锻造温度对Ti60钛合金大规格棒材组织及性能的影响

Effect of Cold Forging on Microstructure of Ti60 Titanium Alloy Large Size Bar

研究了锻造温度对Ti60合金Φ350mm规格棒材组织、力学性能及探伤的影响。试验选用相同的试验坯料,按照变形方式、变形量相同而变形温度不同进行Ti60合金棒材α＋β两相区锻造。研究表明：Ti60合金棒材采用Tβ-40℃进行α＋β两相区锻造,其组织晶粒细小,且力学性能及探伤水平均优于采用Tβ-20℃进行α＋β两相区锻造的棒材。

The effect of temperature on the Ti60 alloy forging Φ350mm specifications bars, mechanical properties and flaw detection. Two sets of test blanks from the same bar, under the same deformation scale and deformation mode,use Tβ-40 ℃ and Tβ-20 ℃ to α＋β phases forge. Studies show that： Tβ-40 ℃ be phases forged Ti60 alloy bar, its organizational fine grain size and mechanical properties and testing levels is superior than the Tβ-20 ℃ be phases forged bar.
