Abstract Scope |
The contributions of R. F. Mehl to physical metallurgy are well-known. One of his most admired contributions is the formulation of recrystallization theory, which is now known as JMAK (Johnson-Mehl-Avrami-Kolomogorov) theory. The presenter has found some unpublished works of R. F. Mehl in metal fatigue, which seem to reveal his critical thinking and attempts in formulating a quantitative theory for S-N fatigue behavior of metals. Mehl also seemed to have undertaken one of the earliest studies on the statistical aspects of fatigue. He, along with coworkers, also explored the question of reliable determination of endurance stress limit in fatigue. The presenter will highlight Mehl’s contributions to the understanding of metal fatigue and its statistical aspects, which have remained in obscure technical reports. It will also be shown how the physical theory of metal fatigue, recently formulated by the presenter, is also validated by Mehl’s early analyses in this area. |
