Introduction
I am Sreenivas, a Ph.D. candidate at Johns Hopkins University. Under the guidance of Prof. Tim Weihs, I develop magnesium alloys for structural and biomedical applications. My research explores mechanical properties, corrosion resistance, and degradation kinetics for implant materials. I collaborate with NIST and PNNL and use APT and FIB to study solute clustering. I am passionate about metallurgy, biomaterials, and mentorship.

Micron-scale metal-based composite powders are promising for energetic applications due to their tailored ignition and combustion properties. In particular, ball-milled Al/Zr composites exhibit lower ignition thresholds than pure aluminum, driven by exothermic intermetallic formation reactions and have demonstrated enhanced combustion properties. H...
This topic focuses on advances in and characterization of surface processed magnesium (Mg) alloys that demonstrated improved engineering properties relevant to industrial applications. The target engineering properties for Mg alloy surfaces can include corrosion and wear resistances, catalytic efficiency, and physical/chemical conditions promoting...
Biodegradable magnesium (Mg) alloys are promising for biomedical implants due to their favorable mechanical properties and safe degradation within the human body. However, the rapid corrosion of Mg remains a challenge, necessitating a deeper understanding of its behavior in physiological environments. This study evaluates the in vitro corrosion per...
With an increasing demand for biodegradable structural materials, magnesium (Mg) alloys stand out as promising candidates. Here, we investigate the corrosion-induced mechanical degradation of fine wires made from WE43 and ZX10 Mg alloys, evaluating their suitability for biomedical applications such as scaffolds, stents, and sutures. Both alloys exh...
This preprint explores the thermomechanical processing of the ZX10 magnesium alloy to enhance its mechanical performance and bio-corrosion resistance for biomedical implant applications. By evaluating extrusion (EXT), Equal Channel Angular Pressing (ECAP), and ECAP with low-temperature annealing (ECAP-A), the study demonstrates how microstructural...
Biodegradable magnesium (Mg) alloys are gaining attention for biomedical implants due to their favorable mechanical properties and safe degradation within the human body. However, the rapid corrosion of Mg remains a challenge, necessitating a deeper understanding of its behavior in physiological environments. This study examines the in-vitro corros...
Magnesium alloys are emerging as promising alternatives to traditional orthopedic implant materials thanks to their biodegradability, biocompatibility, and impressive mechanical characteristics. However, their rapid in-vivo degradation presents challenges, notably in upholding mechanical integrity over time. This study investigates the impact of hi...
Magnesium alloys offer immense potential as intelligent alternatives to traditional implant materials due to their inherent degradability, biocompatibility, and exceptional mechanical properties. However, their rapid deterioration hinders their practical applications, compromising their mechanical integrity. This study addresses this challenge by i...
Medical application materials must meet multiple requirements, and the designed material must mimic the structure, shape. and support the formation of the replacing tissue. Magnesium (Mg) and Zinc alloys (Zn), as a “smart” biodegradable material and as “the green engineering material in the 21st century”, have become an outstanding implant material...
Bone defects occur due to factors such as congenital anomaly, trauma, and osseous deficiency following resection of tumours. Biomaterials are required for bone augmentation of the lost bone architecture. Clinicians attempting to regenerate the tissue and restore its function and aesthetics because of trauma, pathology, or congenital defects face a...
The recrystallization behaviour of cold-rolled (CR) commercially pure (cp)-
titanium was investigated by experiments and simulations. The recrystallization
texture in cp-titanium depends upon the deformation texture. The
main texture components of the lower deformed (50% CR) material are
{1014}< 2131>, {1013}< 2131> and{1235}< 2311>, all having wea...
