BS ISO 3116:2019 pdf free download – Magnesium and magnesium alloys一Wrought magnesium and magnesium alloys.
This document classifies the commercially available magnesium alloys into a number of grades suitable for the application to which they might be put.
Some of the alloys referenced in this document 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 patent rights.
Details of heat treatments are given in Annex C.
4.3 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.
4.4 Designation for ordering
EXAM PLE
An order for magnesium bars, conforming to this document, of magnesium alloy MAZ31a, delivered in the as- fabricated condition (F) is as follows:
Iso 3116 – ISO-MgA13Zn1 (A) (or MAZ31a) – F – B
Tonnage and dimensions shall be specified in addition.
5 Requirements
5.1 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 2.
5.2 Mechanical properties
The minimum values of the mechanical properties of wrought products in magnesium alloys in the defined temper conditions shall be as given in Tables 3 to 48.
5.3 Frequency of testing
The frequency of testing shall be subject to an agreement between the manufacturer and the purchaser.
6 Sampling
Conditions for sampling, formation of batches and frequency of verification shall be subject to an agreement between the manufacturer and the purchaser.
7 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.
8 Test methods
8.1 Chemical composition
The determination of the alloying elements given in Table 2 shall be performed in accordance with the relevant International Standards, or other standards as agreed between the supplier and the customer.
8.2 Tensile test
Tensile tests shall be carried out in accordance with ISO 6892-1.
9 Retests
Conditions for retests shall be subject to an agreement between the manufacturer and the purchaser.
10 Rounding of results
The number representing the result for any value specified in this document shall be expressed to the same number of decimal places as the corresponding number in this document. The rounding of numbers shall meet the requirements of ISO 80000-1:2009, B.3, rule A or B. 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.
