Effect of Welding Heat Input on Microstructure and Impact Toughness in the Simulated CGHAZ of Low Carbon Mo-V-Ti-N-B Steel
Autor: Mingliang Qiao, Huibing Fan, Genhao Shi, Leping Wang, Qiuming Wang, Qingfeng Wang, Riping Liu
Publikováno v: Metals, Vol 11, Iss 12, p 1997 (2021)
Welding thermal cycles with heat inputs ranging from 25 to 75 kJ/cm were performed on a Gleeble 3500. The impact energy improved significantly (from 10 to 112 J), whereas the simulated coarse-grain heat-affected zone (CGHAZ) microstructure changed fr
