Autor: Tong Daming, Zhang Ziyang, Li Zhuguo, Gu Jianfeng, Li Sijia, Zhang Qunli, Li Chuanwei, Zhao Junyu, Hu Zhaonan

Publikováno v: Heat Treatment and Surface Engineering, Vol 4, Iss 1, Pp 20-34 (2022)

In this study, a thermal–phase–mechanical coupled numerical model was presented for the prediction of the distribution of temperature, phase and residual stress of 42CrMo steel during two-track laser hardening process. Austenite and tempering tra

HCF Failure Modes and Mechanisms of Dissimilar Welds of Martensite/Austenite Metals at Elevated Temperature

Autor: Shao Chendong, Cui Haichao, Lu Fenggui, Li Zhuguo

Publikováno v: MATEC Web of Conferences, Vol 269, p 03004 (2019)

In this paper, the high cycle fatigue (HCF) behavior and failure mechanism of welded joint for martensite/austenite dissimilar metals were systematically investigated at elevated temperature. The HCF tests were performed at different elevated tempera
