Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

TOPOLOGICAL OPTIMIZATION OF THE TEST SPECIMEN FOR BIAXIAL TENSION
Problems of Strength and Plasticity, 2019 Applying the approaches of topology optimization, we consider the problem of substantiation of the configuration of the 2D test specimen, in the workspace of which the biaxial stress-strain state is realized. The original area occupied by the specimen is a square plate with a given side size made of an isotropic material.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects
Advanced Engineering Materials, EarlyView.This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
