Effects of Creep in Titanium at Room Temperature during Tensile and Profilometry‐Based Indentation Plastometry Testing

open access: yesAdvanced Engineering Materials, EarlyView.
This article concerns room temperature tensile testing, with a range of (nominal) strain rates, of three titanium alloys. Stress–strain curves are analyzed to obtain creep characteristics. Profilometry‐based indentation plastometry testing is also covered, using different penetration velocities, and correlations established with tensile data.

Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.
