A presence of irregular intermetallic particles of Al(FeMn)Si phase, undissolved Mg2Si particles and fine Mn-rich dispersive particles was observed in the initial state's microstructure.
The role of Mn-rich dispersoids was to prevent the solid solution grains growth of Al-based alloy [15].

Aluminum (Al) alloys are the most widely used in the high strength to weight ratio.
Thamizhmanii et al [6] discussed the effect of burnishing parameters on surface finish and surface hardness.
Al composite also got a little attention as a material can be finished by burnishing.

and for e > eL, (3) From the equations above, one can clearly see that if the the initial tangent modulus Eit and the strain at peak stress e0 are known for a given concrete compressive strength fc¢, the complete stress-strain curve for unconfined HSC under uniaxial compression can be obtained.

Recent experimental data of normal weight concrete reported by Wee et al.[9], Mansur et al.[11], Zhang and Wu [12] and Iravani [6] is listed in Table 2.
Table 2 reveals the following: (1) Generally, CEB-FIP [1], Wee et al. [9] and ACI [10] overestimate the elastic modulus of HSC when compared with the test data; (2) NS3473 [8], Iravani [6] and Rashid et al. [2] give lower predictions than the experimental results; (3) An improved empirical model for predicting the elastic modulus becomes necessary and possible.
(4) where is taking the same values shown in Table 1 as those proposed by Rashid et al.[2].

According to EL-Safaty et al.[13] the more appropriate modulus of elasticity of a composite is the one which most closely approximates to the dentine so that tensions in the biologic structures do not occur.

Review: Effect of Alloying Element on Al-Si Alloys M.N.
Introduction Al-Si cast alloys contribute to 85-90 % of aluminium (Al) casting products.
Fe is a deleterious impurity presence in Al-Si alloys as it dissolves readily in Al and forms brittle intermetallics.
In Al-Si9 Cu X series, increasing Cu level (from 0 to 4 wt. %) in Al-Si9 Cu X series leads to increasing YS and hardness.
Seifeddine et al. [4] noted that the strength of the Mn added Al- 9% Si increases gradually with an expense on ductility.

In this paper, the fitness function is defines as one summary for add up errors El in some location of SSDA.
Take reverse El for -El to fit the condition of get the maximum value in the fitness function, see the equation as below: (1) E evolutionary operators Computation formula for crossover rate Pc and mutation rate Pm in evolutionary operators is as follows: (2) (3) To get the better results, the parameter values therein are taken on the basis of several experimental results as: Pc1 =0.9, Pc2 =0.6, Pm1 =0.1, Pm2 =0.001.
