稳态蠕变应变率提升111.20%，蠕变应变提升48.68%。相比于铸锻工艺制备TC4合金蠕变本构方程，修正后的拟合系数与蠕变曲线吻合度更高。

Abstract: The increasing adoption of titanium alloy equipment in aviation, aerospace, navigation and other harsh service environments requires higher corrosion resistance and better room temperature stress creep performance of component materials. This study investigates the effect of heat treatment on the corrosion resistance and room temperature compressive creep properties of Laser based Additive Manufactured (LAM) TC4 alloy, and modify the parameters of the constitutive equation in the deceleration creep stage with the creep curve. The experimental results demonstrate that the aspect ratio of the α-lamellae markedly decreases after double stage annealing, while slightly increases with solution aging; the size of the α-lamellae slightly decreases after double stage annealing, while markedly increases with solution aging, leading to changes of the material in corrosion resistance, yield strength and critical stress. The corrosion current, the steady-state creep strain rate and the creep strain decrease by 64.92%, 46.31% and 50% respectively after solution aging of the as-deposited state. The corrosion current decreases by 26.14%, and the steady-state creep strain rate and the creep strain increase by 111.20% and 48.68% respectively after double annealing. Compared with the constitutive equation of TC4 alloy prepared by casting and forging process, the modified fitting coefficient demonstrates a higher consistency with the creep curve.

Key words: laser based additive manufacturing, TC4 alloy, corrosion resistance, room temperature compression creep, creep constitutive equation
