本文报道了JIS A5083铝合金齿条的快速搅拌成形。在齿轮齿条式模具上放置料盘，对其背面进行摩擦搅拌。由于摩擦搅拌产生的高压和热量，材料变形并精确填充模具的精细型腔。本研究探讨成形条件及结果，包括材料填充率在齿。认为材料的变形量是影响填充率的关键因素，单道次加工中的刀具台肩直径或多道次加工中的路径面积也会影响填充率。
Friction-stir-forming (FSF) of gear-racks of JIS A5083 aluminum alloy is reported in this paper. We put a material plate on a gear-rack die and conducted friction stirring on its back surface. The material deformed and precisely filled the fine cavity of the die due to high pressure and heat caused by friction stirring. This study investigates the forming conditions and the corresponding results, including the material fill ratio in the tooth. It is thought that the deformation volume of the material is key for the fill ratio, and the shoulder diameter of the tool in a single-pass process or the path area in a multi-pass process affects it as well.
