| Abstract | The microstructural evolution and grain refining efficiency of sub-rapidly solidified (SRS) Al-10Ti master alloy has been studied. The results show that the mean size of Al$_{3}$Ti particles in the SRS Al-10Ti master alloy decreased significantly and the morphology changed from strip-like to blocky and short rod-like compared with the conventional Al-10Ti master alloy. Grain refining experiments show that the SRS Al-10Ti master alloy is more effective than the conventional master alloy for refining Al-7Si alloy. The conversion rate of columnar to fine equiaxed grain structure in the Al-7Si alloy was promoted by the addition of SRS master alloy, and the microhardness of Al-7Si alloy increased. The mechanisms of grain refinement of aluminum by inoculation with improved Al-10Ti master alloy are discussed based on the solute theory. The decrease in size, increase in quantity, and change in morphology of Al$_{3}$Ti particles are considered as the reasons for the improvement of microstructure and microhardness. |

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.
