Advanced Engineering Materials, EarlyView.A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

The Astrophysical JournalWe study the spectral properties of the black hole X-ray transient binary 4U 1630–472 during its 2022 and 2023 outbursts with Insight-HXMT observations. We find that the outbursts are in peculiar soft states.

Optical Sources Near the Bright X-Ray Source in NGC 1073 [PDF]
Astrophys.J. 629 (2005) 233-238, 2005 New HST observations show that the bright X-ray source in the face-on spiral galaxy NGC 1073 is located near a ring of recent star formation with an age of 8-16 Myr. This strengthens the association of X-ray sources in spiral galaxies emitting near or above the Eddington limit for a 20 solar mass black hole with recent star formation events.

Understanding the X-ray luminosity function of high mass X-ray binaries [PDF]
, 2010 High mass X-ray binary luminosity function (XLF) is an important tool for studying binary evolution processes and also the mass loss and consequent evolution in massive stars. We calculate the XLF for neutron star binaries using the standard scenario for formation and evolution of these systems.

Assessing the Microstructure of SnBiZn 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 Sn40Bi and Sn40Bi2Zn 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.
