Study of Formability of Brass Sheet Metal Under Different Temperature Conditions

Abstract

In the present work focus devoted to the results obtained from uniaxial tensile test were utilized to analyze flow stress behavior of brass under different orientation, temperature and strain rate conditions and the study of forming limit diagrams for stretch forming of brass sheet material at room temperature and at various elevated temperatures have been estimated experimentally by performing stretch forming operations using warm forming tooling setup (i.e., suitable punch – die and blank holding set-up). After stretch forming the brass sheets metal at different temperature conditions (i.e., 300 K to 773 K) the minor and major strains are measured by using the electron microscope and then forming limit diagrams (FLDs) were constructed. With the help of forming limit diagram (FLDs) formability of brass analyzed. These formability limit diagrams (FLDs) were co-related with mechanical properties such as tensile strength and % elongation, and in-plane anisotropy of the brass sheet material.
