“…Dhanabalan et al [23] analysed electrical discharge machining process on the form tolerances and the results direct that while expanding the pulse on time, the value of circularity, cylindricity and perpendicularity decreased up to 350 µs and then increased with expanding the pulse on time. Sweety Mahanta et al [16] investigated that the SR and MRR values increase with a hike in the peak current and pulse on time; moreover, wider and deeper crater was observed due to high melting and vaporization of the material.…”

A generous development of electrical discharge machining method has been stimulated in the province of metal matrix composites materials. In this extant work, the optimal condition for various output responses specifically circularity, cylindricity, perpendicularity and radial over cut are exposed by employing grey relational analysis procedure by optimizing the input process parameters alike pulse on time (T on), peak current (I) and gap voltage (V). The Hybrid Metal Matrix Composite material is evolved by handling the stir casting approach and then machined by exploring the input parameters using L 27 orthogonal array. From the consequences of grey relational grade, a response table was discovered to elect the optimal conditions of the individual parameter. The most contributing input parameter is current with 69.08%, which is determined from the ANOVA table. Finally, the optimal conditions which were acquired from the response table are peak current of 12 A, pulse on time of 50 µs and gap voltage of 30 V and also verified through an authentication test which illustrated that optimal process parameters are competently improved by 0.1452 when compared to the predicted parameter. The machined surface is analysed using a scanning electron microscope. The results palpated that the peak current increases the number of microvoids and size of the crater was increased and the poor surface finish was achieved.

“…To obtain a maximum tensile property of composite made of Al2014 is recommended to use 6% boron carbide and 8% coppercoated basalt fibre. The literature confirms that the use of hybridization is likely to enhance the mechanical and wear properties of the composites and form a new class of composites that can replace bulk materials used in the production of components with higher strength and lighter weight [19].…”

The use of boron carbide-reinforced aluminium matrix composites has grown rapidly in critical applications of aerospace industries, automotive sectors, military, and nuclear engineering. However, boron carbide reinforcement within AA6061 alloy is worthy of investigation in terms of its mechanical and tribological properties. Novel aluminium matrix composites were developed with three different reinforcements (i.e. 5, 10, and 15 wt% of B 4 C) by using the stir casting process. The developed samples were then tested for performance in terms of mechanical properties (i.e. tensile strength, bending strength, impact strength, shear properties, and micro-hardness). The microstructure of the developed samples was analysed using a scanning electron microscope. By adding 5% B 4 C reinforcement, the samples display enhanced mechanical properties (high bending, increased resistance to impact test, and shear strength). The micro-hardness tends to increase by increasing the percentage of reinforcement. The novel composites have superior wear resistance due to an increase in the content of B 4 C particles. The measurements indicate that the wear rate resistance is significantly higher for the composite material with a large amount of B 4 C particles when was compared with AA6061 alloy. The patterns of surface analysis reveal a homogeneous distribution of ceramic reinforcements in 5 and 15 wt% of B 4 C samples, as well as a low agglomeration of embedded particles.

“…Al 7075 alloy reinforced with 1.5 wt% B 4 C and 1.5 wt% fly ash nanoparticles hybrid composites was being considered for machining through EDM process. The surface characteristics observations revealed that high input energy melts more sufficient material with greater crater generating coarser surface texture [17]. A new combination of fabricated hybrid metal matrix composite of A359 with 2.5 wt% B 4 C and 2.5 wt% Al 2 O 3 is being made up in-house by electromagnetic stir casting.…”

In this paper, aluminium alloy metal matrix composites were manufactured via stir cum squeeze casting technique owing to their tremendous automotive and aviation applications. The aluminium alloy with 12 weight percentage boron carbide (A413 with 12 wt% B 4 C) composites was prepared with optimal stir cum squeeze casting parameters like applied squeeze pressure of 140 MPa, 225 °C preheated die temperature and 12 wt% of B 4 C particles which yielded pore-free fine-grained equally distributed ceramic particles of the composite, leading to an enhanced higher hardness of 136 VHN and higher tensile value of 373 MPa due to squeezing pressure and B 4 C particles. The prime intern of the wire electrical discharge machining process was adopted for investigating the machinability of stir cum squeeze cast high-strength A413 with 12 wt% B 4 C composite. The stratagem of response surface methodology along through central composite rotatable design was taken towards systematic design of experiments. The experimental study results exhibited a possibility of higher amount of metal removal rate for maximum pulse on-time and peak current values, and also better surface roughness was acquired for higher values of pulse off time. The mathematical model shows excellent prediction in accordance with experimental data which seems to fall inside the bounds of acceptable average error around 6.47% and 1.52% for metal removal rate and surface roughness through additivity tests, respectively. The proposed multiresponse optimization results revealed a great potential for improving machined surface quality which could be utilized according to the industrial requirements.
