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 ...

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 ...

Structural Parameters Optimization of the Steel Bar Straightening Machine Based on the PSO Algorithm

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In the process of steel bar straightening processing, the straightening rollers are often damaged by fatigue due to uneven force, which causes frequent replacement of the straightening rollers. Therefore, the structural parameters optimization of the steel bar straightening machine is very important to improve the machining accuracy of the ...
