摘要：

Alloy 718Plus is one of newly developed nickel superalloys following the world most used nickel superalloy IN718. Alloy 718Plus was developed by the Allvac company in USA. Principal requirements for the alloy design were increasing the temperature capability 55 degrees C higher than that of alloy 718, up to 700 degrees C, and conservation of comparable processing characteristics (workability and weldability) and economical characteristics (low cost of raw materials and production process) as alloy 718. Alloy 718Plus is mostly used in wrought state, but using of other production processes is also possible. This contribution deals with the investment cast alloy 718Plus. Analysis of heat treatment and alloy's microstructure and mechanical properties was performed.
