Abstract

Annealing treatments originating in the beta field appeared to produce a stable condition more rapidly than annealing treatments originating in the alpha-beta field. Instability found in a 5 per cent chromium alloy is related to the formation of eutectoid products. The substitution of molybdenum for half of the chromium retards the eutectoid reaction resulting in a more stable condition. Small additions of oxygen to the chromium-molybdenum alloys do not appear to affect stability.
