材料和构件的断裂给国民经济建设带来巨大的破坏,许多灾难性的事故造成严重的经济损失。针对材料断裂问题而开展的“材料微观结构与力学性能研究”,“六五”期间,取得科研成果36项,获奖7项。按已完成鉴定的17项成果估算,可增收节支4000万元以上。中科院金属所和鞍山钢铁公司完成的“耐压钢中白点形成规律与消除白点新工艺研究”,采用终轧快冷等温退火处理工艺,不仅消除钢中白点,提高了产品质量,还缩短了处理周期,每
The rupture of materials and components has brought tremendous damage to the construction of the national economy, and many catastrophic accidents have caused serious economic losses. During the “Sixth Five-Year Plan” period, 36 scientific research achievements and 7 awards were awarded for the study of material microstructure and mechanical properties. According to the results of the 17 assessments that have been completed and appraised, it can increase the revenue by more than 40 million yuan. Chinese Academy of Sciences Institute of Metals and Anshan Iron and Steel Company completed the “pressure-resistant steel white spots in the law and the new technology to eliminate the white point,” the use of rapid cooling isothermal annealing annealing process, not only to eliminate white spots in steel and improve product quality, but also Shorten the processing cycle, each
