Moreover, non-equiatomic compositions may offer even better properties [15, 12].
There was lack of consensus yet on factors responsible for the anticipated decelerated diffusivities.

Steel is typically regarded as a more cost-effective and preferred building material in industrial sectors [4-5], because mild steel is inexpensive and has excellent mechanical properties.
The widespread use of mild steel is linked to its appealing qualities, which include strength, durability, excellent mechanical and chemical properties, availability, and a relatively low cost of manufacturing [1, 6–8].
This is a widespread issue that not only increases the risk of accidents because of a decline in mechanical properties but also results in significant financial losses.
It functions as a wetting surfactant with surface tension-lowering properties [21, 40].

Introduction The grain microstructure of crystalline solids decidedly determines its physical and mechanical properties.
This driving force does not depend on boundary properties and moves a boundary from a grain with lower free energy towards grain with a higher free energy.
Grain boundaries can also be driven by an applied mechanical stress.
This is achieved by utilizing orientation dependent properties and their discontinuity at the grain boundary.

From the analysis of the above arch bridge damages, the main types of damages of metal sheath were corrosion and internal cracking of cement mortar caused by environmental factors.
Fig. 1 Commonly encountered damages in cable There are following causes of common damages in cable body protection measures: 1) The production process and mechanical characteristics of cable members.
All the methods above could detect the cable corrosion, but all methods were indirect ones except for the fenestration detection method, which indirectly judged the corrosion degree of the cable body by measuring the physical factors related to the corrosion.
Uneven cable force, cable corrosion, wire breaking and cracking Magnetic flux method Detect changes of flux by small electromagnetic sensors, Calculate the cable force and the degree of cable damage based on the relationship between temperature and flux. 1) Advantage is that it will not affect any the mechanical and physical properties of cable except for magneticing cable, 2) The disadvantage is that you must field calibration underr the interference from temperature and electromagnetic field.
Main damage encountered in metal sheath is corrosion and internal cement mortar cracking caused by environmental factors; Main damage encountered in organic sheath are aging, cracking caused by external load, long-term high stress and others.

This in turn affects the drivetrain and the gearing which also affects the vehicle engine performance.
The proposed mining vehicle tyre design provide an opportunity to conform to the original specified loading conditions plus providing some allowance or factor of safety for harsh mining conditions.
The material properties were adjusted in the Ansys® model to provide similar results to these experimental results.
Therefore the same homogenous material properties was used as defined in the pneumatic tyre material structure.

Lu et al., (2024) [33] examined the effects of many factors on TSP and proposed a novel approach that incorporates the processing and collecting of data from these sources.
These include Vp, Vs, Poisson’s ratio, and various mechanical properties such as Static and Dynamic Young’s modulus, Shear modulus, and Bulk modulus.
The Poisson’s ratio ranges indicate elastic properties of the rock mass, and zones with higher values might correspond to saturated or deformable areas.
The data also showed that the velocities of seismic waves had significant dependence on the mechanical properties of the rock, which proved to be good relations for weak or hazardous zone identification.

To explain this failure, Soda [16] explained two factors; one is the clearance between the ring and the shaft or housing, and the other is the elastic deformation which Imai [17] proved experimentally.
Then, in the previous studies [13-15], the amount of the slip was investigated by varying several design factors such as shaft deformation, motor torque and shrink-fitting ratio.
It is confirmed that the rigid body size at the center does not affect the result, and the diameter 8 mm is used.

The sprayed particles size distribution is also very important for coating properties [189].
Coating properties.
It has been found that this transition temperature depends on numerous factors: i) the modification of the substrate surface wettability, ii) desorbtion of adsorbates and condensates and iii) solidification mechanisms [216, 220].
Nevertheless, many works are still necessary to correlate coating thermo-mechanical properties to in-flight particles characteristics as well as substrate and coating temperature during spraying.
For larger droplets, shell precipitation occurs and the particle can later fragment depending on the pressure inside the shell and its mechanical properties.
