This results in semi-coupled thermo-mechanical models in a Lagrangian frame, where the thermal field is calculated prior to the mechanical field by separating the two analyses.

While thermo-mechanical treatments given to these alloys
optimise their mechanical properties, they also result in materials that are susceptible to IGC.
Although the relationship between grain shape and anisotropy in localised corrosion appears clear, other possible contributing factors have not been considered (e.g. texture, particle distributions, stresses).
Thus, because texture can affect the distribution of solute at the grain boundary and regions adjacent to it, there are certain implications for the development of IGC.
The crystallographic relationship between the grain boundary and the precipitate habit plane can affect precipitate morphology [12] and density [13].
Texture may affect whether grain boundaries are susceptible to IGC and the likelihood that IGC will deviate in another direction.

This structure gives ZnO its unique properties that exhibits several properties such as optical properties, electrical properties, piezoelectricity, thermal stability, chemical stability, antibacterial properties, UV absorption, and photocatalytic activity.
The choice of synthesis method depends on factors such as the desired particle size, morphology, and purity of the final ZnO product, as well as the specific application requirements.
It's worth noting that the specific properties of ZnO can vary depending on factors such as its synthesis method, crystal structure, and doping elements used.
Overall, the results suggest that the introduction of Ag into the ZnO-Ag composites significantly affects their optical properties, leading to improved absorbance characteristics in both the UV and visible regions [18-20].
The value of A is determined by factors such as the index of refraction and the effective masses of electrons and holes.

How to enhance mechanical
properties of ceramic tool materials becomes imperative.
However, mechanical properties are dependent on many factors including components, content and fabrication process, which make it difficult to develop ceramic materials.
The macro mechanical properties of composite ceramics are intimately related to their microstructures.
Computer-based multi-scale coupling model is applied to simulate the microstructure and mechanical properties of ceramic materials in order to study the influence of components, microstructures and fabrication process on mechanical properties.
In order to optimize fabrication process and achieve excellent mechanical properties, combining simulation methods with actual fabrication process and associating mechanical properties with microstructure is critical and forms the focus of the future study.

Covalent electron and lattice electron are closely related to the mechanical properties and thermal properties of structure material.
Different content of each element, lead to the different lattice constant of the average atom, thus affecting their crystal structure formed by high entropy alloys.
The method based on EET can get the near results, which have 7%, 5% and 2% deviations, and further we can analyze the mechanical properties using EET.

Previous research suggested that pore morphology and direction greatly affected bone ingrowth behavior [4, 5].
This method can be useful to fabricate porous implant materials possessing aligned pores and control the porous structure (e.g., pore size, porosity), which is one of the predominant factors for determining mechanical properties, such as Young’s modulus in particular.
In this study, porous structures of Ti-6Al-4V alloy with uniaxially and orderly aligned pores were fabricated using the EBM method for biomedical applications, and their microstructural and mechanical properties were evaluated.
For the evaluation of mechanical properties such as Young’s modulus and yield stress, compression tests were conducted using a mechanical testing machine (AG-X, Shimadzu) under the crosshead speed of 1.67 × 10−4/s.
The mechanical properties of such porous materials can be optimized or customized by changing the porous structure such as the grid spacing and wall thickness by using the EBM method.

Testing Design
This test mainly observes effects that factors of electrode pressrue( F ), welding current( I ) and welding time( t ) may bring to the joint property and meanwhile design 3 levels for the 3 factors separately.
The experiment is designed according to four factors and three levels orthogonal table and aims to find out the effects that all factors may bring to testing subjects and distinguish main influencing factors with minor ones then try to seek out better manufacturing conditions or the best combination of the statistics.
factors can be listed from major ones to minor ones as t > O > I > F and the best combination of statistics is F2I3t2O2.
Shrinkage cavity, which could worsen mechanical property of spot-welded joints and probably cause cracks that will lead to maximum durable intensity regression of joints, was formed in later period of nugget solidification (See Figure 7).
Microhardness test of Joint Hardness number of joints is considered as an extraordinarily important indicator to judge quality of joints in researching mechanical property of welding joints because hardness number directly determines anti-deformation and anti-destruction capacity of the joints.
