Microstructural Evolution and Mechanical Property Degradation of Sn0.5Ag0.7Cu5Bi Solder Joints with High Indium Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

(Nb,Ti)(C,N)‐Precipitates in High‐Strength Low‐Alloyed Steels—Modeling, Characterization and Validation

open access: yesAdvanced Engineering Materials, EarlyView.
Steel samples are investigated using complementary simulations and measurements. Transmission electron microscopy in bright‐field mode, combined with energy‐dispersive X‐ray spectroscopy maps for titanium and niobium, reveals distinct particle populations. Simulations reproduce these in size and composition.

Additive Processing of Ti‐17 by Wire Arc Directed Energy Deposition: An Investigation of the Microstructure and Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
This study focuses on processing the titanium alloy Ti‐17 using wire arc directed energy deposition (waDED), with an emphasis on the microstructure and mechanical properties. The waDED typical heat‐affected zone banding is characterized and related to the local mechanical properties.

O periegeză prin istoricul cercetării protistorice dobrogene: necropolele“ de tip Murighiol” [PDF]

open access: yesPeuce, 2014
Dobrudjan necropolises from 4th-3rd c. BC have been researched for the past six decades. The first diggings at Murighiol (1954-1958) were shortly followed by investigations at Satu Nou (1958-1959) and Telița (1959).
