Results and Analysis The influence of Al-content on mechanical properties.
It can change the type, quantity of primary phase and the amount of eutectics, which affects the mechanical properties of alloy and casting defects.
Effect of temperature on the mechanical properties.
The influences of temperatures on mechanical properties can be seen in Figure 2 and figure 3, respectively.

Innovative ultra high-strength steels have excellent mechanical properties which commonly relate to the material’s martensitic microstructure.
Micrographs presented in Fig. 5 show that these improved mechanical properties come along with, or are caused by, a fine-grained martensitic microstructure of the steel.
Further experiments showed that the strengthening, and its values, were dependent on basically two factors, i.e. the applied strain and the temperature control during the quenching process.
Downstream heat treatment must be avoided in order to maintain the improved mechanical properties.
As a result, innovative thermo-mechanical hardening operations have been studied which provide even better mechanical properties than pure thermal treatment.

Understanding the mechanical properties of parts intended for MEX printing is crucial before starting the process.
Tensile test parameters, including strain rate, notably influence measured mechanical properties.
This can be attributed to two main factors.
The influence of printing parameters on selected mechanical properties of FDM/FFF 3D-printed parts.
Reducing print time while minimizing loss in mechanical properties in consumer FDM parts.

Moreover, with the increasing demand for materials with good performance, it becomes pertinent to develop ways that will counter these drawbacks without affecting the entire characteristics of the substrate.
One of the essential factors in laser surface cladding is the powder particle size.
The uniform distribution of SiC particles in the Al-Sn matrix had a good effect on its mechanical properties.
Mechanical Properties of Al-Sn-SiC Composite Coatings Research had been made to estimate the mechanical properties of materials from bulk hardness measurement ever since indentation testing has come into existence, especially yield and tensile strengths [27].

The mechanical properties of the AZ31B alloy sheets processed by differential speed rolling (DSR) from the cast ingots homogenized at two different conditions were investigated.
However, there are few studies on the effects of homogenization of the cast ingot on the microstructure and the mechanical properties of the subsequently hot-rolled magnesium alloys, and the optimum homogenization condition is still unclear.
The DSR processing is a potential technique for enhancing the mechanical properties and the formability of the magnesium alloys [9,10], but it is more sensitive to the hot workability compare with the normal symmetric rolling because of the severe shear deformation.
In this study, a DSR processing was carried out on the AZ31B alloy cast ingots homogenized at different conditions in order to investigate the effects of homogenization on the mechanical properties of the hot-rolled sheets.
Therefore, the differences in the mechanical properties of the DSR processed sheet can be considered mainly due to the distribution of the Al and Zn in the matrix in the present work.

Among them, the inorganic fillers play an important role in the mechanical properties[2,3].
Some of the factors influenced the cured depth of composite resins.
The ratio of inorganic filler and cured depth also affect the mechanical properties of composite material.
The former plays an important role in mechanical and chemical properties.

After spot welding, important changes occur in mechanical and metallurgical properties of the spot welded areas and heat affected zones.
Weldability of dual-phase steel is one of the key factors governing its application in automotive industry.
The spot weld quality is affected by several factors, including: electrical current, pressing force of electrodes, welding time, material of electrodes, thickness and material of the joined sheets.
Experimental studies on weld nugget formation provide relevant information about the influence of different welding parameters on weld properties.
The utilization of a finite element base model to quantify the effects of RSW parameters on weld properties of dual-phase steel was verified in [7].

The microstructure and mechanical properties of the joints obtained with different heat input were analyzed.
More energy and environment factors have been taken into consideration to pursuit the maximizing of benefit.
When joining the two different metals brittle intermetallic compounds at the interface formed by reaction between aluminum and iron and the brittle compound seriously affect the mechanical properties of joints[2], so joining aluminium to steel is difficult and challenging.
The microstructure and the phase constitution were studied by OP, SEM, EDS and XRD, and the mechanical properties of the joints were also analyzed.

The classification of mineral additives used in cementitious materials is dependent on many factors such as morphology and composition, but it also depends on the kinetics of the reaction with calcium hydroxide, also known as its pozzolanicity.
The results show that the mechanical tests are more affected by the substitution content than by the nature of the substitution.
The indirect methods measure a physical or mechanical property of the sample that indicates the extent of pozzolanic activity (tests of mechanical strength, electrical conductivity, thermogravimetry, and heat by conduction) [1].
Several factors influence the mechanical results, such as water/cement ratio, level of cement substitution, curing time, and type of substitution.
However, the substitution material (ground quartz or silica fume) does not significantly affect the outcome.

Its basic mechanical properties are studied by the cube compressive strength test, the drying-wetting cycle test and flexural strength test and compared with the ordinary concrete in the same sand ratio.
Its goal is to study the basic mechanical properties of inorganic polymer concrete whether adding mineral powder and to be compared with the same level of ordinary concrete.
All of these factors bring about the decrease of the bending tensile strength of thespecimens.
So it has adversely effect on its toughness properties.
