Chaired Assist. Prof. Dr. Ahmed Ali Akbar Akbar, head of
production Engineering and Metallurgy department discussion masters
student (Neam Fawzi Mohammed) from
Metallurgical Engineering Branch for her thesis "Effect of Clearnes on
Diffusion in Brazing of Aluminum Alloys" on Thursday, 19/01/2017 in the
Dr. Ibrahim Mahmoud Mansour class at nine in the morning and the
Committee comprised discussion of the membership of Assist. Prof. Dr.
Raed Kadhim Salem from Babylon University / technical College, and Prof.
Dr. Abbas Khamas Hussein from the Department of Materials Engineering at
the University of Technology and was under the supervision of Lec.Dr.
Baha Sami Mahdi from the Department of Production Engineering and
Metallurgy,The thesis includes studying the effect of allowing
temperature and time display welding mortar using two types of metal
fillings Aluminium metal base, which is a pure alloy of aluminum
(aluminum trade) has conducted tests microstructure of each metal
foundation and mineral fillers in the welding area carried out on two
types of oblique sample designs and cylindrical been a tensile test by
cutting them solo to the samples that have been prepared and welded and
conducting tests microscopic structure using an optical microscope and
electron microscope (EDS-SEM) vertical sections of welding line and
aspects of the fracture to the study of the nature and depth of
deployment in connecting area and hardness microwave and using the
program ImageJ software was determined depth Depth of outreach in the
area of connectivity has also been conducting tests X-ray diffraction (
XRD-Diffraction) to see eccentric formed in the connecting area, and the
results showed that the highest values of tensile strength was 145MPa so
as to alloy metal fillers AL- 12% Si and at a rate allow ranging from
(250-350μm) the highest value of the strain resistance recorded for
mineral fillers of some sort AL - 5% Si was 176MPa and the value of
optimal allow ranging from (μm150-250μm) .In general study proved that
the effect of allowing a direct impact on the value of solvent and
spread on a metal base and fillers in the alloy of aluminum, as well as
on the mechanical properties of the connection welding, has expressed
chairman of the discussion Assist.Prof.Dr. Ahmed Ali Akbar Akbar remarks
sound as amended value that helped enrich the practical side and the
results of that thesis. At the end of the discussion the Committee's
decision to award the student master a very good grade.
