Abstract

Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis are used to study the structure, phase composition, and deformation behavior of a titanium Ti–10V–2Fe–3Al alloy with different carbon contents. It is shown that as the carbon content in the alloy increases to the maximum carbon solubility, the dispersity of the secondary α-phase increases and, therefore, the strength of the alloy increases. After reaching the carbon solubility limit, titanium carbide particles are observed in the alloy structure; the morphology of the particles and their sizes are similar to those of the primary α-phase. The titanium carbide particles do not affect the strength and plasticity characteristics of the alloy during tensile tests and retain their initial shape after deformation. At the stage of strain localization, titanium carbide particles are sites of micropore nucleation.

碳对Ti–10V–2Fe–3Al合金的变形行为和组织的影响的研究

摘要

扫描电子显微镜（SEM）和X射线衍射（XRD）分析用于研究具有不同碳含量的钛Ti-10V-2Fe-3Al合金的结构，相组成和变形行为。可以看出，随着合金中碳含量增加到最大碳溶解度，第二α相的分散性增加，因此合金的强度增加。达到碳溶解度极限后，在合金结构中观察到碳化钛颗粒。颗粒的形态和大小与初生α相相似。碳化钛颗粒在拉伸试验期间不会影响合金的强度和可塑性，并且在变形后仍保持其初始形状。在应变定位阶段
