Abstract
The novel tantalum-containing ferritic heat-resistant steel BW2 is currently being applied in 600℃steam turbines.Alloy steel samples were processed using microwave digestion.Tantalum(Ta)with analytical line of 240.063 nm was selected,and method parameters were optimized to determine Ta in alloy steels using Inductively Coupled Plasma Optical Emission Spectrometry(ICP-OES)method.This method is characterized by its simplicity and convenience.The results indicated that the linear correlation coefficient of the calibration curve exceeded 0.999,and the recoveries ranged from 90.0%to 105.0%.For alloy steels with Ta contents ranging from 0.004 2%to 0.039 0%,the precision could meet the required standards,and the limit of quantification for the method was 0.002 8%.The research findings can provide reference for rapid and accurate determination of Ta in new types of alloy steels,such as BW2.关键词
