| Abstract | Compaction of pure B$_{4}$C and Ni$_{2}$B nanolayer coated B$_{4}$C was studied using uniaxial die compaction and combustion driven compaction techniques. Effects of different compaction techniques and the Ni$_{2}$B nanolayer around B$_{4}$C particle surfaces on green B$_{4}$C sample characteristics are the focus of this study. The combustion driven compaction process yields much higher green density and strength than the uniaxial die compaction process. For the samples obtained from the same compaction technique, the Ni$_{2}$B nanolayer on individual B$_{4}$C particle surfaces improves the green density and strength of the B$_{4}$C powder compacts. For the combustion driven compaction process, optical images show micro-cracks on the surface of pure B$_{4}$C compact while crack-free surface is observed for Ni$_{2}$B nanolayer coated B$_{4}$C sample. Scanning electron microscopy analysis shows the same trend as the green density and strength measurements. Combustion driven compaction diagram for hard and brittle materials such as B$_{4}$C is discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
