12、ntrolled Copy, (c) BSI ISO 3116:2001(E) iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member
13、 body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elect
14、rotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
15、 Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any
16、or all such patent rights. International Standard ISO 3116 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 5, Magnesium and alloys of cast or wrought magnesium. This third edition cancels and replaces the second edition (ISO 3116:1981) which has been tec
17、hnically revised. Annexes A, B and C of this International Standard are for information only.

18、agnesium alloys into a number of grades suitable for the application to which they might be put. Some of the alloys referenced in this International Standard can be the subject of a patent or of patent applications and their listing herein is not to be construed in any way as the granting of a licen
19、ce under such patent rights.

20、gnesium alloys Wrought magnesium alloys 1Scope This International Standard specifies the chemical composition and mechanical properties of magnesium alloys for wrought products in the form of bars and solid sections, tubes and hollow sections, forgings, and plate and sheet. 2Normative references The
21、 following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Interna
22、tional Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

27、imately midway between that of annealed and H?4 temper); ?T5: cooled from an elevated temperature shaping process and then artificially aged; ?T6: solution heat treated and then artificially aged. The temper designations are in accordance with EN 515. 3.3Designations of product form The following sy
28、mbols shall be used for product form: ?B: Bars and solid sections; ?T: Tubes and hollow sections; ?F: Forgings; ?P: Plate and sheet. 3.4Designation for ordering EXAMPLE An order for magnesium bars, conforming to this International Standard of magnesium alloy ISO-WD 21150, delivered in the as- fabric
