In this paper, metal flow lines of a forged crankshaft are visualized using a rigid-thermoviscoplastic finite element method with a versatile scheme of visualizing metal flow lines formed during shape rolling from bloom to round bar. The importance of metal flow lines is also emphasized in terms of product quality and structural integrity. The variation of metal flow lines on various cross-sections with the stroke is shown in detail, emphasizing the importance of useful visualization capability to conduct successful process design of complicated hot forging processes.
