The association of twinning and fracture in bcc metals

The low-temperature mechanical behavior of molybdenum-rhenium

“…This study addresses a longstanding question regarding the connections between twinning and fracture. 17 Interestingly, the fi ndings of a seminal study of Mo-51 wt.% Re have played an important role in the ongoing debate. 18 Moly-rhenium alloys are also prized for their improved formability; therefore, the crystallographic texture and anisotropy of the sheet material were investigated in both the cold-rolled and recrystallized conditions.…”

Twinning-dominated nucleation, propagation and deflection of crack in molybdenum characterized within situtransmission electron microscopy

“…Meanwhile, deformation twinning can also be activated near or away from cracks under the same conditions. Many studies have been devoted to correlate the links between twins and cracks [1,2]. The crack tip is a probable nucleation site for deformation twins owing to high local stress, especially at high strain rates and low temperatures [3][4][5].…”

Controlled shock loading conditions for micrstructural correlation of dynamic damage behavior

“…Dynamic material damage develops through an evolution of microstructural changes from the atomic scale to the macroscale damage event and is affected significantly by defects such as grain boundaries and inclusions within structural metals that typically serve as failure initiation sites. for some defect types, their mere presence is enough to cause failure, for others, spatial considerations such as distribution or density can be critical [1]. Shock compression via plate impact is used to investigate dynamic damage processes because of the ability to control global onedimensional, planar strain loading conditions and to recover the sample for metallurgical analysis.…”
