“…Variation of hardness as a function of temperature of aging and duration for the above composites are depicted in figures 15-20. Hardness is found to increase gradually with time for both the DA and its composites. It reaches peak hardness value followed by over-aging that results in decrease of hardness [16]. The hardness increases with increase in amount of mild steel particulates.…”

In the present study Duralumin(DA) based Mild Steel particles (MSp -6% wt. and 12% wt.) reinforced composite are fabricated by cold compacting the milled powders. The mechanically mixed powders are compacted in a die cavity by applying a uniaxial steady load in the range 22-38 T. The hardness of green compacts produced are increased by sintering. The SEM images showed an even dispersion of MS p in the duralumin alloy and elemental composition is confirmed by the EDAX spectrum. The sintered specimens were further subjected to aging treatment. Compacts were soaked at 550 0 C for a span of 2 h and then are quenched in water at ambient temperature. The temperatures selected for aging treatment are 100, 150, and 200 0 C and hardness was checked for every 60 minutes of time. The peak hardness obtained because of aging heat treatment is found to be much better than the corresponding sintered compacts. Compacts peak aged at 100 0 C exhibited better tensile strength than the rest of the other specimens. Impact Factor (JCC): 7.6197 SCOPUS Indexed Journal NAAS Rating: 3.11quantity of reinforcement can be dispersed in the matrix and also a better control of microstructure phases is achievable [5]. Also in specific by aluminum PM it is possible to produce high performance, net or nearly net to shapes of components, hence bringing down or avoiding the investment and running costs attached with complex machining operations [6]. In the recent year's researchers have used ceramic particles for producing the composites. But the major drawback with ceramics reinforced MMC's are their relatively lower toughness and toughness. Also, the relatively higher costs would make them economically unsuitable for various applications. In contrast, steels are competitively low cost, which has made them attractive in a wide range of applications [7].In the light of above, the present investigation concentrates on to develop the composite by dispersing the mild steel particles in different proportions in duralumin matrix by employing the cold compacting approach. The composite developed is expected to provide superior mechanical properties suitable for high strength, heat and wear resistant applications.

Öz: Bu çalışmada, yanıt yüzey yöntemi (YYY) ve genetik algoritma kullanılarak tufal ilaveli harçların basınç dayanımının optimizasyonu yapıldı. Deney serilerinin belirlenmesinde ve deneysel verilerin analizinde YYY kullanıldı. Farklı oranlarda tufal içeren 25 seri harç numunesi hazırlandı ve bunların basınç dayanımları belirlendi. Yanıt yüzey yöntemi ile deneysel verilerin analizleri yapılarak matematiksel bir model oluşturuldu. Genetik algoritma kullanılarak bu modelin optimizasyonu yapıldı ve optimum parametre değerleri belirlendi. Optimizasyon sonucu ile kıyaslamak için doğrulama deneyi yapıldı ve % 90'nın üstünde korelasyon olduğu gözlendi. Bu çalışma sonucunda, YYY ve genetik algoritmanın birlikte kullanılarak daha az deney ile güvenilir optimizasyon yapılabileceği görüldü.Abstract: In this study, compressive strength of mortar specimens containing steel scale was optimized by using response surface method (RSM) and genetic algorithm. RSM was used in the determination the experiment series and analysis of experimental data. 25 series mortar samples containing different ratios steel scale were prepared and the compressive strength of these series was determined. A mathematical model was created by analyzing the experimental data with response surface method. This model was optimized by using genetic algorithm and optimum parameter values were determined. Confirmation test was done to compare with the optimization result and it was observed that the correlation was over 90%. As a result of this study, it was observed that it could to make reliable optimization with less experiment by using of combination of RSM and genetic algorithm.

“…The advantageous characteristics of ceramic materials include low density, high abrasive toughness, hardness, and rigidity. Nevertheless, monolithic ceramics main drawback is their low fracture toughness [11,8,2,7]. Thence, many studies have been conducted with the aim of addressing this shortcoming [8,1,2,3,9,10,13].…”
