Overview of the Titanium Alloy Industry

Titanium alloys have excellent performance, but the processing is very difficult in engineering. When the hardness is less than HB 300, there is severe cutter adhering; When the temperature is greater than 370 degrees Celsius, it is difficult to machine due to the hardness, and most titanium alloys have low thermal conductivity. The heat generated during the machining process will not be quickly transferred to the workpiece but will accumulate in the cutting area. It will cause rapid tool wear, and also it will damage the surface integrity of the part, leading to a decrease in geometric accuracy of the part and the occurrence of work hardening phenomenon.

Especially for specific models of military titanium materials, multiple plastic processing is generally required. Ensuring uniform and stable quality and achieving industrial mass production is a technical challenge worldwide.

Currently, only five countries in the world, including the United States, Russia, Japan, China, and the former Commonwealth of Independent States (Ukraine and Kazakhstan), have fully titanium material processing and manufacturing processes in the world, presenting a situation of five strong competition for dominance.

Refer to classification, titanium alloys can mainly be divided into α industrial pure titanium, titanium alloy Β titanium alloys, and α+β titanium alloys, which are widely used in industries such as aviation, chemical, and metallurgy, as they are made into different structures for different purposes.
