Prediction of Mechanical Properties of Ti-6AI-4V Titanium Alloy Bars Depending on Aluminum and Molybdenum Strength Equivalents Yu.B.
The following factors were analyzed: aluminum and molybdenum strength equivalents, standard mechanical properties (tensile strength σв, proof strength σ0,2, elongation δ, reduction of area ψ, impact toughness KCU), microstructure type and parameters (α-plate thickness bα, α-globule size aα), bar diameter, annealing temperature tann.
Pair and multiple correlation coefficients R were determined to estimate strength of the statistical connection between the studied factors.
According to the correlation analysis, annealing temperature, structure type and dimensions of structural components in the studied range barely affect mechanical properties of bars (correlations coefficients R < 0.3), most probably due to narrow change ranges.
The test of the proposed models demonstrated satisfactory correlation of estimated and actual values of mechanical properties of studied semi-finished properties.

The purpose of this research is to examine how the size and quantity of water hyacinth (WH) fibers impact their reinforcement of bio-based epoxy resin, with a specific focus on how these factors influence mechanical properties.
However, the main problems of bio-composites are the poor mechanical properties, limited barrier capabilities and thermal stability [8,9]. [8], [9].
In addition to modifying the surface of the fibers, it is essential to consider factors related to particle size.
