| Abstract | The firing process to bond an enamel frit onto a steel substrate is conducted under a high-temperature condition of approximately 830°ýC for 3min, which leads to the thermal deformation of the enameled steel product. This thermal deformation of the enameled steel is one of the main problems with the firing process. The thermal deformation is also affected by the residual stress of the enamel coating, which is generated by the mismatch between the thermal expansion coefficient of the enamel and that of the steel substrate. The objective of this study was to predict the deformation and residual stress of enameled steel using an analytical model and finite element analysis. To verify the results from the prediction methods, firing and cooling experiments were performed using the same conditions as such methods, and the experimental results were compared to those of the prediction methods. The residual stress was measured using a crack indentation technique based on a pyramidal diamond indenter. The magnitude of the residual stress could be determined by comparing the crack lengths in the unstressed and stressed specimens. The results of the prediction methods were in good agreement with the experimental results with respect to the deformation and residual stress. |

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.
