31、ts are in the form of Didymium, with not less than 70 % Neodymium, and the remainder substantially Praseodymium.FAlloy EV31A is a patented composition, suitable for elevated temperature applications. Interested parties are invited to submit information regarding the identificationof alternatives to
32、these compositions to ASTM International. Your comments will receive careful consideration at a meeting of the responsible technical committee, whichyou may attend. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in thi
33、s specification. Usersof this specification are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their ownresponsibility.GOther Rare Earths may also be present to a total maximum of 0.4 %. These Rare Earths shal
34、l principally be Cerium, Lanthanum, and Praseodymium.HTotal Rare Earths (TRE) are principally a mixture of Cerium, Lanthanum, Neodymium and Praseodymium. The Cerium content should not be less than 45% of TRE.IOther Rare Earths shall be principally heavy rare earths, such as, Gadolinium, Dysprosium,
35、Erbium, and Ytterbium. Other Rare Earths are derived from the Yttrium,typically 80 % Yttrium, and 20 % heavy rare earths.JZinc + Silver shall not exceed 0.20 % in WE43B.B80072small amounts of grain refining elements and material for meltprocess losses are permitted.6.2 Pure materials and master allo

Manufacture7.1 The responsibility of furnishing castings that can be laidout and machined to the finished dimensions within thepermissible variations specified, as shown on the blueprint
37、s ordrawings, shall rest with the supplier, except when patternequipment is furnished by the purchaser. Sufficient stock shallbe allowed for shrinkage, and where requested, for finishing;but castings of excessive weight shall not be furnished.7.2 The castings may be subjected to such heat treatment
38、asdeemed necessary to produce material that will conform to therequirements specified. Heat treatment shall be performed onthe whole of a casting, never on a part only, and shall beapplied in a manner that will produce the utmost uniformity.8. Foundry Control8.1 When specified, castings shall be pro
39、duced underfoundry control approved by the purchaser. Foundry controlshall consist of examination of the castings by radiographic orother approved methods for determining internal discontinui-ties until the gating, pouring, and other foundry practices havebeen established to produce castings meeting
40、 the qualitystandards set by purchaser or agreed to between the purchaserand the producer. When foundry practices have been soestablished, the production method shall not be significantlychanged without demonstrating to the satisfaction of thepurchaser that the change does not adversely affect the q
41、ualityof the castings. Minor changes in pouring temperature of650F from the established nominal temperature are permis-sible.9. Chemical Composition Requirements9.1 LimitsThe castings shall conform to the chemicalcomposition limits prescribed in Table 1. Conformance shall bedetermined by analyzing s
42、amples taken when the castings arepoured, or by analyzing samples taken from the finishedproduct. If the chemical composition has been determinedduring the course of manufacture, sampling and analysis of thefinished product shall not be necessary.10. Sampling for Chemical Composition10.1 For determi
43、nation of chemical composition, onesample of each casting lot shall be taken in accordance withPractice E88 for chemical analysis or Practice E 716 forspectrochemical analysis.10.1.1 Samples for other methods of chemical analysis shallbe suitable for the form of material being analyzed and the typeo
