Additive manufacturing is a process of producing parts, involving incremental addition of material onto a flat or axial substrate. This manufacturing option is also called ‘growth’ because the product is formed by continuously building up layers of material until it is complete. Additive materials and techniques are modern and relevant. Employing these techniques, materials can be produced with various types of energy to fuse powders. The structurization mechanism is virtually unknown in this case. Using additive manufacturing techniques, samples were prepared from the VT1-0 alloy powder on a VT20 alloy substrate and from the VT20 alloy powder on a VT1-0 alloy substrate. The structures of samples cut out from different areas of the deposited material were studied and their microhardness was measured. The relationship between the structure and microhardness in the deposited material was shown. A structurization mechanism for titanium material through the deposition of titanium powder was proposed. A mechanism for the formation of pores in the metal was suggested. The structurization process was characterized by the redistribution of doping elements in the deposited metal and the substrate, as evidenced by changes in microhardness. The microhardness varied from the level characteristic of the substrate metal to the microhardness inherent in the deposited metal. The temperature gradient during the growth of a metal sample was uneven. This led to changes in the size of the structural components in the metal. The powder was fused layer by layer, with the formation of pores depending on the powder particle size. Larger particles formed larger pores compared to those formed by finer powders. The processes established in the experiments were consistent for both deposition options. The difference resided in the base metal, specifically its chemical composition. The proposed mechanism enhanced the general understanding of the structurization processes during additive growth (deposition) of titanium alloys from their powders.

增材制造是一种生产零件的过程，涉及将材料增量添加到平面或轴向基材上。这种制造选项也称为“增长”，因为产品是通过不断构建材料层直至完成而形成的。添加剂材料和技术是现代且相关的。利用这些技术，可以使用各种类型的能量来熔融粉末来生产材料。在这种情况下，结构化机制实际上是未知的。使用增材制造技术，在 VT20 合金基材上使用 VT1-0 合金粉末，在 VT1-0 合金基材上使用 VT20 合金粉末制备样品。研究了从沉积材料的不同区域切下的样品的结构并测量了它们的显微硬度。显示了沉积材料中的结构和显微硬度之间的关系。提出了通过沉积钛粉来实现钛材料的结构化机理。提出了金属中形成孔的机制。结构化过程的特点是沉积金属和基材中掺杂元素的重新分布，这可以通过显微硬度的变化来证明。显微硬度从基体金属的水平特性到沉积金属固有的显微硬度而变化。金属样品生长过程中的温度梯度不均匀。这导致金属结构部件的尺寸发生变化。粉末逐层熔融，根据粉末颗粒的大小形成孔隙。与较细粉末形成的孔相比，较大颗粒形成较大孔。实验中建立的工艺对于两种沉积选项都是一致的。差异在于贱金属，特别是其化学成分。所提出的机制增强了对钛合金粉末增材生长（沉积）过程中结构化过程的一般理解。
