After ageing treatment, it is as follows to measure wire rod mechanical property：
The mechanical property of finished wire rod is surveyed in the different embodiments of table 1.
Solution treatment of the present invention is equal to obtain uniform supersaturated solid solution in order to dissolve carbide in matrix, γ ', is convenient for
Again the carbide and γ ' equal hardening constituents that particle is tiny, is evenly distributed are precipitated when timeliness, while eliminating since cold and hot working generates
Stress, so that alloy is recrystallized.Meanwhile solution treatment also can get suitable grain size, the crystallite dimension of material and
Even property has apparent shadow to the plasticity of high-temperature alloy material, toughness, intensity, the high-temperature creep resistance of alloy and processing performance
It rings.The present invention can be effectively by adjusting conjunction using the synthesis heat treatment process of suitable solid solution treatment process and aging treatment process
The crystallite dimension of gold reaches the performance of piston ring needs.
The present invention uses GH4169 and precipitation strength type nickel base superalloy, and γ ' is mutually the main strong of alloy in the alloy
Change phase, and the quantity of γ ' phases, form and distribution are to influence the deciding factor of piston ring final performance.The present invention by 900 ~
Solution treatment is carried out during 950 DEG C, with the raising of temperature, γ ' mutually gradually starts to dissolve, and crystallite dimension also increases therewith,
When temperature is 945 DEG C ± 5 DEG C, γ ' can be mutually completely dissolved, and the long main trend of crystallite dimension is most apparent, and the intensity of alloy can be shown
Writing reduces, and plasticity significantly improves, and is convenient for subsequent mechanical process, while it is preferable to also ensure that the piston ring after making has
High-temperature and durable and creep-resistant property.Temperature continues to increase, and crystallite dimension is grown up unobvious, the intensity and plasticity variation tendency of alloy
Also gradually slow down.
Hardness and strength reduce after solution treatment after high alloy wire forming, need to reach living by subsequent ageing treatment
The plug ring later stage, the selection of the temperature of ageing treatment was most important around circle, the mechanical performance of attrition process, total by experiment repeatedly
Knot obtains, can more there is the raising using high alloy silk material mechanical performance when ageing treatment is kept the temperature using two steps, especially when
740 ~ 750 DEG C when carrying out ageing treatment, γ ' is mutually in stable spherical shape in alloy, and by second step 640 ~ 650 DEG C be more than
After 1 hour ageing treatment, γ ' phase amounts further increase, and Dispersed precipitate spherical in shape is in the alloy, to ensure piston ring
There is excellent anti-oxidant, antifatigue and corrosion resistance under high temperature environment.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention
