Dynamics of serrated flow in a bulk metallic glass [PDF]
AIP Advances, 2011 Under compression loading, bulk metallic glasses (BMGs) irreversibly deform through shear banding manifested as a serrated flow behavior. By using a statistical analysis together with a complementary dynamical analysis of the stress-time curves during ...

Effect of Auto-Tuning on Serrated Flow Behavior
Metals, 2019 The mechanical response of a servo-hydraulic testing system is affected by the stiffness of test specimens. An adaptive controller helps in auto-tuning the system by setting the optimal proportional-integral-derivative values for the subsequent test as ...

Critical serrated flow features during nanoindentation in La-based bulk metallic glasses [PDF]
, 2007 La57.6Al17.5(Cu,Ni)(24.9) and La64Al14(Cu,Ni)(22) bulk metallic glasses (BMGs) were prepared by copper-mould casting method. Plastic deformation behavior of the two BMGs at various loading rates was studied by nanoindentation. The results showed that the

On the normal and inverse Portevin–Le Chatelier behavior in hot rolled Inconel 617 superalloy
Journal of Materials Research and Technology, 2023 In the present study the effect of hot rolling process on the normal and inverse Portevin-Le Chatelier behavior was investigated. The hot rolling process was carried out at 950 °C, 1050 °C, and 1150 °C to capture the effect of thermomechanical process on
