Investigation of the Mechanical Properties and Microstructure of Graphene-Aluminium Alloy Composite Fabricated by Stir Casting Process A.
However, average mechanical properties and low wear resistance are the prominent drawbacks of aluminium alloys.
GNPs with excellent mechanical properties were introduced in aluminium alloy with various amounts of GNPs in wt%.
Poor dispersion of GNPs is one of the factors that could be affecting the mechanical properties of the composite.
Two main contributing factors in hardness enhancement are uniform distribution and densification of composite[11].

The effect of hot forging reduction ratios (1.11 and 1.29) on the hardness and mechanical properties are studied.
Good mechanical properties can be obtained by a combination of plastic deformation and thermal treatment.
Heat treatment is one of the major factors used to enhance the mechanical properties of low alloy steel.
An aging treatment before warm working is essential to the development of better mechanical properties.
Optimum mechanical properties can be obtained when heat treatment is carried out following TMT. 6.

General Situation of Experiment When designing the experimental programme, various factors[1] should be considered to affecting the load-carrying capability of unbonded prestressed slabs, such as strength grade of board, the number of prestressed tendons and non-prestressed bar, the line form and loaded way of prestressed tendons, and so on.
properties of unbonded prestressed plate are list in table 2.
Calculation of ultimate bearing capacity[2][3] Through the analysis of the existing experimental result, there are many factors affect the ultimate bearing capacity of slabs with opening hole[4], such as location of hole, size of the hole, shape of hole, boundary condition, load type and so on.

These changes affect properties resulting in either increase or decrease of performance and serviceability.
A substantial amount of research has been done to understand the factors affecting the strength and mechanical properties of AAC [8-13]; however limited and conflicting data have been found towards understanding the cracking behavior of AAC.
The curing time, degree of restraint, environmental factors constitute to external factors by which volume changes; water/binder ratio, materials composition, aggregates’ volume are internal factors.
Therefore, it is essential to control the cracking of AAC by identifying the factors affecting it, which is vital to the serviceability of AAC structures.

This study was conducted to determine the factors that may affect the compressive strength of fly ash-based geopolymer.
By looking at various factors that could potentially affect the compressive strength of geopolymer, this study intends to determine the contribution of these factors from the properties of the fly ash and the mixture composition.
Physical and chemical properties of the fly ash itself will greatly affect the results obtained.
Internal factors include the physical and chemical properties of fly ash.

The effect of chills on the microstructure and mechanical properties of CADI was investigated after Austempering.
The mechanical properties of the CADI samples (as-cast and austempered) were evaluated for hardness, impact and wear.
The mechanical properties of ductile irons are primarily due to their matrix structure which is based on the production process and its composition [3-4].
The cooling rate is an important factor which affects the hardness, especially when the metallic chills are placed at the bottom and side of the moulds [8].

The results indicated that the major factor affecting them was the temperature in stageⅡ(T2).
By introduce of microcell in fiber/polymer composites, fiber/microcellular polymer composites with high mechanical properties and light weight were obtained.
In stage Ⅲ, the high mechanical properties of the composites would be gained through further curing at the atmosphere pressure and room temperature (RT) for 14 days.
The results of orthogonal experiment showed that these factors affecting the impact strength from strongly to weakly are temperature in stageⅡ(T2), temperature in stageⅠ(T1) , holding pressure in stageⅡ(P2) and holding pressure in stageⅠ(P1), respectively.
These factors affecting the impact strength from strongly to weakly were temperature in stageⅡ(T2), temperature in stageⅠ(T1) , holding pressure in stageⅡ(P2) and holding pressure in stageⅠ(P1), respectively.

Aluminium alloys have very useful properties.
Their mechanical properties are mostly influenced by former mechanical and thermal treatment.
Thermal and mechanical treatments influenced the anelastic properties of the material.
