摘要：

Results of dilatometrichesky researches of the silicon alloys containing 30-49 % of aluminum, are given in a range of temperatures of test 50-450 degrees C. Features of influence of thermal and thermocyclic processing on size and nature of change of temperature factor of linear expansion of alloys are studied. It is shown that application of effective ways of processing pac Pi Pi aBa in a combination to the subsequent thermocyclic processing allows to receive easy alloys of invarny type with Temperature factor of linear expansion which is not exceeding 7,3 . by 10(-6) K-1 in the specifi ed range of temperatures of test.
