History Of

Titanium and its alloys have evolved faster than any structural material in the history of metallurgy. The increasing employment of titanium in many different applications is mainly due to its light weight, high strength and structural efficiency. The titanium metal matrix composites (Ti-MMCs) have helped to achieve these objectives. The aim of this work is the development and study of Ti-MMCs manufactured via hot pressing at 900 °C reinforced by sub-micron and micron boron carbide (B4C), amorphous boron and sub-micron and micron titanium diboride (TiB2) particles in order to improve its mechanical properties. Full dense composites were obtained with this consolidation technique. The influence of the different reinforcements has been analyzed. Moreover, the strengthening effect of sub-micron reinforcements is compared to the effect of the material with the same chemical composition in a micro-scaled phase. Comparison has been established studying the microstructure (grain size and density) and mechanical properties through tensile and hardness tests.

Now a day’s Hybrid Metal Matrix composites has a large number of applications in automobiles, aircrafts and structural applications like brake rotors, engine parts and cylinder liners. The aim of this study is to determine the mechanical properties of boron carbide (B4C) and zirconium silicate (ZrSiO4) particulate reinforced with AA6063 alloy composites. In this experimental study, B4C and ZrSiO4 particulates reinforced with AA6063 composites were manufactured by stir casting technique. Mechanical properties of these composite materials were investigated by different weight percentages, 3%, 6%, 9% of boron carbide (B4C) and 9%, 6%, 3% of zirconium silicate (ZrSiO4) respectively. The mechanical properties evaluation reveals variations in hardness and the tensile strength values with the composite combinations investigated in this work. From the experimental studies, the optimum volume fraction of hybrid reinforcement in AA6063 alloy on the basis of mechanical properties and SEM analysis is also determined.

The excellent mechanical properties of Aluminium Metal Matrix Composites find applications in a variety of engineering applications in the automotive, aerospace and heavy machinery industries. This study aims at synthesis and characterization of Al 64430 reinforced with SiC particles and Rice Husk Ash (RHA). Rice husk ash is an agricultural waste which is produced in millions of tons worldwide. Aluminium was used as the base metal. With liquid metallurgy technique the metal matrix composites were prepared. The MMCs were synthesized with 3 % weight percentage RHA in Al metal matrix and the mechanical properties such as hardness, tensile strength and structural properties of MMCs were studied. The microstructure of the synthesized composites was examined by optical emission microscope and XRD. The Vicker’s microhardness test was performed on the composite specimens from base of the cast. The synthesized MMCs were found to have increased tensile strength, hardness, increased ultimate strength. The density of MMCs was observed to be decreased. This study indicates that RHA can be used as reinforcement material to synthesize light weight composites with increased hardness, tensile strength, Young’s modulus for various industrial applications.

A hybrid Al7075 metal matrix composites have been fabricated through liquid metallurgy route (Stir Casting method) using Al2O3 and B4C as reinforcement materials. The effect of weight percentage of reinforcement materials on mechanical properties of the composites have been studied by varying the weight percentage of Al2O3 as 3, 6, 9, 12 and 15% while keeping constant weight percentage of B4C (3%). The as-cast microstructure, tensile strength, micro and macro hardness of the fabricated hybrid composites have been studied. The mechanical properties of the prepared composites were increased with increasing the weight percentage of the reinforcement in the composite. The maximum tensile strength, micro-hardness and macro-hardness of 309 MPa, 140 VHN, and 112 BHN, respectively, were obtained for a hybrid Al7075 matrix composite containing 15% Al2O3 and 3% B4C.
