Characteristics of primary recrystallization and its role in the sintering of metal powders

Process Induced Disorder in Crystalline Materials:Differentiating Defective Crystals from the Amorphous Form of Griseofulvin

“…Rearrangement of defects toward a configuration closer to that of the original crystal would be exothermic and could take place below the glass transition temperature, as is the case shown in Figure 5. This type of defect rearrangement is well established in cold worked metals and has been extensively investigated in metallurgical research 33–35. However, to the best of our knowledge, this kind of material behavior has not been reported for organic molecular crystals.…”

Modelling of Recrystallization Curves of Porous Copper-Titanium Powder Materials

“…Increasing of pores' quantity imposes extra free energy to sample at the expense of developed free surfaces as boundaries of pores [2,4]. The nucleation places of dynamical recrystallization centres are areas with highest concentration of crystalline structure defects like boundaries of pores during deformation [3].…”

“…A structure formation process during deforming of porous powder materials at the elevated temperatures has identical mechanisms with compact materials. At the same time, experimental investigations have shown that presence of additional pores' phase makes a substantial influence to kinetics of the process [1][2][3]. It is well-known [1], that mechanism, kinetics of structure formation and grain size are substantially and in a different way dependent from temperature, degree of deformation and strain rate.…”
