“…are produced, but also some structural evolution on the worn surface can occur, [1][2][3][4][5] and this evolution, in turn, will affect the wear process. It was noticed in our previous work [6][7][8] that the high energy impact contact load would result in an obvious structural evolution on the worn surface, and the impact wear cracks could initiate in the new structure or the interface between the surface layer and plastic deformation zone.…”

The TiNiNb alloy exhibits a linear increase in wear with a number of impacts at the low impact energy density E im of 1.6 J/cm 2 . However, a change in the volume wear occurs on the wear curve when E im is increased to 2.42 J/cm 2 . In this case, when the number of impacts N is more than 3 9 10 5 cycles, the wear rate decreases from 5.8 9 10 À6 to 1.9 9 10 À6 mm 3 /cycle, which is only one-half of that under low E im (1.6 J/cm 2 ). It is significant for practical applications because impact energy increases while the wear rate decreases. X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses show that a large number of amorphous structures are produced on the sample surface at high E im , while no new crystalline phases appear. The abnormal wear behavior of the TiNiNb alloy can be attributed to the excellent wear behavior of amorphous structure and the consumption of impact energy during amorphous structure production.

“…Work hardening mechanisms, impact wear, abrasive wear and the alloying of austenitic manganese steel have been investigated by several researchers and results have shown that under repeated impact and abrasive wear it work hardens rapidly and displays remarkable toughness [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] . Several other works on its surface treatment have also proved that surface treatment increases its surface hardness and wear resistance [22][23][24][25] . However, the rate of work hardening depends primarily on the amount of carbon in solution in the austenite matrix and the presence of a fine dispersion of carbides.…”

Workhardening behaviour and microstructural analysis of failed austenitic manganese steel crusher jaws

This study focussed on the work hardening behaviour and microstructure of austenitic manganese steel relative to premature failure of crusher jaws. Samples of sound and failed crusher jaws were taken, the change with depth from the working surface to the sample core was measured and their microstructures observed. The study revealed a sharp hardness gradient in the failed crusher jaws, and presence of large carbides at both the austenite grain boundaries and in the austenite matrix. The failure of crusher jaws was attributed to brittle fracture as a result of precipitates of carbides from the inability of precipitated carbides to absorb shock during impact working. Finally, we conclude that the failure occurred as a result of inadequate quenching operations during the manufacturing process that resulted in the formation of carbide precipitates which embrittle the austenitic manganese steel, reduce its ability to withstand shock and create a non uniform plastic flow as it is work hardening.

“…While the fatigue life is sensitive to the roughness and residual stress, insufficient shot peening and over shot peening will not produce good fatigue performance. The effect of surface work hardening on wear behavior of Hadfield steel was investigated by Yan et al 9 They found that after shot peening treatment, the grain sizes in top surface layer were decreased to about 11.1-17.4 nm, and the maximum hardened layer reached 100 mm. The effect of shot peening treatment on duplex stainless steel S32205 was studied by Feng et al 10 They revealed that shot peening treatment-induced CRS layer in both ferrite and austenite of duplex stainless steel S32205 reached to 150 and 200 mm, respectively, and the domain sizes were refined.…”

To optimize the surface properties such as surface roughness, residual stress, and micro-hardness of Ti1023 titanium alloy, the effects of shot peening on Ti1023 alloy were investigated. Surface roughness, surface topography, residual stress, micro-hardness, and micro-structure were carried out at different shot-peening parameters. The results demonstrate that the increased peening intensity enhances the surface roughness, compressive residual stresses, and hardness in subsurface, which is mainly due to the plastic deformation in the near surface layer. Specimen 11 has a low surface roughness of R a = 1.91 mm, well-developed dimple topography, higher compressive residual stress layer depth of 143 mm, and higher hardened layer depth of 200 mm. The ceramic shots with a diameter of 1.08 mm and peening intensity of 0.18 mm A are the optimal shot-peening conditions.
