Microstructural studies of A357 alloy cast by RSF process

Abstract We studied rheocasting of an A357 (Al-7Si-0.6Mg) alloy using the Rapid Slurry Formation (RSF) technology developed by Rheometal. The technology is based on a so-called solid enthalpy exchange material (EEM). Semi-solid slurries of A357 with around 30% solid fraction were produced in this way. The slurry formation was modified by adding several grain refiners (Al-5Ti-1B, Al-3Ti-0.15C and Si-1B master alloys) individually. Stirring speed was varied to study its effect on microstructure. The slurry so produced was air cooled and quenched in water. It was observed that rapid heat extraction, nucleation and forced shearing action developed globular α-Al phase.

About National Digital Library of India (NDLI)
NDLI logo

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.
