Effect of cooling rates on dendrite spacings of directionally solidified DZ125 alloy under high thermal gradient
The dendrite morphologies and spacings of directionally solidified DZ125 superalloy were investigated under high thermal gradient about 500 K/cm. The results reveal that, with increasing cooling rate, both the...
