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

Advanced 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.

The Fluid Flow between Differentially Rotating Non-Concentric Spheres [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2016
The motion of a viscous incompressible fluid between two non-concentric spheres, which rotate with different angular velocities, is considered. The axes of rotation of spherical surfaces are parallel and spaced apart by a small distance.

Electrospark‐Deposited AlCrFeCoNi High‐Entropy Alloy Coatings on Steel: Microstructure Evolution, Mechanical Properties, and Corrosion Response

Advanced Engineering Materials, EarlyView.
AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.

PRESSURE AND PRESSURE DERIVATIVE ANALYSIS IN A RESERVOIR WITH A FINITE-CONDUCTIVITY FAULT AND CONTRAST OF MOBILITIES

Revista Fuentes El Reventón Energético, 2013
Finite-conductivity faults present a very unique transient behavior. In general terms, as the fault is reached by the pressure disturbance the pressure derivative falls with forming a straight line with a slope of minus one, then ...

Optimizing Laser Ablation of Stainless Steels for Volume Removal and Surface Quality Using Burst of Pulses

Advanced Engineering Materials, EarlyView.
This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...
