Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Nonmetric traits in permanent teeth as clues to ethnicity in vidarbha subpopulation to aid forensic profiling: Pilot study

Journal of Forensic Science and Medicine
Introduction: Nonmetric dental traits have a crucial role in ethnic classification of populations that help in forensic racial identification. Many studies have demonstrated the differences in the expression and frequency of dental traits between various

Two Crusafontina (Mammalia, Insectivora) fossils from the Miocene of the Transdanubian Central Range (Hungary) [PDF]

, 2008
Two isolated teeth of Anourosoricini shrews, Crusafontina (Mammalia, Insectivora, Soricidae) are present in this paper. A complete left maxillary molar was found in the Sarmatian (Middle Miocene) locality of Várpalota Lignite Mine, Pit III.

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

Advanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

Thermal oxidation kinetics of additive free polyamide 6-6 [PDF]

, 2013
Thermal aging of an additive free PA 6-6 has been elucidated at 90, 100, 120, 140, 150 and 160 C in airventiled ovens by Fourier transform infrared spectrophotometry, viscosimetry in molten state and uniaxial tensile testing.

Influence of Heat Treatment on Microstructure and Mechanical Properties at Elevated Temperatures of Nonweldable Ni‐Based Alloy Printed by Fused Filament Fabrication

Advanced Engineering Materials, EarlyView.
The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.

Assessment of Number of Cusps and Occlusal Groove Pattern in the Primary Mandibular Molars: An Observational Study

Journal of Nepal Medical Association
Introduction: Primary mandibular molars have diverse morphological variations. This trait of human dentition is very important for restoring the anatomy of the tooth as well as for the anthropological study to characterize the ethnicity.

Fusion of the 2nd maxillary molar with the impacted 3rd molar

Bratislava Medical Journal, 2012
Subject matter: The dentist has to deal with complicated cases of fused molars, which are rather rare and morphologically very varied. A wrong or incomplete diagnosis can considerably complicate a planned therapy.The authors describe a case of apical periodontal complication of fused teeth that had to be removed surgically.

Impact of Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

Advanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.
