Research on GH4169G alloy for aerospace turbine disk

摘要

Using metallographic observation and mechanical measurement,the microstructure and mechanical properties of GH4169G alloy has been investigated.The effect of the phosphorus,boron trace elements on mechanical properties of the GH4169G alloy are compared and analyzed.The results showed that the hot-workability of the GH4169G alloy is very good.The stress ruptures properties of GH4169G alloy is over 3 times than the traditional GH4169 alloy.
