Additive Manufacturing of Copper and Copper Alloys for the ASM handbook Volume 24A has been accepted for publication

The ASM Handbook chapter for Volume 24A, Additive Manufacturing of Copper and Copper Alloys has been accepted for publication.

This chapter, authored by CPAC Faculty Tim Horn and Diana Gamzina presents a review of the current literature and state of the art for the additive manufacture of pure copper and copper alloys.  The Chapter presents compiled data on AM processes and industrial practices, copper alloys used, selected applications, material properties and, where applicable, has compared these data and properties to traditionally processed materials.  The article is currently in press and is scheduled for online publication in the spring of 2020.

Material Selection guide for AM copper and copper alloys. OFE Cu offers the highest conductivity at the lowest strength. Alloying additions in solution affect a moderate increase in strength for a large cost to conductivity. Incoherent phases generally have a less potent negative influence on conductivity. Ageing CuNi and CuCr alloys balances strength and conductivity. Specific heat treatments annotated in the legend are as follows: (a) 2 hour HIP under Argon at 1075°C and 206.4MPa, (b) annealed at 450ºC for 4 h, furnace-cooled (c) Solution heat treat at 1020ºC for 1 hr, water quench, then age at 480ºC for 4 hr (d) Solution heat treat at 1020ºC for 1 hr, water quench (e)annealed at 450ºC for 1 h under N2, furnace-cooled, (f)annealed at 600ºC for 1 h under N2, furnace-cooled, (g)annealed at 700ºC for 1 h under N2, furnace-cooled.
