Article Synopsis
- Aging is crucial for improving both strength and ductility in selective laser melted (SLM) precipitation hardening steels, particularly 17-4 PH steel.
- The study examined how different aging temperatures and durations affect the microstructure and mechanical properties of SLM 17-4 PH steel, finding that aging led to larger martensite grains and an increase in the austenite phase.
- While the ultimate tensile strength increased with longer aging times, ductility decreased sharply, highlighting the need for careful heat treatment to optimize performance in high-performance steels.
Rare earth nickel-based perovskite oxides (NiO) have been widely studied over recent decades because of their unique properties. In the synthesis of NiO thin films, a lattice mismatch frequently exists between the substrates and the thin films, which may affect the optical properties of NiO. In this paper, the first-principles calculations were employed to study the electronic and optical properties of NiO under strain.
