Description
Technical field
The present invention relates to a kind of preparation method of alloy, particularly relate to a kind of preparation method of Steel Alloy.
Background technology
The impelling strength of steel is very large to the performance impact of steel, and it tests the resistivity of Steel Alloy to external impact load.If Steel Alloy impelling strength is high, when being subject to external shock, external energy can be absorbed, the change produced the performance of self is less, if impelling strength is too low, then Steel Alloy fragility is comparatively large, when being easily subject to external shock, fracture or other phenomenons occurs, find a kind of Steel Alloy with good impelling strength, have the good market space.
Summary of the invention
The technical problem solved: the problem of the material impact poor toughness that conventional Steel Alloy preparation method obtains.
Technical scheme: the preparation method that the invention discloses a kind of Steel Alloy, preparation process is as follows: (1) gets each chemical composition, chemical component weight per-cent is as follows: Ta is 0.14% ~ 0.23%, Cs is 0.35% ~ 0.46%, Zn is 0.67% ~ 0.78%, Os is 0.55% ~ 0.58%, Si is 2.5% ~ 5.4%, Co is 8.3% ~ 9.1%, and surplus is Fe; (2) dropped in vacuum induction furnace by uniform composition each in step (1), temperature is set as 1340 ~ 1360 DEG C, pressure is 0.004 ~ 0.006Mpa, carries out vacuum melting, and after melting, casting obtains rod iron; (3) rod iron obtained is maintained the temperature at 960 DEG C ~ 980 DEG C, keep 6h; (4) rod iron is carried out anneal, annealing rate is 20 DEG C/s, is cooled to room temperature with induction furnace.Wherein smelting temperature is preferably 1340 DEG C; Melting pressure is preferably 0.004Mpa; In Steel Alloy chemical constitution, Ta is preferably 0.14%; In Steel Alloy chemical constitution, Si is preferably 2.5%.
Beneficial effect: the steel alloy material that the present invention prepares has good impelling strength, testing standard is GB/T1817-1995, and impelling strength is 500 to 580J, has good impelling strength.
