Improving the strength and other properties of Automobile components like Gears, Brake rotor discs, Pistons etc., are very much needed. Which are made up of Al-SiC particles Metal Matrix Composites (AMMCs) via centrifugal casting offers high wear resistance at outer periphery and good toughness at inner core by gradient distribution of SiC in Al-matrix. The rich concentration of SiC at outer region is prone to the corrosion phenomena in the components employed in corrosion environments. It is due to the chemical heterogeneity caused by SiC and the intensity of corrosion attack accelerates with increase of SiC particle concentration. The wear resistance and corrosion resistance of the above said automobile components can be greatly enhanced by severe plastic deformation (SPD) is demanded, which resulting in a high defect density and equiaxed nanocrystalline (NC) structure (d

Due to an increased consumption of fossil fuel and rise in the cost of diesel and petroleum products, developing nations such as India, Sri Lanka and Bangladesh have been focusing on alternative energy resources such as the production of biodiesel from biomass or related wastes. The biodiesel can be generated from dedicated energy crops such as Karanja and Jatropha. Biomass can be used for energy, fuels and chemicals production has generated significant concerns across the globe, especially in developing nations, due to the shortage of food and cultivable land and extremely high population density. This has led to the use of non-edible biomass resources such as Karanja, Jatropha, Neem, Mahua, and Sorghum. The current book focuses on the thermochemical conversion process called pyrolysis. The pyrolysis is one of the most promising methods to produce bio-oil, bio-char and gases, from the thermal degradation of biomass in an inert atmosphere. The present study has utilized with different de-oiled seed cake generated from variety of biomass. The focus of the research work is pyrolysis of press seed cake produced from lignocellulosic biomass regardless of the type of original plant source was carried out in a fixed bed batch reactor to study the effects of temperature, retention time, and nitrogen (N2) flow rate on bio-oil and bio-char yields. In this book Response surface methodology based on Box-Behnken design was used to determine the optimum operating conditions to maximize the bio-oil and bio-char yield. The results obtained from the current study have made a significant contribution in demonstrating the value addition to various seed cake from dedicated energy crops.
