It is generally assumed that during sprayforming the amount of micro- and macro-segregation in the sprayforms will be limited or absent because of low liquid fractions, small grain size and high cooling rate. This paper shows that macro-segregation c

In the present paper examples are considered of 2xxx, 7xxx, and 8xxx alloys in which spray casting has been used to achieve high solute contents. In the spray casting process there is minimal segregation with little need for subsequent homogenisation

In a factorial experiment a flock of mainly Romney Marsh hoggets was divided into four groups. Half the flock were shorn at week 0 (28.4.70), 3 weeks before the factorial experiment began, and half were left unshorn; of each of these, from week 3 hal
