Abstract
The spacing of the dendrite arms has been measured in a large group of nonferrous alloys cast under comparable conditions, from which it has been learned that:
-
1.
The dendrite arm spacing and the grain size are independent.
-
2.
The dendrite spacing is inversely proportional to the rate of freezing.
-
3.
Alloying coarsens the dendrite.
-
4.
The dendrite spacing in any one alloy system varies in the same manner as the ratio of the heat of fusion to the thermal diffusivity.
