METHOD OF PRODUCTION OF BLANKS OUT OF ALUMINIUM-SILICON ALLOYS

摘要

FIELD: metallurgy. ^ SUBSTANCE: upon production of melt it is modified by means of introduction of strontium at amount of 0.03-0.5% from mass of melt and successive introduction of beryllium at amount of 0.05-0.3% from mass of melt. With a speed titanium in form of alloyed rod is directly introduced into a casting chute. Further semi-continuous casting of ingots is carried out at metal cooling rate of 170-190C/min with the following hot deformation of ingots. ^ EFFECT: upgraded plasticity of hot deformed blanks and increased output of accepted parts after successive production of cold deformed semi-finished products of thin section out of blanks. ^ 2 tbl, 2 ex
