What Are The Difficulties In Forging And Processing Of Titanium Alloys? This Article Will Tell You [forged Information]

What are the difficulties in forging and processing of titanium alloys? Titanium alloys are widely used in aerospace, healthcare, chemistry and other fields due to their high strength, low density, excellent corrosion resistance and good biocompatibility. However, forging and processing of titanium alloys is a technically difficult process that involves many challenges. Today, Shanghai forging manufacturers will take you through the difficulties in forging and processing of titanium alloys.

The main difficulty in titanium alloy forging treatment is its low thermal conductivity. Titanium alloy has very low thermal conductivity, only 1/7 of steel, 1/16 of aluminum and 1/25 of copper. This means that it is difficult to quickly transfer heat during forging, resulting in rapid accumulation of heat in the cutting area, causing tools and mold to withstand extremely high temperatures, accelerate wear and even failure. In addition, high temperatures can also damage the surface integrity of titanium alloy parts, thereby reducing geometric accuracy. In severe cases, work hardening may occur, which can damage its fatigue strength. Therefore, during the titanium alloy forging process, how to effectively control heat accumulation, maintain the life of tools and molds, and ensure the surface quality and accuracy of parts has become an urgent issue.

The relatively low elastic modulus of titanium alloys is also a major difficulty in forging and processing. Titanium alloys are prone to elastic deformation during forging, especially when dealing with thin-walled or annular parts, this problem is even more prominent. Because the plastic deformation ability of titanium alloy is very strong, when the workpiece material is subjected to external forces, local deformation may exceed the elastic range, resulting in plastic deformation. This plastic deformation will not only increase the cutting pressure and enhance the "elastic" rebound phenomenon of the workpiece, but will also further increase the friction between the tool and the workpiece, thereby reducing the reduction efficiency and tool life. Therefore, how to effectively control elastic deformation and maintain the shape and dimensional accuracy of the workpiece during titanium alloy forging has become another major challenge.

The adhesion and high vibration characteristics of titanium alloys also bring considerable difficulties to forging and processing. Titanium alloy has a strong affinity for the tool and is easily adhered to the tool during the cutting process, forming a continuous chip, interfering with the cutting process, and in severe cases, the tool may be damaged. In addition, the high vibration characteristics during titanium alloy processing are also a major unstable factor, which not only aggravates tool wear, but also seriously affects the accuracy of the treatment and surface quality.

To address these difficulties in titanium alloy forging treatment, the industry has explored some effective solutions. For example, use high-performance tool materials (such as carbides, ceramics, etc.) to improve the high temperature resistance and wear resistance of the tool; use coolant for complete cooling to reduce the temperature of the cutting area and reduce heat accumulation; optimize the forging process Parameters such as reducing cutting speed, increasing feed speed, etc., to reduce tool wear and improve processing efficiency; new processing methods, such as sonication technology, are adopted to reduce contact time between the tool and the workpiece and extend tool life.

During the forging and processing of titanium alloys, some details need to be paid attention to. For example, before forging, the chemical composition and microstructure of the titanium alloy raw materials should be strictly controlled to avoid defects such as inclusions and pores. During the forging process, the heating temperature and insulation time should be strictly controlled to avoid overheating or excessive combustion; after forging, it should be completed. Perform heat treatment in time to eliminate residual stress and improve the mechanical properties of the material.
