5083铝合金与6063铝合金可以相焊吗?接用什么焊丝呢,

Japan Sky provided SP5083 alloy plates,to analyze its chemical composition for Al-4.6 Mg-0.67Mn-0.1Cr-0.02Cu-0.05Si-o0.05 Fe-o0.01Ti.Alloy billets are at 530 ℃ after 8 hours And so that homogenization by hot-rolled into a thickness of 6 mm followed by cold-rolled into a thickness of 2 mm.Plate at 400 ℃ after 10 minutes after the recrystallization treatment,the superplastic deformation proceeds in advance of the average grain size of 8.M.
In this study,at each trial on the use of etching plate diameter d0 (2.5mm) small circular grid to measure the strain rate.In the superplastic forming process of erosion of the small round will become deformed into a large oval or round.Were measured after deformation and short-axis diameter of the long axis of d1,d2 to determine the strain axis.Axis strain,equivalent strain,strain rate can be expressed as:
ε1 = ln (d1 + d0) (1)
ε2 = ln (d2 + d0) (2)
ε3 = ln (h/h0) (3)
=
=
Where:h0:initial slab thickness
h:plate thickness after deformation
ε1,2,3:1,2 and the direction of 3 axis strain
:Equivalent strain
:The actual strain rate
t:Forming time
2.2 Superplastic Forming Test
Stress inflatable cavity forming the shape,including rectangular and cylindrical.Standard cylindrical cavity diameter 40 mm and depth 20 mm.Rectangular cavity of 120 mm (L) * 40 mm (wide) * 20 mm (D).Die by the 4340 low carbon steel composition,its surface roughness Ra = 0.84?M,Ra value is the arithmetic average roughness.Superplasticity,through the availability of lubrication under argon deformation become a cavity.SUPFORM2 computer program to calculate the desired strain rate in stress distribution.In order to achieve the desired strain rate through a computer program to carry out trial run to modify the prediction of pressure distribution.Forming inflatable stress at 525 ℃ and strain rate under separately fo
