“…For example, it is known that mechanical values increase when ceramic-based reinforcing products are homogeneously present in the matrix [37]. In Mg metal, Al and/or Si reinforcement generally forms Mg 2 Si and Mg 17 Al 12 intermetallic in the structure of the composite material [12,[38][39][40]. These compounds give the whole structure different properties [12,38].…”

“…In Mg metal, Al and/or Si reinforcement generally forms Mg 2 Si and Mg 17 Al 12 intermetallic in the structure of the composite material [12,[38][39][40]. These compounds give the whole structure different properties [12,38]. Intermetallic compounds (specially Mg 2 Si) are preferred in phase type due to their high melting temperature [41], low density [42], high hardness [40] and low thermal expansion coefficient [43].…”

“…It is found in the literature that other elements added to Mg improve corrosion resistance and hardness values [11,12,34,38,40,[44][45][46][47][48][49][50][51]. However, the limited use of Pb addition is remarkable during the studies are examined.…”

“…However, the limited use of Pb addition is remarkable during the studies are examined. In our previous studies, it was found that different amounts of Pb (0.2%, 0.5%, and 1%) were added to Mg metal and phase ratios in the structure changed [12,34,38]. In addition, as is known, the use of heavy metals such as Pb has been limited by many international health organizations [52][53][54].…”

In this study, research has been made on the aging of metal matrix composite materials produced by the in situ casting system. Mg matrix composite material was produced by the in situ casting system. In this study, 90%Mg+10% Al 12 Si (wt) ingot casting was performed for alloy formation and 1% Pb was added as an alloying element to the melted structure. This study aims to examine the effect of the artificial aging (AA) process on hardness and microstructure after alloying and composite of Mg metal. The in situ casting system was used in the casting of Mg alloy under the Ar gas atmosphere. The material after required casting homogenization process; for the AA process, they were embedded in a powder graphite filled vessel and kept at 350°C for 1 h and then quenched (with 25°C water). Later; after quenching, the materials were kept at 150°C for 2, 4, 12, 16 and 24 h and aged samples were obtained. Microstructure images were obtained from the samples by scanning electron microscope (SEM) and light optical microscope (LOM) and then the hardness values of the micro hardness device were measured. Grain structure because of AA heat treatment; showed changes according to un-aging material. The hardness value is directly proportional to the increasing aging time of the materials applied to the AA process; it was found that the levels increased approximately to 45% (86HV to 125HV) compared to the un-aging material and passed to the fixing phase.

“…However, too high corrosion rate in aggressive environments has limited the application of Mg alloys in automotive industry [3][4][5][6][7]. In answer to this, coating technology has been considered to be an effective means of controlling and reducing corrosion rates, such as organic coatings [2], microarc oxidation (MAO) [8], high velocity oxy-fuel thermal spray [9] and physical vapor deposition [10].…”
