Alfred Stansfield, Montreal, Canada:—In Professor Howespaper on the position of Ae3, he shows its industrial importance indetermining the temperature to which steel should be heated for grain refining. Several years ago I carried out a research on the burning of steel and found that while hypo-eutectoid steel shouldbe heated to Ae3, hyper-eutectoid steel that has been very muchoverheated must be reheated to the curve Sa on the carbon-irondiagram, in order to redissolve the pro-eutectoid cementite and thusto obtain recrystallization and grain-refining. This treatment wasnecessarily only partly successful, and I should like to ask whetherthe conditions of heat treatment for refining overheated high-carbonsteels have been ascertained.
