Specifically, under tensile loading, the presence of mechanical constraints led to a notable increase in ultimate tensile strength (UTS) and yield strength as the gap size decreased, accompanied by a simultaneous reduction in fracture strain.
The load and displacement data were recorded continuously throughout the test and the engineering stress (σ) and engineering strain (ε) were calculated from them.

Three samples were used to obtain highly accurate data.
Meanwhile, there exist competing adsorption phenomena on steel surface when the solution contained H2S/CO2, the H2S adsorption amount on steel surface decreased with adding CO2, so the H2S poisoning effect on the hydrogen reduction reaction decreased, and then the amount of hydrogen atom into steel decreased.

Contrasted with PDF 75-0590 (Silicon) and Kauzlarich’s data [14], the sharp peaks mean the appearance of crystal silicon, while the gentle peak between 20° and 30° suggests that some amorphous silicon still exist.

The fundamental principle size
reduction in mechanical attrition devices lies in the energy imparted to the sample during impacts
between the milling media [9].
The values of particle sizes should not be confused with crystalline size, as is determined using XRD data values.

Introduction
Pursuit of weight reduction while meeting the better structural performance has become more intensive in aerospace industry; therefore more and more large monolithic components with thin walled structures are used in airframes instead of small parts joined by welding or riveting to obtain a higher strength-weight ratio.
The accuracy of FE cutting simulations depends on the comprehensive FE modeling, analysis approach and data used.

The presence of MgO after milling indicates either
incomplete reaction of Mg which after heavy milling forms an oxide upon exposure to air or
reduction of B2O3 to form MgO during milling.

K-means clustering algorithm was applied on the data set [16].
With the increasing applied stress the dislocation density increases, which leads to the reduction of the mean free path of dislocations and consequently to the drop of the AE signal level.
