Technological basis of SHS extrusion

Microstructure and mechanical properties of Ni3Al fabricated by thermal explosion and hot extrusion

“…The hot extrusion could solve the trouble, but it resulted in the crystal coarsening. The studies of Merzhanov and Podlesov [18,19] showed that the combustion synthesis and hot extrusion technology could not only well densify the alloy, but also avoid the crystal coarsening. Furthermore, Morsi and Minay [20][21][22] had found that the combustion synthesis and hot extrusion could well improve the microstructure and mechanical properties of Ni 3 Al.…”

Peculiarities of the production of elongated items from a ceramic material with nanoscale structure by the SHS extrusion method

“…The dependence of the extrusion effi ciency K m of the extruded part of the material (the mass ratio between the extruded part and the initial raw material) on the delay time is shown in Fig. 3 [8].…”

Model of nonstationary propagation of a solid-state chemical transformation under uniaxial loading

“…For instance, mechanical stresses which occur in solids during transformations can impact chemical reaction rate directly or indirectly [2]. This fact, in particular, is used in material synthesis under loading [3,4] or in implementing special initiation conditions [5,6]. Imposed load can determine the conditions of the process,accelerate or decelerate the reaction, and change the kinetics of concurrent processes of structure formation.…”

“…In the literature, there are some reports on modeling condensed-phase reactions under compression [3,7,8] or quasistatic loading [9,10], but purposeful theoretical investigations of the impact of loading conditions on solid-state transformations have not been performed.…”
