Formation of Diffusion Layer on Ti-6Al-4V Alloy during Longtime Friction with Al

open access: yesMetals, 2019
Elements’ diffusion between Ti-6Al-4V alloy and Al in the process of sliding was investigated from 400 °C to 600 °C. The results showed that the atoms were diffused at the Ti-6Al-4V/Al interface.

A model for multi-quark systems [PDF]

open access: yes, 1997
As a step towards understanding multi-quark systems abundant in nature we construct a model that reproduces the binding energies of static four-quark systems. These energies have been calculated using SU(2) lattice gauge theory for a set of six different

Reliability and Inference for Multi State Systems: The Generalized Kumaraswamy Case

open access: yesMathematics, 2021
Semi-Markov processes are typical tools for modeling multi state systems by allowing several distributions for sojourn times. In this work, we focus on a general class of distributions based on an arbitrary parent continuous distribution function G with ...
