Effect of Sicp on the Microstructure and Mechanical Properties of Sintered Distaloy DC Composites

Microstructure and properties of sintered metal matrix composites reinforced with SIC particles

“…They have found wide use in various engineering applications, especially for aerospace, automotive, wear and cutting applications [1][2][3][4][5][6][7][8][9]. This is due to good mechanical properties as well as the combination of special properties with ease of fabrication [1,3,7,10].…”

“…Particle-reinforced MMCs can be produced by both solid state (powder metallurgy technology) [1,2,4,5,10,11,14,15,[17][18][19][20][21] and liquid phase techniques (stir casting) [3,8,12,13,16]. It should be pointed out that powder metallurgy technology ensures some advantages, namely: lower energy consumption, higher raw material savings, near net-shape or net-shape parts fabrication, part dimensional accuracy, lower cost, simpler equipment for processing and shorter processing times and of course higher composition uniform distribution and a wide range of composition selection for the metal matrix, which is important in the case of production of MMCs [1,[17][18][19][20].…”

“…In these MMCs, iron [17][18][19], low-alloyed steels [1,2,14], tool steels as well as stainless steels [7,15,[21][22][23] [7]. Furthermore these materials are easy to fabricate and costs are not high.…”

“…Al/Al alloy -SiC [1, 3-6, 8-13, 16], Fe -SiC [17][18][19] as well as steel -SiC [1,2,7,14,15,[20][21][22][23] composites should be primarily listed. It is known that silicon carbide possesses high hardness and good wear resistance, high strength, good thermal characteristics and also resistance to oxidation at high temperatures and a very attractive cost [1,8,15].…”

“…It turns out that low and medium alloyed steels are also good candidates for matrix of MMCs (especially with wear properties) [14,25,26]. But thus far there have only been very few papers relating to these particulate-reinforced MMCs [1,2,14].…”
