Wonder metal
The story of titanium is extraordinary.To begin with,it was discovered twice.A British scientist,William Gregor, found it first and called it menachanite and six years later, in 1797,M.H.Klaproth, a German chemist, also found it and gave it its present name.
For many years,titanium was of interest only to research chemists – it considered too brittle to be of any practical value.
It cost the chemists in many countries endless efforts to isolate pure titanium
and even more to start producing it commercially.In 1948 the world stock
of pure titanium was only ten tons. Today the output is much larger.
Titanium has one surprising property – it is completely inert in biological
media,sometimes the medical community was quick to notice. It is being
used to make artificial joints and many other things necessary in surgery.
Titanium's instruments do not corrode,are thirty per cent lighter than
instruments made of stainless steel.
Titanium's high standard of corrosion resistance,lightness, tensile, strength
and the ease of forging, rolling and stamping are finding it more and more

uses.Titanium alloys are very useful in mechanical engineering.It shows
good work at chemical plants, in the pulp-and -paper and food industries.
Moreover, it is still a source of surprise for the investigator.
A group of researchers under the leadership of Prof.Kornilov produced a
material that has a kind of “memory”, as the following experiment shows:
a thin bent strip of the new alloy was clamped to a stand, a 500-gram weight
hung on the free end. A current was passed through for several seconds,
which heated the strip to more than 100 *C. As if commanded by an
enigmatic force,it straightened out like a tight spring and lifted the load.
When the current was switched off,the strip gradually went back to its
original shape.The cycle was repeated a number of times,and the strip
always “remembered” its original shape. The surprising phenomenon of
direct conversion of thermal energy into mechanical is seen with the
naked eye.
