The O-line model is usually applied to precipitation crystallography.Its application to investigation of martensite crystallography has received little attention.In this paper,the relationship between O-line model and the prism matching model for martensite crystallography is established.The formulas in the O-line model are applicable to martensite crystallography.Analytical solution of the habit plane corresponding to the minimum shape strain has been derived.A calculation example of {3 10 15}f martensite in a ferrous alloy is provided.While the results are in agreement with the former models for martensite crystallography,the advantage of O-line model is that it offers analytical solutions,facilitating further systematic investigations.
