Review on ferrous and non-ferrous casting defects and their analysis

Abstract

The castings can be produced by using sand moulds and permanent dies. The rejection rate is more in sand casting process due to more number of process parameters. The papers reviewed about the defects occurred in the most widely used ferrous and non-ferrous materials such as cast iron, steel and aluminum are referred for this work. The defects are analyzed using various types of experiments, optimization techniques and software. This paper is useful to researchers and industrial persons to know about the tools available to analyze the defects and remedial action can be taken for the defects.The castings can be produced by using sand moulds and permanent dies.
