Potassium feldspar, phosphogypsum and coke are used as raw materials to obtain soluble salts of calcined sample through mechanical grinding, roasting activation and leaching with acid.
A study has been conducted on the factors that affect the leaching ratio of K2O of calcined samples, such as the type and concentration of leaching medium, temperature, time, liquid-solid ratio.
In order to explore the relationship between potassium dissolution rate and dissolution conditions, the effect of the four factors is mainly studied, such as leaching medium type, temperature, time, liquid-solid ratio on dissolution rate of potassium of the roasting samples.

Accordingly, the last decade has seen a tremendous interest in enhancing the mechanical properties of DP steels using micromechanical simulations of Representative Volume Element (RVE).
This is due to their superior mechanical properties compared to ferrite.

The laser process itself offers highly customizable parameters which affect the resulting materials properties [1].
Furthermore, mechanical properties were determined with those parameters and linked to the corresponding microstructure captured with SEM at 12000x magnification and EBSD imaging.
Since relative density is not the most relevant material characteristic from an industrial standpoint, it might be advantageous to model mechanical properties directly.
To determine which features would be suitable – other than global density/ porosity - we use machine learning (ML) to map the LPBF process parameters to mechanical properties after printing using a hybrid neural network architecture.
The mechanical properties of the printed samples were determined according to DIN EN ISO 6892-1 on the testing machine AllroundLine Z100 with robotic testing system roboTest L by ZwickRoell GmbH & Co.

The material property was known to be one of the most important factors that affected to the simulation accuracy.
The inverse method can be used to determine actual material properties, which is normally unobtainable from the experiment.
The method is highly interesting and can be applied to find proper material properties of a wide range of applications.
The inverse method involving gradient based on updating scheme was used to search for the actual mechanical property of non-pneumatic tire spokes.
This process was confirmed the authentic mechanical property of the radial spokes of the non-pneumatic tire.

The in vitro corrosion behavior of magnesium alloys is affected by many factors such as mechanical strain, temperature, surface area and solution transport conditions (e.g. flow rate).
Hence, the corrosion behavior of AZ31 is affected by the pre-strain from the result.
Therefore, it is considered that the corrosion behavior in fluid flow field is affected by the initial surface roughness. 3) The corrosion behavior was affected by fluid flow rate.

PFZ are believed to affect the mechanical properties of the
alloys in different ways [1].
It has also been observed that PFZ have no influence on the mechanical properties [4].
One of the reasons is that many microstructural factors near grain boundaries contribute to the mechanical properties, e.g. the width of PFZ, size of grain boundary precipitates and so on.
To predict strength and ductility of an alloy, therefore, it is essential to estimate the correlation between such mechanical properties and the corresponding microstructural factors.
Such a capability would be important for optimization of mechanical properties and design of new alloys.
