In different patient's implants shape and size difference, it is necessary to according to the specific requirement of different patients carry out molding, this will
Take a substantial amount of time and cost.Increasing material manufacturing is a kind of based on mathematical model, will using high energy beam particle flux as thermal source
Material is point-by-point or successively accumulation forms the emerging manufacturing process of Three-dimensional Entity Components.Because whole process does not need any mill
Tool, compared with conventional art, increases material manufacturing technology saves at least 30% ~ 50% man-hour and reduces by 20% ~ 35% cost, greatly improves
The processing benefit and economic benefit of part.In forming process, the available CAD of any complicated Three-dimensional Entity Components is divided into
Simple two dimensional surface is successively processed, and processing flexibility degree is very high, and this is the disposable whole of the parts of complex precise
Body shaping provides perfect technical solution.In terms of performance, due to high energy beam in a short period of time with metal
In the region of very little reciprocation occurs for material, and cold conditions base material is strong around the quick heating of material surface regional area and molten bath
Heat exchange acts on, and causes the cooldown rate of laser molten pool and heat affected area to can reach 102~106K/s or so, present typical near fast
Rapid hardening is consolidated and solid-state phase changes feature, ensure that metal parts has good mechanical property.Closed used by increasing material manufacturing at present
Gold is traditional casting alloy or wrought alloy mostly, but the composition design of these alloys is being cast or forged for alloy
The technology characteristics of journey, tissue and alloying feature and strengthened mechanism, and the operational characteristic of increasing material manufacturing determine its tissue and
Alloying feature is inevitable to have bigger difference with traditional casting or forging so that the design of these alloys generally can not fully be sent out
The mechanical property of increasing material manufacturing component is waved, it is necessary to re-start the design of increasing material manufacturing special metals, and increasing material manufacturing is main
It is characterized in that alloy undergoes the overall process from melting to solidification in a short time, therefore core sorting basis are steady with high melt
The compatibility of qualitative 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.
The cluster that chemical short range sequence structure is described by introducing adds connection atom model, find corresponding short-range order construction unit and its into
Fraction, special metals material sorting basis are provided for the accurate control shape control of increasing material manufacturing.
The content of the invention
The present invention is based on the composition at eutectic point on Zr-Nb phasors, it is determined that the composition and forming property of the system alloy
Between rule, and the double cluster alloys proposed for Zr-Nb system alloys design a model, and the model is by establishing solid solution
In solute short-range order Local Structure, obtain most stable melt and between good melt and solid compatibility solid solution knot
Structure, so that it is determined that having the ideal composition of the Zr-Nb based alloys of favorable forming property.
