7、d 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 body interested in a subject for which a technica
8、l 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 Electrotechnical Commission (IEC) on all matters of ele
9、ctrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to th
10、e member bodies for voting. 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 document may be the subject of patent rights. ISO shall not be held responsible for ide
11、ntifying any or all such patent rights. 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 fourth edition cancels and replaces the third edition (ISO 3116:2001), which has been technically
12、revised. The reason for this fourth edition is to clarify that requirements for chemical composition relate to cast analysis, and to adjust elongation values for some alloys and tempers. BS ISO 3116:2007vIntroduction This International Standard classifies the commercially available magnesium alloys
13、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 licence under such pa
14、tent rights. BS ISO 3116:2007blank1Magnesium and magnesium alloys Wrought magnesium alloys 1 Scope 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, forg
15、ings, and plate and sheet. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

17、gnation 3.1 Material The material shall be designated by symbols as given in Tables 1 to 11. The material symbol designations are in accordance with ISO 2092. NOTE A list of national designations corresponding to this International Standard is given in Annex A and a table of physical properties of t
18、he listed alloys is given in Annex B. 3.2 Temper designation The following symbols shall be used for temper designation: O: annealed; F: as fabricated; H8: fully hardened (strain hardened to give maximum ultimate tensite strength); H4: half hardened (strain hardened to give an ultimate tensile stren
19、gth approximately midway between that of annealed and H8 temper); BS ISO 3116:20072 H2: quarter hardened (strain hardened to give an ultimate tensile strength approximately midway between that of annealed and H4 temper); T5: cooled from an elevated temperature shaping process and then artificially a
20、ged; T6: solution heat treated and then artificially aged. The temper designations are in accordance with EN 515. 3.3 Designations of product form The following symbols shall be used for product form: B: bars and solid sections; T: tubes and hollow sections; F: forgings; P: plate and sheet. 3.4 Desi
21、gnation for ordering EXAMPLE An order for magnesium bars, conforming to this International Standard, of magnesium alloy ISO-WD 21150, delivered in the as-fabricated condition (F) is as follows: ISO 3116 - ISO-MgAl3Zn1 (A) (or WD21150) - F - B Tonnage and dimensions are to be specified in addition. 4
22、 Requirements 4.1 Chemical composition The chemical composition of wrought magnesium alloys, taken as cast analysis at the time the material is cast, shall conform to the requirements for the appropriate material given in Table 1. 4.2 Mechanical properties The minimum values of the mechanical proper
23、ties of wrought products in magnesium alloys in the defined temper conditions shall be as given in Tables 2 to 11. 4.3 Frequency of testing The frequency of testing shall be subject to an agreement between the manufacturer and the purchaser. 5 Sampling Conditions for sampling, formation of batches a
24、nd frequency of verification shall be subject to an agreement between the manufacturer and the purchaser. BS ISO 3116:200736 Test pieces Test pieces shall be taken in the longitudinal direction. For rolled flat products of thickness 0,6 mm, test pieces may be taken in the long transverse direction.
25、7 Test methods 7.1 Chemical composition The determination of the alloying elements given in Table 1 shall be performed in accordance with normal practice. 7.2 Tensile test Tensile tests shall be carried out in accordance with ISO 6892. 8 Retests Conditions for retests shall be subject to an agreemen
26、t between the manufacturer and the purchaser. 9 Rounding of results The number representing the result for any value specified in this International Standard shall be expressed to the same number of decimal places as the corresponding number in this International Standard. The rounding of numbers sh
27、all meet the requirements of Annex B, Clause B.3, rule A or B in ISO 31-0:1992. The choice shall be left to the discretion of the manufacturer, unless the use of one of the rules is agreed by the time of acceptance of the order.
