Embodiment
Below, the preferred forms of the manufacture method of the aluminum alloy for plastic working that detailed description the present invention relates to reference to Fig. 1.
At first, % (following only represent) by weight with %, preparation comprises be selected from one or more (for example Fe:0.15%, Mn:0.05%, Cr:0.3%) among Fe, Mn, the Cr of Si:0.4～2.0% (for example 0.8%), Mg:0.4～2.0% (for example 1.0%) and total 0.5～2.0%, surplus is the aluminium alloy quench solidification powder (operation 1-1, Al alloy powder preparation section) that comprises the Al formation of unavoidable impurities.As the method for preparing the quench solidification powder, can carry out according to known manufacture method such as spray method, super emergency cooling solidification method (メ Le ト ス ピ ニ Application グ method), spining disk method, rotating electrode methods, consider preferred spray method (particularly high pressure gas spray method (ガ ス ア ト マ イ ズ method)) from being suitable for the industrial production aspect.In addition, when preparing this Al alloy powder, consider the deviation of mixing equably, intensity and unit elongation, the median size of preferred Al alloy powder is 10～150 μ m.Its reason be because, during the median size less than 10 μ m of Al alloy powder, will between Al alloy powder, cause cohesion, make with the aluminum oxide uniform mixing and become difficult, in addition, when the median size of Al alloy powder surpasses 150 μ m, coarse particle increases, it is difficult that the homodisperse of aluminum oxide becomes, and the deviation of intensity and unit elongation increases, and brings difficulty for plastic working.
Next, in above-mentioned aluminium alloy quench solidification powder, be the aluminum oxide (Al of 5～20 μ m (for example 15 μ m) with median size
2O
3) the amount blending dispersion of (for example 15%) obtains mixed powder with 10～25% in pot mill, with this mixed powder through cold isobaric be shaped (CIP) interim be shaped (operation 1-2, press molding operation).At this, Al
2O
3Median size be that the reason of 5～20 μ m is because during median size less than 5 μ m, the uniform mixing difficulty that becomes, when surpassing 20 μ m, thick Al
2O
3Increase, make unit elongation and plastic working reduction.
Then, with the mixed powder that is shaped temporarily by vacuumizing processings that outgas (operation 1-3, treatment process outgases).The degassing is handled under heating and is easily removed gas, also partially sinters, and therefore carries out vacuum outgas at 200～450 ℃.If temperature surpasses 200 ℃ in the stove, can remove the air or the moisture that in interim molding, absorb, if temperature surpasses 300 ℃ in the stove, can decompose and remove hydrate.Even these phenomenons are also taking place more than 450 ℃, if but the temperature of interim molding will cause sintering above 450 ℃, stopped up the gap between the inner powder of the interim molding of removing air, moisture.Therefore, the present invention is in order fully to outgas before sintering begins, and in the stove of 400 ℃ of temperature molding kept 1～6 hour (for example 1.5 hours) in stove.
Then, further, will under the high temperature of 500～600 ℃ (for example 550 ℃), keep the sintered shaped body of 1～6 hour (for example 4 hours), by hot extrusion or hot rolling pressure sintering (operation 1-4, pressure sintering operation).In this pressure sintering operation, during 500 ℃ of temperature less thaies, the oxide compound etc. that covers powder surface has interference to sintering, and sintering velocity slows down, and sintering is not carried out substantially, therefore preferably heats more than said temperature (550 ℃).If more than this temperature (550 ℃), powder itself fluffs soft, a part of fusion on surface.The fused solution that obtains after the fusion oozes out from crack of oxide compound of covering powder surface etc. etc., in the slit of landfill between powder, sintering is carried out fast.In addition, surpass under 600 ℃ the temperature, cause the fusion of powdered alloy, can significantly reduce the mechanical characteristics of hot-work material if remain on.In addition, if the hold-time than 1 hour weak point, can not fully be carried out sintering, so the hold-time was necessary more than 1 hour.Opposite, if the hold-time than 6 little durations, causes the alligatoring of the partial crystallization thing in the powdered alloy, the mechanical properties of hot-work material is reduced.Therefore, the preferred hold-time is 1～6 hour.
After the pressure sintering, forge the structural member (operation 1-5 forges manufacturing procedure) that processing obtains finished product.
