B vs. H Curves for E706 Ma@%& Yoke of Russian Steel W. Baker, R.P. Smith, 0. Mikhailov,

A. Ito, E. Black, W. Yang

We hew? measured B vs H curves fran four samples of Russian steel for E706 magnet yoke. The samples were machined into a toroidal shape of about 2" OD, 1.75" ID and l/2" height. There are three range of measurements fcr each sample as shown below:

Sample Range of Measurement with Max = 20kg 0 to 65 Oersteds, 0 to 180 Oersteds, 0 to 585 Oersteds

List I, Steel 08 Yes Yes YSS List II, Steel 08 YC?S Yes Yes 5257-00-00-05-01 Yes Yf3? YeS 5257-00-00-05-05 Yes Ye3 Yes

The results reduced to 8x11 size are shown in Figures 1 to 12. Copies of the full size originals can be obtained from W. Yang.

For the List I, Steel 08, we listed the B & H parameters for programmers who run Linda, Trim, or Poisson. See Table I. The values in the tables are the averge B values of the hysteresis loop.

Finally for comparison: (1) we plotted the results from List I, Steel 08 on a USS Steel 1010 graph, (2) we plotted the List I. Steel 08 vs the measured values of 1008 Steel from TM 1197, as shown in Figure 14.

The sample8 were measured by Arnold Engineering, Marengo, IL, with accuracy of + 3%.
