Influences of the Ag content on microstructures and properties of Zn–3Mg–xAg alloy by spark plasma sintering

Journal of Materials Research and Technology, 2023
In order to improve the comprehensive mechanical properties of Zn–3Mg alloy to meet application requirements of medical metal implants, spark plasma sintering (SPS) was adopted to prepare Zn–3Mg–xAg alloy (x = 0, 1, 1.5, 2, 2.5).

Temporal behavior of quantum mechanical systems [PDF]

, 1995
The temporal behavior of quantum mechanical systems is reviewed. We study the so-called quantum Zeno effect, that arises from the quadratic short-time behavior, and the analytic properties of the ``survival" amplitude.

Effects of power modulation on behaviours of molten pool and keyhole during laser–arc hybrid welding of pure copper

Materials & Design, 2020
Modulated laser power hybrid welding (M-HW) of 4 mm-thick T2 pure copper was conducted to improve the welding stability. It was observed that the sinusoidal modulation of laser power in hybrid welding can reduce the incidence of weld defects such as ...
