Effect of Heat Treatment Temperature on Microstructure of Ti-42.5Al-4Nb-1Mo-0.2B Alloy for Internal Combustion Engine AITranslate
Abstract AITranslate
The effect was studied of heat treatment temperature on microstructure of Ti-42.5Al-4Nb-1Mo-0.2 Balloy for internal combustion engine.The results show that the alloy has nearly lamellar microstructure in the as-cast state,mainly composed of fine lamellar clusters and B2 phase andγphase around the lamellar clusters.The quenched alloys at 1200℃ and 1250℃ have similar microstructure.With the quenching temperature is increased to 1300℃,γphase in quenched microstructure disappears,and there are some long rod-shaped fine α2 grains in B2 grains.After heat treatment at 1200℃ and cooling to room temperature, the alloy has the microstructure of α2/γ lamellar clusters,B2 phase andγphase.When the heat treatment temperature is up to 1250℃,the number ofαgrains and α2/γ lamellar clusters begins to increase, and their size also gradually increases.When the heat treatment temperature rises to 1300℃,the alloy has nearly lamellar fine α+β microstructure.
