The aim of this present study is to develop aluminum reinforced SiC- TiC hybrid metal matrix composites by liquid stir casting process. It also investigates the effect of hybrid ceramic reinforcements on the microstructural, mechanical and tribological behavior of composites. In present study, for composites SiC content is fixed as 1 wt% and TiC content is varied as (1, 1.5, 2 and 2.5 wt%). It is found that increase in the reinforcement content of SiC-TiC particles increases the hardness and decreases the density of composites. Improvement in wear resistance is also seen at higher reinforce- ment content. It is expected that this composite is beneficial in the development of lightweight compos- ites for aerospace applications. Ó 2019 Elsevier Ltd. All rights reserved.

Introduction In the last few decades, composite materials have been playing an important role in the development of many industries and engi- neering applications [1]. In past few years, materials have been used in transport, construction, communication and other engi- neering applications which are fulfilling the human needs [2]. Materials play a vital role in our daily needs and also in the devel- opment of any nation [3]. At present, the way in which materials are being used for the development of our daily needs is fairly enough to know the importance of engineering in our life [4]. With the rapid changes in manufacturing scenario among global indus- tries, new forms of materials are to be developed [5]. The newly developed material has better properties than traditional materi- als. All these necessities can be fulfilled by composites [6]. Later- ally, it has become popular because of its excellent properties (i.e., low density, light weight) and wide applications [7]. It is kind of advanced engineered materials; which have become mandatory for automobile as well as aerospace industries and have also shown a profitable business by itself [8]. They are also being used in various industrials product and shipbuilding, new edge cutting tools [9]. The reinforcement of this engineered advance materials gets diapered into the matrix either in a continuous or discontinu- ous phase [10]. Composite materials are extensively used in journal bearing, cutting tools and variety of interior design compo- nent and other parts [11]. In, the past few decades, major research area was the development of harder as well as lightweight com- posites materials which is applicable in aircraft and automotive industries [12]. Among all aluminum matrix composites has gained popularity due to diversified properties. In aluminum metal matrix composite the mostly used reinforcement are Al 2 O 3 [13], SiC [14], B 4 C [15], TiC [16], Graphite [17] and Carbon nanotubes [18]. In past studies it is reported that properties of aluminum matrix compos- ites depends on the amount of reinforcement (wt.%), grain size, shape and processing techniques [19]. Aluminum matrix compos- ites exhibit good strength and lower density than pure aluminum and its alloys. Aluminum matrix composite can be fabricated by powder metallurgy [20], infiltration processes [21], stir casting [22] and squeeze casting [23]. These manufacturing processes are divided into two categories. One is known as solid-state processing https://doi.org/10.1016/j.matpr.2019.08.186 2214-7853/Ó 2019 Elsevier Ltd. All rights reserved.
