Its mechanical properties such as strength and toughness to achieve a very high level of the Cr-Co-Mo-Ni bearing steel, because of containing many kinds of alloy elements (≥30%).
But due to the same reason, the mushy zone range is expanded, and the grain is coarsened, and the homogeneity of the alloys is decreased, due to the enrichment of high content of alloying elements in front of the solidification, in the solidification process of smelting, which eventually leads to the difference of the material properties [2].
The non-zero interpolation factor was distributed between CA unit cell and FE node of the finite element mesh respectively, and the grid cell in the temperature in unit cell of respectively was determined combine with these factors such as finite element node temperature.
Update the node temperature at nodes on the branches crystalline core, the growth process of the release of latent heat summation, using the same interpolation factor.
This directly affects the performance of the ESR ingot solidification structure.

Due to the exceptional properties of these superalloys their machining becomes very difficult and time-consuming; They damage the cutting tool, and excessive use of lubricants eventually affect the material handling and cost.
Introduction Nimonic and other nickel-based alloys are promising materials for use in nuclear and gas power plants for turbine components due to their exceptional mechanical and thermal properties [1].
The advanced properties of these Nickel-based superalloys make them very difficult to machine, and therefore, their machining costs are sometimes unbearable [2].
The solid lubrication technique effectively increases the machinability of the Nimonic 90 superalloy; however, future work needs to be done in this domain such that the lubricative material, method, and economic factors are equally considered.

Due to the influence of many factors for the strength of cement stabilized soil that make the test results apparently complex and no significant relationship exist.
But a large number of training iterations may force a neural network to over train, which may affect the predicting capabilities of the model.
Training sample Because the strength of the cement soil include many influencing factors in the model, In this paper related parameters include mixing ratio, age, water content, porosity, saturation and wave velocity and dry density, The seven parameters are input variables, that is used for modeling the input variables a seven dimensional vector, and output is cement soil strength.

The earthquake is the main factor causing serious damage of ancient pagodas.
In the current, the strengthening technology applied modern steel to hoop brick masonry of pagoda is widely used, which is effectively to improve the whole mechanical properties of the structure.
Lesser cross section and vertical compressive stress are the main factors led to shear and rupture failure of top masonry of pagoda under the repeated earthquake action.
Among them, weathering and salt efflorescence is the most important factors.
The durability of mortar is affected by hot and cold, dry and wet, freeze-thaw and other environmental factors.

Methods for describing complex materials, as well as the nature, characteristics, and changes of the material after being affected by the environment, especially the influence of the structure of the material on the macroscopic properties of the material.
The object examined by classical elastoplastic theory is homogeneous, continuous, and infinitely separable materials, that is, materials that maintain their original characteristics and properties no matter what scale they are.
Due to their structure, the characteristics, characteristics, or properties of materials are complicated.
The microscopic and mesoporous characteristics of the rock and soil porous medium strongly affect its macroscopic characteristics.
For example, its macroscopic properties such as impermeability, durability, strength, and deformation properties are closely related to the microscopic and mesoporous characteristics.

These advanced materials are broadly applied in the aerospace industry due to their excellent mechanical properties.
In fact, the chip thickness (or shear plane angle) depends on different properties of materials and different conditions of machining.
Discussion of the main influencing factors of serrated chip formation The properties of workpiece material always play a key role in the chip formation.
In general, the materials with high hardness and low thermal physical properties, such as heat-treated alloy steels, titanium alloys and super alloys, can form serrated chips in a wide range of cutting speed.
In order to determine the most critical factors, we have quantitatively analyzed the influences of most principal cutting parameters by a series of finite element simulation and result comparison.

Nevertheless, few researches investigated the relationship between these properties.
In addition to porosity evaluation, the rheological properties of raw materials have shown links to the technological properties of bricks in their final state.
Rheology deals with the viscoelastic properties of matter.
Rovnaník et al. [17] prepared and studied in terms of mechanical and rheological properties a binary geopolymer system used as cementing material composed of metakaolin and waste red brick powder.
Fig. 5 and fig. 6 show the loss factors of the prepared suspensions, with 40 and 50 wt.% water content, respectively.

However, not all bituminous binders show properties required for utilisation in foamed bitumen.
The water content of the recycled mix was determined according to the modified Proctor test and it is the most important factor from the perspective of mixing (quality of aggregate coating by binder, binder dispersion), compaction and resulting mix properties perspective.
It can be concluded that the effect of ERm on mix properties is more dominant than that of HLT.
It is necessary to examine, how these parameters correlate with the resulting properties of cold recycled mixes.

Carrageenan can form a gel with weak (brittle) mechanical properties.
Carrageenan-based hydrogels have good mechanical properties that allow them to absorb water [15].
The primary factor affecting the superabsorbent's ability to absorb water was cross-link density, and the relationship between the two was inverse [23].
