Resumo
The consolidation of a quartz powders in crystalline (ceramics) and amorphous (glass) states is detected during high-pressure torsion in Bridgman anvils. The consolidation is shown to depend on preceding crushing-induced fragmentation. The role of the surfaces that appear during crushing and cracking is discussed. The dissipative channels that compete with fracture are determined.
