Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra
The Astrophysical JournalWe present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...

Photometric Studies of the Contact Binary BV Draconis [PDF]
Journal of Astronomy and Space Sciences, 1999 We performed CCD photometric observations of W UMa type contact binary BV Dra during eight nights from May 1996 to June 1999 using 61cm telescope at Sobaeksan Optical Astronomy Observatory, and completed BVR light curves of the system.

Twin Binaries: Studies of Stability, Mass Transfer, and Coalescence
, 2011 Motivated by suggestions that binaries with almost equal-mass components ("twins") play an important role in the formation of double neutron stars and may be rather abundant among binaries, we study the stability of synchronized close and contact ...

A Application of WD Model to EB Type Contact Binary System [PDF]
Journal of Astronomy and Space Sciences, 2000 The EB type contact binaries show large temperature difference ( T 1,000K) between two components. Thus we have modified the mode 3 of the WD program to adjust albedos, limb darkening coefficients and gravity darkening exponents for both components of ...

New Photometric Investigation of the Solar-Type Shallow-Contact Binary HH Bootis
Advances in Astronomy, 2019 The short-period solar-type contact binary HH Boo was monitored photometrically for about 8 years. It is found that the CCD light curves in the B, V, R, and I bands obtained in 2010 are symmetric, while the multicolor light curves observed in 2011 and ...
