Evaluation
of the thermal integrity of fin-tube joints of an actual
heat exchanger. Idealized conditions for the comparison determined
by numerical predictions of the joint formation. Actual joint
formation determined from metallographic cross sections.

Formation of a solidified joint between metallic and/or nonmetallic
materials is a critical phase of a manufacturing process called
brazing. A hypothesis may be introduced as follows: "The topology
of the solidified brazed aluminum alloy joint can efficiently be
described by an equilibrium membrane of the liquid alloy at the
onset of solidification." This research program is devoted to verification
of the validity of the above formulated hypothesis.
Experimental studies involve the real time monitoring of the cladding
flow, the metallographic studies of brazed coupons and complex geometry
samples, interface phenomena (in particular diffusion of Si and
Mn at the atomic level), etc.
