Micro-and macrostructure of AA ER4043/nickel alloy Udimet-500 walls fabricated by wire-feed electron-beam additive manufacturing

The paper presents the data of optical microscopy of aluminum cast alloy ER4043 fabricated by wire-feed electron-beam additive manufacturing (WEBAM) and samples of composite material made by simultaneous double-wire feed EBAM with the introduction of 5% and 10% of the nickel alloy Udimet-500. The da...

Description
Summary:The paper presents the data of optical microscopy of aluminum cast alloy ER4043 fabricated by wire-feed electron-beam additive manufacturing (WEBAM) and samples of composite material made by simultaneous double-wire feed EBAM with the introduction of 5% and 10% of the nickel alloy Udimet-500. The data obtained testify to the complex and heterogeneous structure organization in composite materials made of dissimilar metals with different melting temperatures and densities. The data indicate the presence of non-melting nickel alloy on one side and overheating of aluminum alloy on the other side.
