Boron determination in steels by Inductively-Coupled Plasma spectometry (ICP) [PDF]

, 1985
The sample is treated with 5N H2SO4 followed by concentrated HNO3 and the diluted mixture is filtered. Soluble B is determined in the filtrate by Inductively-Coupled Plasma (ICP) spectrometry after addition HCl and extraction of Fe with ethyl-ether.

Characterization of Carbon-Contaminated B4C-Coated Optics after Chemically Selective Cleaning with Low-Pressure RF Plasma [PDF]

, 2017
Boron carbide (B4C) is one of the few materials that is expected to be mostly resilient with respect to the extremely high brilliance of the photon beam generated by free electron lasers (FELs) and is thus of considerable interest for optical ...

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.

An investigation by LA-ICP-MS of possum tooth enamel as a model for identifying childhood geographical locations of historical and archaeological human from New Zealand [PDF]

, 2012
LA -IC P-MS (laser ablation-inductively coupled plasma-mass spectrometry) has been used to analyse enamel from the teeth of brushtail possum (Trichosurus vulpecula) in order to model a method for identifying the childhood geographical origin of human ...

Lifetimes, transition probabilities, and level energies in Fe I [PDF]

, 1991
We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe levels with energies between 25 900 and 60 758 cm . Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the range ...

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

Advanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Automated online preconcentration system for the determination of trace amounts of lead using Pb-selective resin and inductively coupled plasma-atomic emission spectrometry [PDF]

, 2006
An automated sequential-injection online preconcentration system was developed for the determination of lead by inductively coupled plasma - atomic emission spectrometry (ICP-AES). The preconcentration of lead was performed with a minicolumn containing a

Toward Maximum Utilization of Heavy Rare Earths in Sintered Nd–Fe–B Magnets by Grain Boundary Diffusion Source and Application Area Optimization

Advanced Engineering Materials, EarlyView.
In this work, the grain boundary diffusion process is optimized to maximize heavy rare earth utilization by strategic magnetic hardening of areas in the magnet such as corners or edges that are highly susceptible to demagnetization, as demonstrated by finite element magnetostatics simulation on an internal permanent magnet, synchronous traction motor ...
