The lightweight construction philosophy is based on the principle of making the best possible use of the material. Whenever
a single material does not satisfy the demands of a specific application, compound structures may generate a solution.
Especially in lightweight construction, a multi-material-mix can provide ideal specific properties that are suitable for the
conditions to which a part is subjected. Typically such combinations of dissimilar materials provide desired properties in
various areas of the single part. Compound casting is a process, which yields such multimaterial components. The technique
is not much old and a few researchers have worked on it. However, the paper presents a recent reviews of literature on
compound casting. In this paper, the literature on compound casting is reviewed in a way that would help researchers,
academicians and practitioners to take a closer look at the growth, development and applicability of this technique. The
review aims at providing an insight into the compound casting process backgrounds and shows the great potential for further
investigations and innovation in the field. The survey of existing works has revealed several gaps in the fields of substrate
pretreatments, continuous flow behavior of metal during the process, correlation between mechanical and geometrical part
properties, and industrial application of some advanced processes.
Keywords: Compound casting, Literature, Interface

Nimonic-90 is a nickel based super alloy which is specifically used in aerospace industry for jet engines, valves, blades etc
owing to its high strength at high temperature, fatigue and corrosion resistance. Present work focuses on machinability of
Nimonic-90 with wire electrical discharge machining (WEDM) process. Cutting speed is considered as machinability
attribute in present work. Influence of WEDM parameters namely discharge current (Ip), pulse on time (Ton), pulse off time
(Toff), servo voltage (SV) and wire feed rate (WF) has been investigated on cutting speed of Nimonic-90.
Keywords: WEDM, Nimonic-90, cutting speed
