Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

Advanced Engineering Materials, EarlyView.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐
