Study of an Mg90Y7Zn3 alloy (WZ73) in sodium chloride solution — An analysis by correlated polarization and climate chamber testing

Engineering Reports, Volume 4, Issue 7-8, July-August 2022., 2022
From the polarization tests, the expected increase in corrosion sensitivity was observed when the NaCl concentration increases and the critical sodium chloride concentration for pit initiation was notified in the range 10−4–10−3 mol/L. For NaCl concentrations higher than 10−4 mol/L, the corrosion attack at the WZ73 magnesium alloy is characterized by ...

Hot crack susceptibility of cast Mg97Y2Zn1

Engineering Reports, Volume 4, Issue 7-8, July-August 2022., 2022
Formation of hot cracks in alloys is a critical issue for their production and processing. In this study, the susceptibility of the cast Mg97Y2Zn1 alloy containing long period stacking ordered structures to hot cracking was investigated using tensile tests in a Gleeble testing machine, and described in terms of the brittle temperature range (BTR ...

Analysis of defects in a twin roll cast Mg‐Y‐Zn magnesium alloy

Engineering Reports, Volume 4, Issue 7-8, July-August 2022., 2022
In this work, a Mg‐Y‐Zn alloy containing LPSO structures was twin roll cast with different process parameters, and the defects that arose were investigated. In particular, defects such as surface bleeds, center‐line segregations, and deformation segregations in the mid‐thickness of the strip were observed and analyzed with regard to the TRC parameters ...

Mechanical properties and failure mechanisms of Mg-Zn-Y alloys with different extrusion ratio and LPSO volume fraction

Journal of Magnesium and Alloys, 2022
In long period stacking ordered (LPSO) phase containing Mg-Zn-Y alloys, high elastic modulus and deformation kinks of LPSO phase considerably enhance the tensile yield strength, with slight detriment of or benefit to the ductility depending on its volume

Design and Analysis of Intelligent Agricultural Monitoring System Based on Biological Intelligence Optimization Algorithm

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The traditional optimization method has insufficient intelligence, slow operation speed, and some problems in the calculation of optimal parameters when facing the relationship between too large sample size and complex thread. The biological intelligence optimization algorithm is based on the genetic and evolutionary mechanism of the genetic system ...
