Influence of Thermohydrogen Treatment on Machinability of Ti600 Alloy

The influence of thermohydrogen treatment on machinability of Ti600 alloy has been studied by turning a group of Ti600 alloy testing workpieces with different hydrogen content, measuring cutting force and surface roughness as well as observing chip morphology. Results of this experiment reveal that machinability of Ti600 alloy improves with increasing hydrogen content, and there is an optimal range of hydrogen content, in excess of the range, with the hydrogen content increasing, machinability of Ti600 alloy is reduced.
