A
hot short metal is ________ .
brittle
when cold
brittle
when hot
brittle under all conditions
ductile
at high temperature
brittle
when hot
Hot
short metals are those which become brittle at hot working temperature. If a
material is hot short, it means that the material is prone to cracking when its
temperature is close to its melting point.
Hence the correct option is (B).
&Key Points:-
●Hot
shortness is a tendency for some alloys to separate along grain boundaries when
stressed at temperature near melting point.
●This
is due to high sulphur content.
