Abstract

The aim of this work is to study the microstructure of severe cold work copper wires,
which its already processed at Ur Foundation (Nasyeria) which in Ur are cold drawn from 10
mm to 2 mm in diameter, then at final process it will be treated automatically by treated box
by 200
o
C (semi treatment). Our work dealing with taken the final drown wire (2 mm in dia.)
and doing a laboratory treatment by 200
73

o
C, 300
o
C, 400
o
C, and 500
o
C, one hour at this
temperature and the furnace cooled. The result which concluded that the Ur treatment is hot
full treatment but a stress relief one with almost same wire property. While the treated wires
show a recrystallized structure with inclination by 45
0
angle for this structure. The high
treated temperature shows grain growth and demises the 45
0
angle structure
