Production of high strength Al85Nd8Ni5Co2 alloy by selective laser melting

Bulk

high

strength

and

thermally

stable

Al 85 Nd 8 Ni 5 Co 2 samples

have

been

prepared

by

selective

laser

melting

(SLM).

The

alloy

shows

a
composite-like

microstructure

consisting

of

submicron-sized

stable

intermetallic

phases

dispersed

in

an

Al

matrix,

which

leads

to

high

compressive
strength

(1–0.5

GPa)

at

elevated

temperatures

(303–573

K).

These

results

indicate

that

SLM

is

an

effective

alternative

to

conventional

routes

for
producing

dense,

thermally

stable

and

near

net

shaped

components

from

high

strength

Al-based

alloys.
