hypotype
plesiotype

Near b - titanium ti - 1023 alloy of high - strength , good fatigue strength and excellent hardenability has both a relatively low 3 - transus temperature ( 798c ) and a low forging temperature range , which make it suitable for superplastic isothermal forging to manufacture complex forge pieces
Ti - 1023合金属于近型钛合金，具有高强、高韧、高淬透性等特点，而且它的相变温度( 800左右)和锻造温度均较低，非常适合于采用超塑性等温模锻方法制造复杂锻件。
