机械工业的发展与材料科学的进展有密切的联系,或者说材料科学是机械工业发展的一个重要支柱。就像当年高速钢及硬质合金的发现,有力地推动了机械加工的进展一样。反之,机械工业的各个领域的进展又对材料提出了各种各样性能(或功能)的要求,促进了材料科学的发展。为了要降低机械装备的自重,就要发展高比强度的材料;要延长机器寿命,就要提高材料的疲劳强度、抗腐蚀或耐磨损的能力;为了实现能量的
The development of machinery industry is closely linked with the progress of material science, or material science is an important pillar for the development of machinery industry. Just as the discovery of high-speed steels and cemented carbides at that time strongly promoted the progress of machining. Conversely, advances in all areas of the machinery industry in turn put forward a variety of performance (or function) requirements for materials that have contributed to the development of materials science. In order to reduce the weight of machinery and equipment, it is necessary to develop high strength materials; to extend the life of the machine, it is necessary to improve the material fatigue strength, corrosion resistance or wear resistance; in order to achieve energy
