It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel.  This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...

Forging is a manufacturing process that consists of shaping the metal using localized compression forces. The blows are delivered with a hammer (often an electric hammer) or a die. In this paper, different methods of forging (multi-directional forging, hot forging, near-beta forging, multi-axial forging, direct powder forging, warm forging and ring forging) are discussed. The main problems that...

To obtain excellent mechanical properties from large cross-sections of plastic mould steel (SDP1), we conducted multi-directional forging (MDF) to control the microstructure ingots. investigate microstructural evolution SDP1 during MDF, performed hot at 1150 °C using a THP01–500A hydraulic press. The dimensions specimens were Φ38 mm × 80 mm. after was observed under metallographic microscope. F...
