FIELD: powder metallurgy, particularly, heat resistant alloys on the base of nickel monoaluminide. SUBSTANCE: alloy comprises aluminium oxide having dispersity less than 1 mcm. Nickel monoaluminide comprises 23.5-31.5 % of aluminium, content of aluminium oxide in alloy being 3.5-15.0 mass %. Strength of alloy is increased 4 times, strength during elongation at 20-1000 C is increased 1.5- times. EFFECT: increased strength of desired alloy. 1 tbl |
