Technology saves at least 30% ~ 50% man-hour and reduces by 20% ~ 35% cost, and the processing benefit and economy for greatly improving part are imitated
Benefit.In terms of performance, because with metal material in the region of very little reciprocation occurs for high energy beam in a short period of time,
The strong heat exchange effect of cold conditions base material, causes laser molten pool and heat affecting around the quick heating of material surface regional area and molten bath
The cooldown rate in area can reach 102~106K/s or so, typical near quick setting and solid-state phase changes feature is presented, ensure that gold
Category part has good mechanical property.Alloy is that traditional casting alloy or forging are closed mostly used by increasing material manufacturing at present
Gold, but the composition design of these alloys is in the technology characteristics of casting or forging process, tissue and alloying feature for alloy
And strengthened mechanism, and the operational characteristic of increasing material manufacturing determines its tissue and alloying feature certainty and traditional casting or forging
Part has bigger difference so that the design of these alloys can not generally give full play to the mechanical property of increasing material manufacturing component, it is necessary to
The design of increasing material manufacturing special metals is re-started, and the alloy that is mainly characterized by of increasing material manufacturing undergoes from melting in a short time
To the overall process of solidification, therefore core sorting basis are the compatibility with high melt stability and melt and solid structure,
And from the point of view of structure root, the various performances of material are relevant with chemical short-range order.Chemical short range sequence structure is described by introducing
Cluster adds connection atom model, finds corresponding short-range order construction unit and its empirical formula, is the accurate control shape control of increasing material manufacturing
Property provide special metals material sorting basis.
