The titanium alloy material has a tendency to fill the grinding wheel, which brings difficulties to the grinding of titanium alloy rods and TC4 titanium alloys.When grinding, the higher temperature rise generated at the interface between the metal and the grinding wheel causes the grinding surface to produce Higher residual stress, and at the same […]
Titanium is a metallic element, gray, atomic number 22, relative atomic mass 47.867. It can burn in nitrogen with high melting point. Blunt titanium and titanium-based alloys are new structural materials, mainly used in the aerospace industry and the marine industry. Because titanium alloy materials have high melting point, small specific gravity, high specific strength, […]
In the actual manufacturing process of titanium rods, for the physical surface polishing of TC4 titanium alloy and TC11 titanium alloy rods, the following mainly introduces the commonly used surface polishing methods of TC4 titanium rods and titanium alloy rods. Fine grinding That is, the surface of titanium and titanium alloy castings is ground by […]
Titanium is a very corrosion-resistant metal. The thermodynamic data of titanium indicate that titanium is a thermodynamically unstable metal. If titanium can dissolve to form Ti2 +, its standard electrode potential is very negative (-1.63V), and its surface is always covered with a passive oxide film. This steadily shifts the stable potential of titanium to […]
The existence of defects in titanium forgings may affect the processing quality or processing quality of subsequent processes, and some will seriously affect the performance and use of forgings, and even greatly reduce the service life of the manufactured parts, endangering safety. Therefore, in order to ensure or improve the quality of forgings, in addition […]
1. Difficulties in grinding and polishing titanium alloys The preparation of metallographic samples of titanium and titanium alloys is more difficult than steel, and their polishing and polishing efficiency is low. Excessive cutting and polishing processes will produce deformation twins in the α phase. After the deformation twins are generated, the microstructure of titanium The […]
Titanium alloy has been widely used in aerospace, shipbuilding, machinery, chemical industry and other fields due to its excellent characteristics such as light weight, high specific strength, and good corrosion resistance. However, its low surface hardness, poor wear resistance, and unsatisfactory corrosion resistance make it difficult for titanium alloys to meet the requirements of practical […]
Titanium alloy has a small specific gravity (about 4.5), a high melting point (about 1600 ° C), good plasticity, high specific strength, strong corrosion resistance, and long-term work at high temperatures (currently hot-strength titanium alloy has been used at 500 ° C). Therefore, it has been increasingly used as an important bearing component of aircraft […]
1. Metallurgical quality of raw materials Most of the defects of titanium alloy forgings exist in the raw materials. Considering the actual situation of China’s titanium industry production (raw materials, processes, etc.), coupled with the expensive and difficult processing of titanium alloys, the shape of forgings is usually more complicated, which makes certain difficulties in […]
The TC4 titanium alloy, Ti-6Al-4V, is the earliest and most widely developed titanium alloy in the world. Its output accounts for more than half of the total output of various titanium alloy semi-finished products in the world, and more than 80% in the aerospace industry. Al increases the room temperature strength and thermal strength properties […]
