Anisotropy of Boride Layers: Effect on the Mechanical Properties of AISI 4140 Borided Steels I.
It was determined that the anisotropy of borided phases reveals a significant instability of properties in service.
One of the techniques to determine the effect of anisotropy on the mechanical properties of boride layers is the induced-fracture by Vickers microindentation.
Both sublayers exhibit a (001) texture, that leads a well-expressed anisotropy of the thermophysical properties of the layers [8].

In addition to residual stress, there are other factors acting important roles to the warpage.
Warpage is an integrated reflection of several deformations caused by multi-factors.
So its capability to resist deformation caused by outside factors will become weak.
The logic relationships of many influence factors were clarified.

When materials are processed using ECAE, several different factors influence the workability and the microstructural characteristics of the as-pressed billets.
FEM employed to simulate and study the influence of various factors affecting the ECAE process as well as the mechanical behavior of as-processed materials [3].
The number of ECAE pass and different die angles considered as the variables affecting the strain conditions in this research study.
The change in material properties is dependent on the evolution of equivalent plastic strain (PEEQ) in each pass.

The roughness of surfaces on 3D-printed parts is affected by various factors, such as CAD to STL conversion, layer thickness, printing speed, and temperature.
In addition, surface roughness affects the fatigue properties of components under cyclic loading conditions, highlighting the importance of selecting the appropriate manufacturing orientation for optimum performance.
Methodology In this section, we will explore the factors that impact the surface roughness of a part produced by additive manufacturing.
The thickness of the layer plays a significant role in affecting the part's print time and ultimate tensile strength.

Samples were characterized by DSC, XRD, SEM, UV-Vis-NIR and fluorescence spectra and the factors affecting the crystallization of glass ceramics were analyzed.
The results indicated good crystallization property of ZBS glass ceramics.
Glass ceramics, as new functional materials, possess not only high mechanical strength, good thermal and chemical stability and dielectric properties, but also excellent optical performance, with a variety of applications in optoelectronics and laser technology[3-7].
The most important factors affecting the performance of glass ceramics are the type of the main crystalline phase and the grain size.

Introduction Punching is widely used in the mechanical industry as a processing method, material processing through a large elastic-plastic deformation, material properties of tools and process design is the largest factor to consider [1-4].
According to the most common normal distribution, the probability distribution of mechanical properties of the influence of punching force are analyzed, the theoretical support is given.
