摘要： PURPOSE:To obtain a rapidly solidified Al powder alloy showing high tensile strength from a room temp. to a high temp. of about 300 deg.C by specifying the content of Si and Fe in an Al-Si-Fe-Cu-Mg alloy. CONSTITUTION:This rapidly solidified Al powder alloy contains, by weight, 5 to 15% Fe, 1 to 8% Si, 1 to 8% Cu, 0.1 to 5% Mg and the balance Al. In this alloy, Fe forms intermetallic compounds with Al, which are finely dispersed at the time of atomizing to increase its high temp. strength. In the case of 15%, the effect is saturated, and furthermore, the intermetallic compounds are largely formed to deteriorate its forgeability. Si enters into solid soln. in Al to strengthen the matrix of Al and to increase its strength, and furthermore, it increases its modulus of elasticity and deteriorates its thermal expansion coefficient. As for the amt. of Si to be added, in the case of 8%, brittle Al-Si-Fe intermetallic compounds are coarsened to deteriorate its strength.

摘要： PURPOSE:To produce a metal base composite with uniformly dispersed hard grains by classifying metal powder into plural classes, mixing the metal powder with the hard grains starting from the small grain diameter class toward the larger diameter class in order and hot-caking, when the herd grains of a small diameter are mixed with the matrix metal powder having a larger diameter. CONSTITUTION:The hard grains B having 10mu or small average grain diameter and the matrix metal powder A having larger average grain diameter than the hard grains, are mixed and hot-caked to produce the grain dispersed metal base composite. Then, the metal powder A is classified into A1, A2...An and at first, the metal powder A1 having the smallest grain diameter (the max. grain diameter is 13 or less times of the hard grains) is mixed with the hard grains B in the dry condition, and with this mixed powder C1, the metal powder A2 having the successively smallest grain diameter is mixed in the dry condition. In such a way, until the metal powder An having the largest grain diameter is mixed with the mixed powder in the dry condition in order, and the mixed powder Cn is hot-caked to a prescribed shape to produce the granular dispersion metal base composite having >=-0.5 or a larger dispersion degree D. By this method, the high performance of the composite having excellent strength and cold forgability is obtd.

摘要： PURPOSE:To provide a method for heat-treating aluminum precipitation aging type powder alloy member contg. Mg capable of obtaining high strength without machining even after T6 treatment. CONSTITUTION:In a method for heat-treating a precipitation aging type alluminum powder alloy member essentially consisting of Mg, solutions treatment is executed in an atmosphere of an inert gas. In Al-Cu-Mg series, Al-Mg- Zn series and Al-Mg-Si series in which Mg components immediately below the surface layer part are easy to reduce in accordance with the oxidation on the surface in the process of the solution treatment, by the atmosphere of an inert gas, the oxidation of Mg from the surface layer part can be prevented. Furthermore, because there is no change at all also in the Mg content immediately below the surface layer part, there is no decrease in the hardness from the surface layer part to the depth, so that the member can be used in a state excellent in fatigue strength and as cold-forged as cold working even if machining is not executed to the surface after T6 treatment. Moreover, there is no oxide layers on the surface layer part, and adverse influences such as attackability on mates caused by oxide on the surface can be eliminated.

摘要： PURPOSE:To obtain the alloy by incorporating Mn and Cr and specifying a composition in an alloy where hard grains of SiC, etc., are dispersed into an Al-Cu-Mg-Si series. CONSTITUTION:This Al alloy has a composition consisting of, by weight, 2.5-5.5% Cu, 0.3-2.5% Mg, 0.1-0.19% Si, 0.3-1.0% Mn and/or Cr, and the balance Al and further containing, if necessary, 0.02-0.7% Ti and/or Zr. The Al alloy can be prepared by dispersing one or more kinds among ceramic grains of Si, Si3N4, etc., metal grains of ferromolybdenum, Co-Cr-W-C alloy, Co-Cr-Mo-Si alloy, etc., and grains harder than the matrix alloy, e.g., intermetallic compound, such as TiAl and FeAl, by 0.2-5vol.% into the Al alloy matrix. This Al alloy combines superior strength and wear resistance with excellent cold forgeability and can be suitably used for producing engine parts, such as valve lifter and valve spring retainer.

摘要： PROBLEM TO BE SOLVED: To easily carry out a blanking operation after a hot press process in manufacturing a high-strength component using a hot press technique.
SOLUTION: In a hot forming process, a heated steel plate 8 is formed so as to have the shape including a flange portion 22 to be gripped between an upper die 12 and a lower die 14, a corner portion 24, and a vertical wall portion 26 sandwiched between the side wall of a punch 20 and the inside of the forming bore of the upper die 14. In a die 10, a part of the portion for gripping the steel plate by means of the lower die 12 and the upper die 14 is provided with a heat insulating portion 18 to be composed of a material having a heat conductivity lower than that of the other portion of the die 10. The heat insulating portion 18 has an ability for transferring the heat of the steel plate 8 lower than that of other portions of the die 10 when the heated steel plate 8 is gripped. Therefore, the cooling speed of the steel plate 8 at that portion is slower than that at other portions, and as a result, the increase of the hardness due to the quenching phenomena can be suppressed. The portion having low hardness is used as the portion for the blanking operation.
