Accelerated rejuvenation in metallic glasses subjected to elastostatic compression along alternating directions

Nikolai V. Priezjev

Summary: This study investigates the influence of static stress and alternating loading direction on the potential energy and mechanical properties of amorphous alloys using molecular dynamics simulations. It was found that at sufficiently large values of static stress, the binary glass becomes rejuvenated through collective, irreversible rearrangements of atoms. Including additional static stress orientation in the loading protocol amplifies the rejuvenation effect, leading to improvements in the mechanical properties of metallic glasses.

Cooling under Applied Stress Rejuvenates Amorphous Alloys and Enhances Their Ductility

Nikolai V. Priezjev

Summary: This study uses molecular dynamics simulations to investigate the effect of tensile stress applied during cooling of binary glasses on potential energy states and mechanical properties. The results show that higher applied stress can enhance potential energy and improve the plasticity of glasses. Additionally, the amorphous structure of rejuvenated glasses characterized by an increase in the number of contacts between smaller type atoms can enhance ductility in glasses prepared at larger applied stresses and higher initial temperatures.

Biocompatibility of platinum-based bulk metallic glass in orthopedic applications

Summary: The research suggests that nanopatterned Pt-BMGs have the potential to serve as an alternative to conventional metallic implants with simultaneous induction of osteoblasts and inhibition of osteoclasts. In vivo studies comparing Pt-BMG and titanium showed similar biocompatibility, indicating that further processing at the nanoscale could improve outcomes.

Accessing a broader range of energy states in metallic glasses by variable-amplitude oscillatory shear

Nikolai V. Priezjev

Summary: The research revealed that the potential energy and mechanical properties of amorphous materials can be influenced by variable-amplitude loading. Proper loading can rejuvenate well-annealed glasses, while improper loading can lead to a gradual decrease in energy states of poorly annealed glasses.

The role of annealing in determining the yielding behavior of glasses under cyclic shear deformation

Himangsu Bhaumik et al.

Summary: Recent computer simulations have shown that yielding behavior in amorphous solids is characterized by a discontinuous transition, with the degree of annealing playing a crucial role. Highly annealed glasses exhibit discontinuous stress changes at yielding, while poorly annealed glasses show gradual yielding. Additionally, in cyclic shear simulations, poorly annealed glasses tend to become better annealed as they approach the yielding point, with a modest discontinuous change at yielding.

Shear band healing in amorphous materials by small-amplitude oscillatory shear deformation

Nikolai V. Priezjev

Summary: This study investigates the effect of small-amplitude periodic shear on annealing of a shear band in binary glasses through molecular dynamics simulations. The results show that increasing strain amplitude leads to glasses being relocated to deeper potential energy levels, and mechanical tests demonstrate an increase in shear modulus and yield stress with loading at strain amplitudes close to the yield strain.

Decelerated aging in metallic glasses by low temperature thermal cycling

Marian Bruns et al.

Summary: Differential scanning calorimetry measurements on various bulk metallic glasses show no measurable rejuvenation during cryogenic thermal cycling, regardless of whether they are as-quenched or well-annealed samples. Molecular dynamics simulations of a generic glass former support these findings, indicating that aging is slowed down but not halted or reversed during thermal cycling, with the energy distribution continuing to narrow at a reduced rate.

Enhancing ductility in bulk metallic glasses by straining during cooling

Rodrigo Miguel Ojeda Mota et al.

Summary: The research reveals that straining a bulk metallic glass during cooling from the supercooled region can enhance its bending ductility, as the structure is pulled up the potential energy landscape. This method of cooling the excited liquid can improve the ductility of bulk metallic glasses.
