Effect of Aging Treatment on Microstructure and Mechanical Properties of Near Beta Type Titanium Alloy TLM AITranslate
Abstract AITranslate
The effects were investigated of different aging temperatures and holding time on the microstructure and mechanical properties of near beta type titanium alloy TLM.The results show that the characteristics of alloy microstructure after beta single phase solid solution and aging treatment are as follows：αphase precipitates out on both sides of the grain boundary along a certain crystal orientation in colony form,and there is also a large amount of precipitatedαphase inside the crystal grains.With the increase of aging temperature,the size of precipitatedαphase is gradually increasing and tends to be uniform,alloy strength is decreasing and ductility is increasing.When aging temperature rises from 480 ℃ to 510 ℃,the strengthening effect is the most obvious,and the increment of tensile strength reaches the maximum value of 184 MPa.When the temperature rises from 510 ℃ to 540 ℃,the increment of tensile strength reaches the minimum value equal to 63 MPa.With the increase of aging time,the size is obviously enlarged of precipitatedαphase along the grain boundary in colony form,there is also someαphase appearing in the precipitation-free zone,and its distribution gradually tends to be uniform.Aged at 480℃,alloy strength increases and ductility decreases with the increase of holding time.Aged at 510 ℃,alloy strength and ductility have no obvious change with the increase of holding time.Aged at 540 ℃,alloy strength is decreasing and ductility is increasing with the increase of holding time.
