Trans‐Conductive Melt Pool Scaling and its Implications for Parameter Transfer in Laser Powder Bed Fusion for Metals with High Thermal Diffusivity

Advanced Engineering Materials, EarlyView.
Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Millisecond Oscillations in X-Ray Binaries [PDF]

Annual Review of Astronomy and Astrophysics, 2000
▪ Abstract  The first millisecond X-ray variability phenomena from accreting compact objects have recently been discovered with the Rossi X-ray Timing Explorer. Three new phenomena are observed from low-mass X-ray binaries containing low-magnetic-field neutron stars: millisecond pulsations, burst oscillations, and kilohertz quasi-periodic oscillations.

Assessing the Microstructure of SnBiZn Alloys during Semisolid Treatment

Advanced Engineering Materials, EarlyView.
The development of Sn‐based alloys for semisolid processing is crucial for Industry 4.0. This study investigates Sn40Bi and Sn40Bi2Zn alloys, revealing that Zn refines Sn‐rich globules by pinning dendrite boundaries. Bi saturation occurs at 60 min, while Zn enhances globule microhardness at 90 min through solid solution strengthening.
