Effect of arc re-melting on microstructure, mechanical and tribological properties of commercial 390A alloy
(Elsevier, 2021)
To investigate the effect of the arc re-melting on the microstructure, mechanical and tribological properties of the 390A alloy, its ingot produced by the conventional induction melting method was subjected to the arc ...
Effect of boronizing on operating stability of steel AISI 304L under erosion impact of hard particles
(Springer, 2021)
The effect of solid boronizing at 950 degrees C for 2 and 4 h on the phase composition, microstructure, hardness and abrasive wear of steel AISI 304L is studied under the impact of a flow of hard particles. The boronized ...
Machine learning models to estimate the elastic modulus of weathered magmatic rocks
(Springer, 2021)
In recent years, several soft computing models have been proposed to estimate the elastic modulus of magmatic rocks. However, there are lacks in models that consider the different weathering degrees in determining the ...
