第十二届世界钛会论文集(卷2)
内容概要

  第十二届钛会是系列会议的第十二届,钛会自1968年开始,每四年举办一次,旨在召集世界钛界同仁,共商钛科技发展大计。钛会覆盖了钛的各个方面,包括从矿石到成品的完整的生产路线,新合金和加工的发展,微观结构和性能的评价以及所有领域钛的应用。世界七大钛国,包括美国、俄罗斯、日本、英国、法国、中国和德国组成的国际组织委员会保证了钛研究、发展和应用的各个新的、感兴趣领域都将被讨论。

章节摘录

  Based
on
the
con-ventional
methods
mentioned
above,
a
novel
approachthat
measuring
the
mean
thickness
of
a
laths
in
colonyusing
Boolean
operation
is
proposed
in
this
work,which
is
shown
in
Figure
1.
The
feature
parameters
of
micro-structures
in
titanium
alloys
extracted
using
this
meth-od
include
phase
volume
fraction,grain
size,thickness
of
Widmanstatten
a
laths,
colony
scale
size,
thickness
and
orientation
of
a
phase.
It
not
only
reduces
the
errorwhich
is
associated
with
the
lineation
by
users
but
alsoenhances
the
reliability
of
measured
data.
Moreover,inorder
to
unify
the
measurement
standard
of
a
phase
in
the
basket
weave,mixed
and
equiaxed
microstructures
of
typical
titanium
alloys
and
take
the
continuity
andsimplicity
of
quantification
into
consider
ation,the
eval-uated
parameter
of
Feret
Ratio
was
referred
to
present
the
evolution
of
c,
phase
and
modeling
the
correlation
of
process,microstructure
and
mechanical
property
of
ti-tanium
alloys.
The
orientation
of
a
phase
was
presentedby
the
angle
to
the
primary
axis
of
a
phase
and
its
ver-tical
direction,which
suggests
that
the
characterizationmodel
of
evolution
and
orientation
behavior
in
a
phaseduring
hot
deformation
of
titanium
alloys
has
been
es-tablished,as
shown
in
Figure
2.
It
should
be
noted
that
the
proposed
model
has
been
successfully
applied
toquantitatively
exhibit
the
dynamic
evolution
of
a
phase
in
TC17
titanium
alloy
with
lamellar
microstructure.Hence,the
realization
of
quantification
characterization
about
the
evolution
of
lamellar
a
phase
takes
place
of
the
traditional
method
that
whether
the
globularizationphenomenon
occurred.In
the
present
in
vestigation,with
the
help
of
the
basic
theory
of
stereology
and
quantitative
metallogra-phy
and
analysis
platform
of
quantification
image
soft-ware,a
rigorous
and
available
model
of
quantification
of
microstructural
features
was
developed.
Previously,the
phase
volume
fraction
was
measured
using
area
meth-od,and
the
mean
intercept
method
was
employed
tome
asure
the
grain
and
colony
size.  ……
