摘要：

The microstructure of a Ti-48Al alloy solution treated in the alpha-field is influenced by the cooling rate. The study of cooling curves permit us to determine experimentally the CCT diagram and to show that the higher the cooling rate the lower is the temperature of the alpha-->gamma transformation start. The evolution of parameters that characterise the lamellar structure has been determined according to the cooling rate. When this one increases, alpha(2)-volume fraction increases, width of alpha(2) and interlamellar spacing decrease. The values of yield stress also increased and were all the less scattered as the structure became more perfectly lamellar.
