摘要

热成形马氏体铬钢是现有压硬化钢22MnB5的可能替代品。通过适当的热处理,马氏体铬钢的强度和延展性都可以达到很高的值。因此,采用热成形马氏体铬钢可以生产出具有高碰撞安全性的汽车车身零部件。为了确定板材的可成形性,成形极限曲线是目前最先进的。传统的成形极限曲线是在室温下记录的,并不能充分描述热板料成形的成形能力,因为它强烈地依赖于温度。因此,本文根据马氏体铬钢AISI 420C (X46Cr13)的工艺路线,采用实验-数值方法确定高成形温度下的准等温FLC。结果表明:随着成形温度的升高,成形性能有所提高,在1050℃时成形性能最高;

Hot forming limit curves for numerical press hardening simulation of AISI 420C
A possible alternative to the established press hardening steel 22MnB5 are hot formed martensitic chromium steels. Both strength and ductility of the martensitic chromium steels can reach very high values with appropriate heat treatments. Therefore, car body parts with high crash safety can be produced by hot forming martensitic chromium steels. To identify the formability of a sheet metal, forming limit curves are state of the art. Conventional forming limit curves are recorded at room temperature and do not adequately describe the forming capacity for hot sheet metal forming as it strongly depends on temperature. Therefore, in this paper, an experimental-numerical method for determining quasi-isothermal FLC at high forming temperatures is applied to the martensitic chromium steel AISI 420C (X46Cr13) for forming temperatures between 7501,050 °C according to its process route. The results show an increase of the formability with rising forming temperature with the highest at 1,050 °C.
