The objective of this research is to experimentally investigate the metallurgical, mechanical, and tribological behavior of [Formula: see text], SiC, and [Formula: see text] reinforced AZ31 magnesium metal matrix composite (MMC) fabricated via powder metallurgy process. Accordingly, the mixing of the powders was carried out through ball milling operation at various times with constant speeds. The compaction of the milled powder was carried out on hydraulic press at various compaction pressures. The improvement of the wear resistance performance at 10 and 5 vol.% SiC were revealed around 12.9% and 25.8%. The fracture mechanisms of the optimal specimen resulting from the compression test were studied under SEM observation and it revealed that both ductile and brittle fractures occurred. The results from the confirmation test revealed an improvement of 2.04 g/cm3, 13%, 110.35 MPa, and 1293.399 MPa for actual density, porosity, ultimate strength, and hardness, respectively. The uniform nature of particle distribution was observed in SEM micrograph under investigation of the microstructure of the sample. The average particle size of the sample was also obtained around 809.14 nm. The proposed material is expected to be useful for various automotive and aerospace applications precisely for pistons and wings of airplane in aerospace.

“…Various methods are used to manufacture aluminum and its alloys. However, when several factors such as production cost, energy, time and occupational health and safety factors are taken into account, it has been observed that powder metallurgy (P/M) offers greater advantages compared to other conventional manufacturing methods [6,7]. P/M is the technique of manufacturing materials difficult to be manufactured using materials in powder form with a minimum level of tolerance.…”

Addressing the need for light materials in today's industry, the present study aims to analyze the effects of sintering parameters on pure Al material manufactured using powder metallurgy technique. 99% pure and commercially obtained Al powder at a dimension of 180 µm was subjected to pre-heating and placed in a specially designed die. Al powder was compacted into a die using an upper punch with 500 MPa pressure and later removed from conical die for the sintering process. In order to find the optimal sintering temperature and duration, the compacted samples were sintered separately at 500 o C, 550 o C and 600 o C for 45, 60 and 75 minutes for each temperature value. Microstructural analysis, microhardness test and density test of each sample obtained from the sintering process were performed to determine the most optimal sintering durations at a given temperature, and changes caused during these processes were observed. As a result of examinations, it was determined that the optimal sintering temperature and time was 500 o C/60min, 550 o C/45min, 600 o C/45min. Finally, the samples obtained in different sintering durations for three different temperatures were subjected to a tensile test. According to the tensile test result s, it was determined that the most suitable sintering parameter for pure Al was 600 o C/45min.
