Ductility of chromium steels 15Kh13N2, 10Kh13N3MFB, and 10Kh17N13M2T is studied as a function of the stress-strain state and deformation temperature using fracture phenomenological theory. Computer simulation of the process of pipe extrusion is performed using QForm software. A dependence is proposed describing the ductility diagram, and empirical coefficients are determined by tests in a Gleeble 3800 unit.

管材挤压过程中铬钢延展性的研究

使用断裂现象学理论，研究了铬钢 15Kh13N2、10Kh13N3MFB 和 10Kh17N13M2T 的延展性与应力应变状态和变形温度的关系。使用 QForm 软件对管材挤出过程进行计算机模拟。提出了描述延展性图的相关性，并且经验系数通过在 Gleeble 3800 单元中的测试确定。
