Titanium alloy processing characteristics and types

With the wide application of titanium alloy processing, more and more people are beginning to realize the importance of titanium alloy processing. The editor often receives inquiries from customers. Today, I will make a summary of titanium alloy processing problems for everyone!



　　 1. Types of titanium alloys

　　 From the metal structure, titanium alloys can be divided into α titanium alloys, β titanium alloys, and α + β titanium alloys;

　　 High strength at a temperature of ~600℃, stable structure, strong oxidation resistance and creep resistance. Its main brands are TA4~TA8, etc.;

　　 β titanium alloy; this type of titanium alloy has good cold deformation and plasticity. Through quenching and aging treatment, the alloy can obtain high room temperature strength and is suitable for use below 350°C. Its main brands are TB1, TB2, TB3, etc.;

　　α+β titanium alloy gold; this kind of titanium alloy has good high-temperature deformation properties, good toughness and plasticity, can be quenched and strengthened, and has high high-temperature strength. It can work for a long time at 400℃. Its grades mainly include TC1~TC6, TC9, TC11, etc.

　　 2. Processing characteristics of titanium alloy

　　Titanium alloy is a difficult material to process, and its main processing characteristics are as follows;

　　A, heavy cutting edge load

　　 is mainly because the cutting deformation coefficient is small when processing titanium alloy, and the cutting force is concentrated near the cutting edge, which is easy to cause chipping.

　　 B, high cutting temperature

　　Titanium alloy has poor thermal conductivity, and the temperature in the cutting area is about twice as high as that of 45 steel.

　　 C, severe tool wear

　　 Titanium is relatively active and easily reacts with oxygen and nitrogen to form a hard and brittle expression, which intensifies tool wear.

　　D, flank surface friction is large
