Study on Ductility of Ti Aluminide Using Artificial Neural Network

Table 1

Assumptions for categorizing literature data.

Sl. no.	Assumptions
(1)	Effect of alloying elements like Cr, V and Mn is same on ductility
(2)	Effect of alloying elements on various alloys Ti 44-52Al is same as on Ti48Al
(3)	Grain size means diameter of grain for equiaxed grains and interlamellar spacing for lamellar grain
(4)	Value of grain size for different composition follow the same trend as it follow for a specific composition and the trend is extrapolated
(5)	Ductility data referred from literature is for mean grain diameter
(6)	Ductility data for alloy type and grain size is the maximum ductility for the alloy in desirable heat treatment condition
