It should be noted that testing above-described embodiment 1~7 respectively according to the relevant test method in GB/T228.1-2010
With tensile strength, yield strength, elongation percentage and the reduction of area of the alloy of comparative example 1~5；According to the metal surface GB/T1818-94
Rockwell hardness test method tests the hardness of the alloy of above-described embodiment 1~7 and comparative example 1~5.
Table 1
It can be seen that ambrose alloy silicon alloy made from the embodiment of the present invention 1~7 with very high from the test result of upper table 1
Intensity and hardness, tensile strength reach 1350MPa or more, and yield strength reaches 1200MPa or more, hardness reach HRC41 with
On, elongation percentage is 18% or more, 28% or more reduction of area.
Compared the test result of comparative example 1 and embodiment 2 it is found that being made after replacing graphene using common carbon dust
The tensile strength of alloy, yield strength, hardness, elongation percentage, reduction of area obviously deteriorate.As it can be seen that addition graphene can be significant
Improve the comprehensive performances such as tensile strength, the yield strength of alloy.
From the test result of comparative example 2~4 and Examples 1 to 7 it is known that the content of the element silicon of addition is lower than 4%
When, it is 4~4.5% that the tensile strength of alloy obtained, yield strength, hardness, elongation percentage, reduction of area, which are obviously inferior to silicone content,
Alloy；Also, when silicone content is adjusted to 4.6%, the tensile strength of alloy obtained, yield strength, hardness, elongation percentage, face
Difference is little when shrinkage and content are 4~4.5%, it is contemplated that the problem of production cost, preferably silicone content is 4~4.5%.
From the comparing result of comparative example 5 and embodiment 2, it can be concluded that, the tension that addition element silicon is remarkably improved alloy is strong
Degree, yield strength, hardness, elongation percentage, reduction of area.
For forging type ambrose alloy silicon alloy, excessively high silicone content can be such that the forgeability of alloy sharply deteriorates.In addition, according to
Nickel silicon alloy phasor, the nickel silicon alloy within 10% is with 1 phase (Ni of β3Si phase) exist, it is contemplated that forgeability requirement, therefore, this
Invention controls silicone content within 5% to guarantee that alloy has certain forgeability.
Element silicon will increase the mobility of alloy in alloy melting, be very beneficial for its molding for cast moulding alloy,
In general the silicon that 2% content is added beyond into the fabulous iron of forgeability can be such that the forgeability of iron sharply deteriorates.And
Its substantially not no forgeability of the alloy of 5% or so silicone content, and utilize forging technology described in the present invention
It can easily realize the forging of the monel of 4.5% or so silicone content of content, and finished forged product rate is not less than 85%.
