We have developed the cold working technology that can form a collar or a boss in a round bar of mild steel bar of 8, 10, 12 and 25mm in diameter by repeating alternate bending stress of tension and compression to the bar subjected to axial compressive stress of suitable magnitude slightly lower than yielding stress at room temperature. By this technology using Bauschinger effect due to alternate bending stress of tension and compression, large compressive deformation can occur to form a collar or a boss in a round bar. Moreover, temperature-rise in the collar-forming process is below 15℃ and without giving the mechanical damage such as micro-crack initiations and strength degradation.
