从标准的制修订看ADI生产技术的进步

Progress of ADI Production Technology Viewed from the Revision of the Standard

等温淬火球墨铸铁(ADI)由于具有高强度、高韧性、抗疲劳及耐磨、抗磨等综合性能,为21世纪人们关注的热点和最具发展潜力的材料之一。国外ADI的生产技术及应用发展较快,相关标准制定和更新比较及时而且不断完善。随着国内ADI生产技术水平的提高,我国ADI等温淬火球墨铸铁件的标准从早期的企业标准到国家标准、团体标准,形成了不同层级的标准体系。2009年我国发布了GB/T 24733—2009《等温淬火球墨铸铁件》,2021年发布了团体标准T/CFA 020101243—2021《等温淬火球墨铸铁件》;2022年又对GB/T 24733《等温淬火球墨铸铁件》进行了修订。从不同层级的标准制修订技术指标的提高可以看出我国ADI生产技术近十年来取得的进步。

Austempered ductile iron(ADI)is one of the most promising materials in the 21st century because of its high strength,high toughness,fatigue resistance,wear resistance and other comprehensive properties.The rapid developments of production technology and application in USA and European countries make related material standards revised and updated timely and continually.In China,the ADI standards from early established and issued enterprise standards to later national and group standards,formed different levels of standards,formed different level of standard system.In 2009 national standard GB/T 24733—2009“Austempered Ductile Iron Castings”was published;in 2021,group standard T/020101243—2021“Austempered Ductile Iron Castings”issued;in 2022,the national standard GB/T 24733—2009“Austempered Ductile Iron Castings”was revised.The revise and update of different-level standards show great progress of China ADI production and technologies during last 10 years.
