Influence of Laser Beam Power on the Temperature Distribution and Dimensions of the Molten-Pool Formed during Laser Boriding of Nimonic 80A-Alloy

Crystals, 2023
Laser boriding is a surface treatment that involves the simultaneous re-melting and mixing of the alloying material, containing amorphous boron blended with diluted polyvinyl alcohol, with the substrate material (Nimonic 80A-alloy).

Electron transport, penetration depth and upper critical magnetic field of ZrB12 and MgB2

, 2004
We report on the synthesis and measurements of the temperature dependence of resistivity, R(T), the penetration depth, l(T), and upper critical magnetic field, Hc2(T), for polycrystalline samples of dodecaboride ZrB12 and diboride MgB2.

Superconducting borides [PDF]

AIP Conference Proceedings, 1991
A number of superconductors are found among binary and ternary boride compounds. The highest {Tc}'s are often fund near a limiting composition for the compound's stability. Ternary borides have been a fertile area for exploring the interaction between superconductivity and magnetism, and appear to be the area in which further aspects of boride ...

The effects of chemistry variations on hot cracking susceptibility of Haynes® 282® for aerospace applications

Materials & Design, 2023
Hot cracking susceptibility of Haynes® 282® with varying amount of C (0.05–0.09 wt%), Mn (0.03–0.12 wt%), Si (0.03–0.16), B (0.005–0.006 wt%) and Zr (0–0.01) are investigated. Synergistic role of C and B is found on solidification and heat affected zone (

Comparative experimental and Density Functional Theory (DFT) study of the physical properties of MgB2 and AlB2

, 2011
In present study, we report an inter-comparison of various physical and electronic properties of MgB2 and AlB2. Interestingly, the sign of S(T) is +ve for MgB2 the same is -ve for AlB2. This is consistent our band structure plots.
