一概要据日本《省力与自动化》杂志报导(1985年12月号),日本工业技术院名古屋工业技术试验所陶瓷评价技术研究小组首次发现陶瓷材料也像金属材料那样具有异常的延伸现象,这种现象称为超塑性现象。众所周知,金属材料有具延伸性质,已在工业上广为利用。与金属材料相比,具有良好的耐热性、耐腐蚀性和耐磨性的陶瓷材料,由于其容易损坏(脆性)且坚硬,很难进行加工,因而难于用作工程材料。 Summary According to the report by Japan’s Labor Saving and Automation magazine (December 1985), the Japan Institute of Technology, Nagoya Industrial Technology Laboratory ceramic evaluation technology research group for the first time found that ceramic materials also have an unusual extension like metal materials, this Phenomenon is called superplastic phenomenon. As we all know, metal materials have extended nature, has been widely used in industry. Ceramic materials having good heat resistance, corrosion resistance and abrasion resistance are difficult to be processed as engineering materials because they are easily damaged (brittle) and hard and difficult to process as compared to metal materials.
