前言到目前为止,适用于车辆各部的新金属材料的例子未必不多,但作为铁道的需要,在最近的高速化、节约经费、提高服务质量等的急要任务中开始对强度部件的金属新材料提出有更高要求,期待更迫切。在这里,其焦点集中于车体、轮轴和制动材料,这将涉及传统的材料动向和材料研究的方向。 Foreword So far, there are not many examples of new metallic materials that are suitable for the various parts of vehicles. However, as the demand for railways, new metal components for strength components have been started in recent tasks such as speeding up, cost saving and service improvement. Materials raised higher requirements, expectations more urgent. Here, its focus is on bodywork, axle and brake materials, which will address the traditional trends in materials and materials research.
