Hot Deformation of AISI 4340 Steel From a Dynamic Material Modeling Perspective
Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.This study presents numerical simulations of hot deformed AISI 4340 steel using Deform 3D, conducted at temperatures of 1000°C–1150°C and strain rates of 3–12 s−1. Processing maps and constitutive modeling characterize deformation mechanisms and flow stress behavior. Dynamic recrystallization acts as the dominant softening mechanism.

Inclusions in steel coated electrodes welds of car body [PDF]
Transport Problems, 2007 The goal of this project (BK-284/RT1/2007) is to chose the proper method of car body welding. SMAW could be treated as the main method used in the transport industry. Properties of metal weld deposits depend on many conditions.
