Analysis of bright spots in TC4 titanium alloy rods with low magnification organization

August 10, 2023

Titanium Alloy has the advantages of low density, high specific strength, etc. It is widely used in aerospace field.TC4 titanium alloy has excellent comprehensive performance and is the two-phase titanium alloy with large dosage.The types of titanium alloy products can be divided into plates, rods, wires, tubes and anomalous forgings, etc., in which the production of rods accounted for about one-fifth of all kinds of titanium processed materials.

TC4 titanium alloy bars can be used as engine shells, missiles, pressure vessels and other key components after subsequent processing, so the organization and properties of the material have very strict requirements. In the production process of titanium alloy bars, occasionally appear bright bars, bright spots and other low-fold organization abnormalities, the formation of most of these defects belongs to the composition of segregation type defects, commonly found in β-type titanium alloys with a large number of elemental species. According to the different parts of the segregation and the hardness of the matrix organization, segregation can be divided into hard segregation and soft segregation, such defects are difficult to be detected by flaw detection; however, the existence of this defect may affect the use of the material, and different standard requirements for such defects give different ways of treatment.

Titanium Bar manufacturers in the process of long-term production practice found in a batch of two batches of TC4 bar inspection process appeared in the bar low times the organization of the abnormal situation, but its morphology varies greatly; its research and analysis, and put forward the corresponding solution, with a view to the normal production of TC4 titanium alloy bar to provide .
