Powder Metallurgy Processing and Mechanical Characterization of Iron-Based Composite Reinforced with Alumina and Zirconium Diboride Bhupendra Prakash Sharma, G. S. Rao and Umesh Kumar Vates Abstract In the present manufacturing scenario, iron-based metal matrix compos- ites are the key requirement for heavy vehicle and structural applications. But, due to the problem of rapid oxidation during the development of iron-based composites, this field is only limited up to few research level. In the present research work, an easy formation of iron-based metal matrix composite materials are proposed through powder metallurgy process with different mass fractions of zirconium diboride and alumina reinforcement such as 5% Al 2 O 3 –10% ZrB 2 , 5% Al 2 O 3 –5% ZrB 2 , and 10% Al 2 O 3 –10% ZrB 2, all in the form of atomized particles. Further, microstructural read- ings on cross section as well as surface of the bar and hardness measurements were attained and investigated. Improved hardness and tensile strength are noted from newly developed performs.

Many researchers are striving to develop the metal matrix nanocompos- ites by using the most suitable fabrication methodology as powder metallurgy (PM) stir casting techniques and techniques [1]. The ferrous-based PM-processed struc- tural parts have already been taken over by the automotive and off-highway vehicle applications due to the fulfillment of desired characteristics of materials from PM process. It is clear that alloy steels are suitable material for various applications such as power plants, aircraft, marine industries, and bearing manufacturing units [2]. B. P. Sharma (B ) · G. S. Rao · U.
