Probabilities of Magnetization

IN an earlier analysis of the B-H curves of polycrystalline iron it was shown that a simple `trichotomy' of the steep part of the curves could lead to useful estimates of the quantitative distribution of operative lattice orientation along any given direction in polycrystalline sheet material¹. Subsequent work was directed towards correlating such estimates with directional measurements of Young's modulus²; and it has been found that while the general trend of agreement is unmistakable, there is a consistent tendency for the trichotometrical method, when applied along the rolling direction, to yield a modest over-assessment of the operative percentage of [100] orientation.
