Nanoindentation response of laser shock peened Ti-based bulk metallic glass

AIP Advances, 2015
The effect of laser shock peening (LSP) on mechanical properties of Ti-based bulk metallic glass (BMG) was investigated under nanoindentation. Two regions were generated within the specimen after the LSP: (I) the extremely thick softened region (∼300 µm)

Localized Defects in Cold Die-Compacted Metal Powders

Journal of Manufacturing and Materials Processing, 2022
In powder metallurgy (PM), the compaction step is fundamental to determining the final properties of the sintered components. The deformation and defectiveness introduced in the powder material during uniaxial die compaction can be correlated to the ...

Sintering Improves the Mechanical Properties of Fluorapatite Scaffolds With Open Porous Gyroid Architecture

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT Synthetic scaffolds are needed to overcome the limitations of autografts and allografts for the treatment of critical‐sized bone defects. However, fabricating scaffolds with both high porosity and adequate mechanical stability for load‐bearing applications is difficult.
