Cyclic deformation and dynamic compressive properties of copper bicrystals

Microstructural evolution associated with shear location of AISI 52100 under high strain rate loading

“…The grain refinement is a typical characteristic in the shear localization bands [18][19][20][21][22][23][24][25][26][27][28][29][30]. The grain size was gradually reduced to a sub-micro and nanometer scale.…”

“…Extensive work has been conducted on ASBs in a wide range of materials such as titanium alloys, austenitic stainless steel, pure niobium, aluminum alloys, magnesium alloy, copper bicrystals, TC16 alloy et al [23][24][25][26][27][28][29][30]. Mostly, these materials have good ductility.…”

Mechanical properties and fracture behaviors on 6061 aluminum alloy under shear stress state

“…Several kinds of shear specimens were used to investigate the mechanical behaviors of materials by many scholars [6][7][8]. These specimens were loaded through compression loading and suited for the moderate thick-walled flat, but are not suited for the thin-walled flat.…”

The strain amplitude controlled fatigue behavior of pure copper with ultra large grain size

“…The copper normal dislocation evolution and microstructure characteristics in fatigued have been systematic investigated in the past decade [1][2][3][4][5][6][7][8]. It is well known that the dislocation development in low cycle fatigue for copper is a sequence of loop patches, a vein structure, persistent slip bands (PSBs), walls, cells and mis-oriented cells [9][10][11][12][13].…”
