摘    要:回顾中国钛及钛合金标准从雏形的建立和3次重大改进,阐述历次改进的重点,特别是2007年至今钛标准体系的重要变化及完善情况,如大量纳入新研制的钛合金牌号、纯钛的化学成分及力学性能实现与国际的接轨、加强检验标准的系统完善,制修订近10项方法标准,部分性能检验方法与国际接轨、注重产品标准新类别的制定,包括铸锭、网板、焊接管、挤压管及钛废料等。并与国际和国外先进标准体系进行对比分析,标准体系整体达到国际先进水平。提出进一步完善我国钛标准体系的发展思路和建议:提高标准的认知程度,达到国际通用;加快新研发合金的纳标,推动新合金的应用;加强方法标准的制定,使标准体系更加完善。

Abstract: The Chinese National Standard (GB) system of titanium and titanium alloy from the establishment and development of three major changing stages was reviewed, and the important changes in the system and improvement situation in Chinese Titanium GB, in specialty, the important changes since 2007 years. including the development of new designations, adoption of international practices in chemical composition and mechanical property, perfection of basic standards and testing methods for the standard system, about 10 test method standards were constituted and revised. The international practices in part of the performance test methods, establishment of new classificatory product standard, including ingot, halftone, welded tube, extrusion tube and titanium scraps, etc were adopted. The international and foreign advanced titanium standards system reaching international advanced level were compared, and further improvement ideas and suggestions on Chinese titanium standards system development: heighten standard cognizing degree to achieve international currency; quicken standardization of new developed designations to promote new alloys application; strengthen constituting method standards were proposed to make Chinese titanium standard system more perfect.
