The Effect of Multidirectional Forging on the Deformation and Microstructure of the Al–Mg Alloy

Physics of Metals and Metallography, 2020
The effect of multidirectional forging on the evolution of the grain structure and the parameters of secondary-phase particles in the aluminum–magnesium alloy (Russian grade 1565ch) has been investigated using scanning and transmission electron microscopy. The multidirectional forging was performed at 200, 350, and 500°C to a total strain of 12.

Multidirectional forging of magnesium matrix composites: Effect on microstructures and tensile properties

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2010
Abstract A particulate reinforced magnesium matrix composite fabricated by stir casting was subjected to multidirectional forging (MDF) at a temperature of 420 °C. The results showed that grains of matrix in the composite were significantly refined after 1 MDF pass, and gradually refined till 3 MDF passes.

Multidirectional forging of AZ91 magnesium alloy and its effects on microstructures and mechanical properties

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2015
Abstract AZ91 alloy was subjected to multidirectional forging (MDF) and the relationship between microstructures and mechanical properties generated by MDF were investigated. The results showed that after 1 MDF pass grain size of the alloy decreased compared with as-cast alloy, and the amount of recrystallization grains increased when the MDF ...

Effect of multidirectional forging on microstructures and tensile properties of a particulate reinforced magnesium matrix composite

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2011
Abstract A particulate reinforced magnesium matrix composite prepared with stir casting was subjected to multidirectional forging (MDF). The results showed that after 1 MDF pass the grain size of matrix in the composites decreased compared with as-cast composite, and increased with increasing the MDF temperature from 370 °C to 450 °C. With increasing

Microstructures and mechanical properties of SiCp/AZ91 magnesium matrix nanocomposites processed by multidirectional forging

Journal of Alloys and Compounds, 2015
Abstract A particulate reinforced magnesium matrix nanocomposite was subjected to multidirectional forging (MDF). The results showed that the microstructure of the nanocomposite mainly consisted of some large initial grains and fine recrystallized grains along initial grain boundaries after 1 MDF pass.

Investigation of the required clamping force at multidirectional undercut-forging

Production Engineering, 2018
A hot forging process allows to produce parts of excellent quality and technical properties. Nevertheless, it is not possible to forge undercut geometries like piston pin bores, it is usually necessary to manufacture them in subsequent processes. Thus, an undercut-forging process was newly developed.

Effect of Warm Multidirectional Forging on the Microstructure and Mechanical Properties of a High-Nitrogen Austenitic Steel

Russian Physics Journal, 2023
The features of the microstructure of the high-nitrogen austenitic VNS-53-Sh steel after multidirectional isothermal forging have been studied by transmission electron microscopy. The formation of an inhomogeneous deformed microstructure is shown. Regions of significant fragmentation are observed, in which the grain-subgrain structure is refined. Areas
