X-ray fluorescence spectrometry is used often to determine a wide range of elements in alloys. The technique provides rapid, accurate, and precise multi-element analysis that enables efficient melt process control. It is also widely used for certification and over-check analysis of product.
Although x-ray fluorescence has become a widely used technique of analysis by the nickel alloy industry, a test method has not been available for this technique for use by companies involved in the analysis of these alloys. In order to fill this gap, ASTM International Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials developed E 2465, Test Method for Analysis of Ni-Base Alloys by X-ray Fluorescence Spectrometry. The new standard is under the jurisdiction of Subcommittee E01.08 on Ni and Co and High Temperature Alloys.
“Test Method E 2465 will provide information on the proper method to calibrate and analyze nickel alloys for a wide range of elements,” says Pat Cole, chief chemist, Allvac. “Nickel alloy producers, end users of nickel alloys and contract analytical laboratories will all benefit from E 2465. It will likely be widely cited in material specifications that seek to specify methods of analysis.”
Subcommittee E01.08 is currently soliciting representation from the laboratories of producers as well as end users of nickel alloys. The subcommittee is seeking interested parties to participate in interlaboratory testing that will enable the expansion of the standard.
In addition, Cole says that participants are welcome to join in the development of two proposed new standards that the subcommittee is developing. These proposed standards are a performance-based method for the determination of nickel alloys via inductively coupled plasma emission spectrometry; and, a method for the determination of trace elements in nickel alloys via mass spectrometry. The subcommittee has also identified the need for a spark-atomic emission spectrometry method; Cole encourages anyone interested in chairing a task group on this project to contact him.
