Increasing material manufacturing method.
Background technology
Patent of invention《Metal component moves micro- method of squeeze forming》(application number：CN201310139419 one kind) is disclosed
Mouldless shaping method, it is characterised in that：The metal bath of refining is continuously squeezed out from crucible bottom outlet (nozzle), below nozzle
About hundreds of microns are a horizontal base plates that can make x-y-z three-dimensional motions, and melt is in the small space that nozzle and substrate are constituted
In solidification with substrate shearing motion, in the case where three-dimensional manufactures software support, melt Layer by layer solidification stack shaping is not necessarily to mould
Tool.The key of this method is：Between nozzle and substrate (or the previous stack layer solidified) be one it is narrow it is semi-open,
The temperature of hemi-closure space, wherein melt must be strictly controlled in solid-liquid two-phase region, and a part of melt is made to solidify, remaining
Melt is then swept along and is travelled forward with the pressure inside crucible by the movement of substrate, makes the dendrite just solidified by this fortune
Dynamic to smash, crystal grain is refined, to make the performance of component be improved.Main problem existing for this method is：For many
For alloys in common use, ± 1 DEG C of difference is enough to make the fraction solid of melt to change, and is changed with induced viscosity, and temperature is low,
Viscosity is high, is conducive to shape, but be unfavorable for Coating combination；Temperature is high, and viscosity is low, is conducive to Coating combination, but is unfavorable for shaping.
Therefore, it is necessary to take certain method, make the variation of viscosity independent of temperature, the control that forming is combined with interlayer (interface)
Condition separates, to realize that metal bath direct forming (increasing material manufacturing) creates convenience.
