Effects of thermohydrogen treatment on microstructures of α+β and β titanium alloy as-cast
The effects of thermohydrogen treatment on the microstructures of TC21 and Ti40 alloys as-cast were researched.The results show that the β phase content increases after charged hydrogen.Compound TixHy appears if H content reaches a certain content,which perfectly gathers on the grain-boundaries and/or dislocations and then diffuses into the grains.The microstructure of TC21 alloy after thermohydrogen treatment becomes fine and the best H content is 0.4％ (mass fraction).However,the influence of thermohydrogen treatment on Ti40 microstructure is not obvious.
