00:00:00
So with that and everybody. Um and made
00:00:06
the long and I made my project at its
00:00:09
image in should from as you can see
00:00:12
here the goal of my project was to
00:00:15
improve rolling capabilities of
00:00:17
different metal for the investigation
00:00:19
of their remote mechanical properties.
00:00:23
But starting starting from the
00:00:25
beginning when it became time for me to
00:00:29
look for master thesis project I
00:00:33
decided to look for an industrial
00:00:35
project in the field of matters. So why
00:00:38
industry mainly because all these
00:00:43
trends transversal skills we build so
00:00:46
much about to date. And wind energy
00:00:49
well it was just personal interest it
00:00:53
was then my EPFL supervisor who
00:00:56
suggested me to contact PX group yeah
00:01:01
one of the former PHD student of the
00:01:06
directory of mechanical met under. And
00:01:08
that's how I got the opportunity the
00:01:11
opportunity to work at a customer
00:01:14
"'kay" segment maybe part of the X
00:01:19
group they're producing semi finished
00:01:22
products made out of non precious
00:01:27
metals under the form of precision prof
00:01:29
I have or precision tools. And this
00:01:33
prods products are then used in the
00:01:36
what's making industry or in the make
00:01:38
medical industry for example all these
00:01:41
products are fabricated using using
00:01:45
called the formation techniques or
00:01:47
continuous merely now the problem is
00:01:50
that when you use all the formation not
00:01:53
all materials can be shaped property in
00:01:56
the case of call routing for examples
00:02:00
you can have edge cracking I'll
00:02:03
training or well different problems
00:02:05
appearing and although in some cases
00:02:09
you might have a chance to overcome the
00:02:11
problem by increasing the number of
00:02:14
running past or increasing the number
00:02:17
of the kneeling treatments it reduces
00:02:21
significantly predictive it based on
00:02:24
this statement and the idea of my
00:02:26
project was to evaluate how I moderate
00:02:29
increase in temperature two hundred to
00:02:32
four hundred degrees which is not too
00:02:34
complicated to implement in the
00:02:36
production line could help overcoming
00:02:39
this problem to tackle this problem. Um
00:02:44
it was really a collaboration between
00:02:46
yeah yeah and I met in the first part
00:02:49
of the project I carried then side. S
00:02:53
at EPFL at different temperatures to
00:02:55
evaluate the evolution of a mechanical
00:02:58
properties of the different materials I
00:03:01
was studying and this allowed choosing
00:03:05
a running temperature once this was
00:03:08
done it was time to move to press
00:03:10
cement production line. And today up
00:03:13
keeping matter that was able to reach
00:03:17
the temperature we chose. Um and that
00:03:19
was compatible with the production line
00:03:22
and finally when all this was done we
00:03:26
carried I were rolling that and each
00:03:29
sample brought sample was than a light
00:03:33
in terms of well hardness
00:03:35
microstructure dimensions a crack size
00:03:38
exception here is an example of the
00:03:43
test the results that were obtained for
00:03:45
titanium great to which is basically
00:03:48
pure sliding it on the left side you
00:03:51
can see the rest of that was obtained
00:03:54
for sixty eight percent are we are
00:03:56
reduction under cold running conditions
00:04:00
and on the rights the rest of that was
00:04:02
obtained using the same rolling past
00:04:05
but under what were rolling conditions.
00:04:09
And we found that in that case or
00:04:12
rolling a Lowes read using cracks that
00:04:16
edge right size significantly in in
00:04:20
numbers it was actually observed that
00:04:23
for our we have reductions bigger than
00:04:25
fifty eight percent we have extract
00:04:29
side that is actually three times
00:04:31
smaller in the case of form rolling
00:04:33
compared to call routing. And we also
00:04:36
up there that bigger that can be used
00:04:41
without affecting see few significantly
00:04:44
the edge crack size which means that in
00:04:48
this case we're rolling seems to be
00:04:52
quite efficient unique increasing
00:04:54
productivity a titanium great at least
00:04:59
it has the potential to increase the
00:05:01
productivity not coming to my in
00:05:05
personal impressions so making a matter
00:05:10
of these this project industry is
00:05:12
really a great and maybe unique
00:05:14
opportunity to combine production
00:05:19
problematic with academic research
00:05:21
approach. Um and it's also a very good
00:05:25
opportunity to acquire skills that are
00:05:28
not to look at EPF concerning well
00:05:34
devices. Um if you don't have a project
00:05:38
it's there is the box they just that
00:05:41
but if you don't find anything they're
00:05:44
just don't hesitate and ask professors
00:05:47
that's what I didn't well it worked
00:05:49
well and once you have a project just
00:05:52
be sure that's the object itself the
00:05:55
projects are well established between
00:05:57
your academic supervise or you and your
00:06:01
industrial supervisor because well
00:06:04
sometimes you can have beverages in my
00:06:08
kids everything was defined well and it
00:06:12
works there. So thank you for your
