等温模 meaning in English

isothermal dies

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。
In this paper , 130mm diameter hot - rolled bars ( 3 transus temperature is 798 c ) were used in experiments . the superplastic property of ti - 1023 alloy was studied systematically by the experiments of tensile and compression . the preparation method of fine - crystalline structure and the processing parameters of superplastic forging are optimized
本文以130mm热轧棒材为原材料，通过超塑性拉伸和超塑性压缩试验，对ti - 1023合金的超塑性进行系统研究，研究坯料细晶组织制备方法，优化超塑成形工艺参数，为高筋薄腹板复杂形状ti - 1023合金锻件超塑性等温模锻工艺的制定提供试验依据。
