Detailed description of the invention
Below the specific embodiment of the present invention is described in detail.In the following description, unrestricted for explanation
Property purpose, elaborate detail, with help be apparent from the present invention.It will be apparent however, to one skilled in the art that aobvious and
Be clear to is, it is also possible to put into practice the present invention in departing from the other embodiments of these details.
Embodiments provide the fusing of a kind of selective laser and shape 0Cr17Ni4Cu4Nb stainless steel material heat treatment work
Skill, including annealing temperature and time, solid solubility temperature and time, aging temp and time.
Wherein, owing to shaping the cooling of process in which materials rapid solidification in selective laser fusing, part exist bigger residual
Residue stress, therefore selective laser fusing should carry out stress relief annealing after shaping as early as possible；
Solid solution process makes austenitic formation and homogenization in stainless steel material microstructure, makes intensified element and carbon solid solution
In austenite, mainly dissolve the copper-rich phase of original precipitation；
Ag(e)ing process makes martensite in stainless steel material microstructure be that lath-shaped is uniformly distributed, on martensitic matrix and
Tiny carbide particle is separated out between lath.
Technology for Heating Processing flow process includes annealing, solid solution and timeliness, annealing process: argon is cold to be incubated 4 hours again at 650 DEG C
But；Solid solution craft: be incubated 1.5 hours argon at 1150 DEG C and be cooled to 1040 DEG C and be incubated 1 hour, then argon cooling；Timeliness work
Skill: argon cools down to be incubated 4 hours again at 540 DEG C.
Its operation principle is: owing to selective laser fusing shapes the cooling of process in which materials rapid solidification, exist relatively in part
Big residual stress, first takes annealing process to eliminate residual stress.Solid solution uses high temperature solid solution to tie with middle temperature solid solution phase
Close, accelerate formation and the process of homogenization of austenite, increase the dissolubility of carbides in austenite, make more intensified element
It is solid-solution in austenite with carbon, thus after solid solution, the saturation of martensite increases, retain after timeliness and separated out more
Copper-rich phase and hardening constituent carbide, strengthen alloy dispersion-strengthened action.In ag(e)ing process, Fine Texture of Material generation recrystallization, subtracts
The anisotropy of few material.
