Two types of tensile bars were observed in this study of golf iron heads for TaylorMade Golf. As-cast and as-cast then machined tensile bars. The tensile bars underwent tensile tests to observe tensile strength, percent elongation, and fracture mechanisms. Furthermore, the hardness of the tensile bars was also taken despite seeing no difference in sample types. However, the as-cast samples did not consistently meet the requirements of percent elongation > 10.00% as there was a sample with 0.00% and another with 1.26%. These samples also showed brittle fracture, instead of the desired cup-and- cone ductile fracture. To investigate further, transverse sections …
