It is the first furnace able to produce either equiax or
directionally solidified crystals, Boutot said.
A GE team conducted creep feed grinding tests on three different nickel-base superalloys: conventionally cast IN-718, single-crystal Rene alloy, and
directionally solidified Rene.
Selected longitudinal (parallel to the horizontal growth direction) sections of the
directionally solidified specimens at 5, 10, 15, 20, 30, 40, 50, and 60 mm from the metal/mold interface were polished and etched with a solution of 0.5% HF in water for micrograph examination.
In metalcasting, three different grain structures can be achieved: equiax,
directionally solidified poly-grain and the single crystal.
A356 with and without strontium modification also was
directionally solidified. Other findings from the study include:
A
directionally solidified sample (to control shrinkage) is obtained from the melt and machined into a small cylinder.
Fine grain superalloy castings, composite materials and
directionally solidified castings required to meet increased operational conditions will be "HIPed" more often.
VI melters are used in both primary and secondary refining to produce powdered metal,
Directionally Solidified (DS), equiaxed and Single Crystal (SC) cast parts or wrought products.
