FIELD: metallurgy.
SUBSTANCE: method for obtaining material in the form of a cast section involves preparation of aluminium melt containing 1-2 wt % of iron and 0.2 - 0.6 wt % of silicon, introduction to the melt at the temperature of 900-1100°°C of boron in the form of boric acid and titanium in the form of chips in the ratio allowing to obtain in cast structure of titanium diboride particles in the amount of 4 to 8 wt %, and crystallisation by casting to a mould.
EFFECT: obtaining boron-containing composite material on aluminium basis, which has high level of absorption of neutron emission in combination with the best mechanical properties and processibility.
