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

The Effect of Multidirectional Forging on the Deformation and Microstructure of the Al–Mg Alloy
Physics of Metals and Metallography, 2020The 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.

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.
