The new way of using mechanical joint element (MJE) to cross the interface of new and old concrete to reinforce the combination is put forward.
When the new and old concrete strength grade is at certain range [6] , the length of the anchorage and the material of planting MJE are major factors to split strength of old and new concrete specimen.
Effects of surface agent on the shear strength: Table 2 indicates that: shear strength of the specimen with MJE was affected little by surface agent.
Summary 1) The reinforcing effect of MJE on split strength is remarkable; MJE plays an important role after debonding of the new and old concrete; the anchorage length of MJE is the main factor affecting the split strength of new and old concrete specimen. 2) The MJE can increase the shear strength of new and old concrete specimen greatly.

In the experiment, the welding thermal cycles under different cooling conditions with the peak heating temperature of 1320 o C were simulated via the Gleeble-1500D thermal/mechanical simulator.
The SH-CCT diagram of NM360 has been established by investigating the microstructure transformation course and the hardness of the welded heat-affected zone (HAZ) near fusion line during different cooling process.
Cold crack which arises in the welded heat-affected zone (HAZ) is the key factor to cause the poor weldability.
As a result, excellent combination property of welded joint can be obtained.
Cooling rate is a crucial factor in affecting the microstructures and properties of HAZ.

Packaging residual stress is key concern in terms of device reliability and performance [1], not only affecting structural integrity but also causing structural deformations that can affect device operation.
Strip Test In this work we carried out an especially designed test to investigate the mechanical properties of the adhesive under the actual mechanical conditions.

For instance, Hossein Mani et al. [1] evaluated the mechanical-thermal properties and microstructure of the RFW process using the finite element method.
Thermal properties change with temperature.
It reflects the degree of material deformation and loss during the process, directly influencing the mechanical properties and dimensional stability of the welded joint.
These areas are likely to experience phase changes, altering the material structure and affecting weld quality.
After 4 seconds, the curve stabilizes, reflecting that the deformation process has stopped as factors such as temperature and pressure have reached equilibrium.

The physical properties of cement are given in Table 1.
The Physical properties of fine aggregates are given in Table 2.
Coarse aggregates are typically used in concrete and other building materials, and their properties can significantly affect the strength and durability of these materials.
The Physical properties of coarse aggregates are given in Table 3.
Compaction factor test values for various mixes 3.3 Compressive strength: Compressive strength is one of the critical properties of concrete to be tested as it is linked with load carrying capacity and durability.

The number of cycles to failure (N) had been measured and compared in the case of different stress intensity factors.
The rating system The notch sensitivity of bandsaw blades is influenced by several factors.
The whole rating system has criteria for the base materials chemical composition, mechanical properties and for the manufacturing technology.
The factors, which have the strongest influence on notch sensitivity, can be seen on table 2.

The conductivity percolation threshold was found at 1000 mesh with enhanced mechanical and electrical conductivity properties simultaneously.
These factors can lead to weakened load transfer and compromised mechanical performance [11].
However, extremely fine particle sizes may result in weaker mechanical properties due to agglomeration or inadequate dispersion.

The mechanical property had the relationship with spatial arrangement of soil grains, mineral component and occurrence condition of diffluent salt.
The soil microstructure was an important factor to engineering characteristics.
The results showed that diffluent salt recrystallization affected soil internal structure.
The salty soil microstructure character was different before and after dehydrating, which changed the soil- mechanical property of salty soil.
At present, many scholars made soil test on mechanical property of salty soil by changing moisture and salt content[2] [3], less by microscope units transformation.

Introduction The presence of interstitial elements in metals may cause significant changes in their physical, chemical or mechanical properties [1-3].
Also, the equilibrium solid solubility of interstitial atoms has notable influence on the thermodynamic and mechanical properties of materials, such as solution strengthening [4,5], damping properties [6,7], etc.
Both the elastic and chemical factors affect the solubility and behavior of the interstitials.
And the mechanical properties of material can be estimated without the need to figure out the complex interactions between the interstitial and substitutional solutes.
