Thermally-induced α→β phase transformation interweaving with abnormal α grain growth in hot extruded TNM alloy

open access: yesJournal of Materials Research and Technology, 2021
The microstructural and crystallographic features of the β phase in TNM alloy during the hot extrusion at 1290 °C and the subsequent cooling process were investigated. Except the original grain boundary β phase, two categories of β particles, along grain

NEUTRON STAR MASS–RADIUS CONSTRAINTS OF THE QUIESCENT LOW-MASS X-RAY BINARIES X7 AND X5 IN THE GLOBULAR CLUSTER 47 TUC [PDF]

open access: yes, 2016
We present Chandra/ACIS-S subarray observations of the quiescent neutron star (NS) low-mass X-ray binaries X7 and X5 in the globular cluster 47 Tuc.

Management of Low Bone Mass in Female Athletes [PDF]

open access: yesKosin Medical Journal, 2014
As female athletic participation has increased, the positive effects of exercise on health have become evident. However, with this growth in sports activity, a set of health problems unique to the female athlete has emerged.

Tracing Embedded Stellar Populations in Clusters and Galaxies using Molecular Emission: Methanol as a Signature of the Low-Mass End of the IMF [PDF]

open access: yes, 2015
Most low-mass protostars form in clusters, in particular high-mass clusters; however, how low-mass stars form in high-mass clusters and what the mass distribution is, are still open questions both in our own Galaxy and elsewhere. To access the population of forming embedded low-mass protostars observationally, we propose to use molecular outflows as ...

Formation and composition of planets around very low mass stars [PDF]

open access: yes, 2016
Context. The recent detection of planets around very low mass stars raises the question of the formation, composition, and potential habitability of these objects. Aims.

On Low Mass AGB Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1991
Recent results on low mass AGB stars are presented. Observed amounts of AGB mass loss imply that thermal pulses will only be encountered for stars of initial mass less than about 4M⊙ for Pop I and 3 M⊙ for Pop II. Mc – L, Me – τif, and Mc – Tb relations are summarized.

The New Plastic Flow Machining Process for Producing Thin Sheets

open access: yesAdvances in Materials Science and Engineering, 2018
A new severe plastic deformation (SPD) process called plastic flow machining (PFM) was recently proposed to produce thin sheets with gradient structures.

Emergence of Nonwhite Noise in Langevin Dynamics with Magnetic Lorentz Force [PDF]

open access: yesPhys. Rev. E 97, 032117 (2018), 2017
We investigate the low mass limit of Langevin dynamics for a charged Brownian particle driven by the magnetic Lorentz force. In the low mass limit, velocity variables relaxing quickly are coarse-grained out to yield effective dynamics for position variables. Without Lorentz force, the low mass limit is equivalent to the high friction limit.

WHERE ARE THE LOW-MASS POPULATION III STARS? [PDF]

open access: yes, 2016
We study the number and the distribution of low-mass Population III (Pop III) stars in the Milky Way. In our numerical model, hierarchical formation of dark matter minihalos and Milky-Way-sized halos are followed by a high-resolution cosmological ...
