“…One important aspect to consider under hybrid composites is the use of reinforcement with bimodal or trimodal particle size distributions. It has been reported that large sized ceramics are more capable of producing grain refinement compared to smaller ceramics, while finer particles provide a higher number of barriers per unit volume compared to composites reinforced with larger particles at the same weight percentage 92,93 …”

The use of metal matrix composites (MMCs) in a variety of products is significantly increasing with time due to the fact that their properties can be tailored and designed to suit specific applications. However, the future usage of MMC products is very much dependent on their beneficial aspects and hence it is critical to ensure in a robust repeatable manner the superior physical property advantages compared to conventional unreinforced monolithic metal counterparts. Although numerous routes are available for production of MMC products, each of them has their own advantages and disadvantages. This article provides an overview of advanced production routes for MMCs. The discussion also highlights challenges and presents a future prospectus for MMCs. Powder metallurgy and casting routes are still extensively used for production of MMCs. Aluminum alloys are today the most commonly used matrix materials in MMC products.Carbides (eg, SiC, TiC, and B 4 C), carbon allotropes (eg, CNTs and graphene), and alumina (Al 2 O 3) are currently the most used reinforcement materials. Nevertheless, the use of nano and of hybrid reinforcements are seeing increased usage in niche applications. Additive manufacturing (AM) is discussed as a novel production route for MMC products. This process represents a promising method for the production of MMC products.

“…Ayrıca, haddeleme işleminin AlMg3/SiCp kompozit malzemelerin çekme dayanımı, akma dayanımı, sertlik gibi mekanik özelliklerini arttırdığı halde çentik darbe dayanımını düşürdüğü gözlenmiştir. Cerit [37], toz metalürjisi üretim yöntemini kullanarak yapmış olduğu çalışmada tek ve çift parçacık boyutlu SiC partiküllerinin Al 2124 alaşım matrisli kompozitlerin darbe davranışı üzerindeki etkisini incelemiştir.

Kompozit malzemeler endüstriyel uygulamalarda ani yüklenme, darbe, düşme ve çarpma gibi dinamik etkilere maruz kalabilmektedir. Bu tür etkiler tasarımda kullanılan malzemelerde gözle görülen hasara ya da görülemeyen iç hatalara sebep olmaktadır. Yapılan literatür taramaları, partikül takviyeli metal matrisli kompozitlerin darbe davranışının incelendiği çalışmaların sınırlı sayıda olduğunu göstermektedir. Gerçekleştirilen bu çalışmada, mevcut duruma dikkat çekmek istenilmiş olup konu hakkında genel bilgiler verilmiş ve son olarak da gerçekleştirilen çalışmalar özetlenmiştir. Buna göre, yapılan çalışmalarda genel olarak sıcaklığın, takviye partikül tipinin, hacim oranı ve boyutunun, ısıl işlemin ve ikincil mekanik işlemler gibi üretim parametrelerinin partikül takviyeli kompozit malzemelerin darbe dayanımına etkileri araştırılmıştır. Yapılan çalışmaların literatür açısından henüz yeterli düzeyde olmadığı tespit edilmiştir. Dolayısıyla, birçok alanda ve çok önemli uygulamalarda dinamik yükleme şartları altında kullanılan partikül takviyeli metal matrisli kompozitlerin darbe davranışları üzerine daha fazla çalışma yapılması gerektiği sonucuna varılmıştır.

“…They have found that larger particles produced more grain refinement than smaller ones and that the yield strength of the bimodal reinforced AZ91-SiC composite was higher than that of the single-sized particle reinforced composites. Cerit 54 investigated the low-speed impact behavior of aluminum matrix composites reinforced with bimodal SiC particles, fabricated via a powder metallurgy route. It was reported from this work that while the dual particle size composite could provide improved hardness and impact performance compared to a single particle size composite, agglomeration of the finer reinforcement may have had a negative effect on its hardness and impact behavior.…”

Three arrangements of reinforced A356-based composites were fabricated. Samples with 3 wt% Al 2 O 3 (average particle size: 170 mm), 3 wt% SiC (average particle size: 15 mm), and 3 wt% of mixed Al 2 O 3 -SiC powders (each reinforcement 1.5 wt%) were fabricated. The novel fabrication process of two-step stir casting followed by rolling was utilized. Analysis of the effect of using bimodal-sized ceramic particles and process parameters on the microstructure and mechanical properties of the composites was examined. Electroless deposition of nickel was used to improve the wettability of the ceramic reinforcements by the molten metal. From microstructural characterization, it was found that fine SiC particles were agglomerated, including when coated with Ni-P. It was also revealed that the rolling process broke the fine silicon platelets within the A356 matrix, which were mostly observed around the Al 2 O 3 particles. The processed microstructure of the composite was altered in comparison to conventionally cast A356 MMC by translocation of the fractured silicon particles, by improving the distribution of fine SiC particles, and by elimination of porosities remaining after casting. A good bonding quality at matrix-ceramic interface was formed during casting and no significant improvement was found in this regard after the rolling process. The mechanical properties of the composites tested showed that the samples, which contained the bimodal ceramic particle distribution of coarse Al 2 O 3 and fine SiC particles produced the highest levels of composite strength and hardness.
