A method of forming a metal matrix composite component comprises: providing a body defining a mould cavity; covering a first surface of the mould cavity with a first reinforcement material; restraining the first reinforcement material relative to the body to restrict movement of the first reinforcement material in the mould cavity; adding a second reinforcement material to the mould cavity, the second reinforcement material being in contact with the first reinforcement material; adding molten metal to the mould cavity such that the first reinforcement material and the second reinforcement material become embedded in a continuous metal matrix when the molten metal solidifies.

The invention relates to a method and a device for casting a melt 4 of a metallic material by means of a furnace 2 of a low pressure casting device, which furnace 2 has a receiving space 3 and a riser tube protruding into said receiving space 3. By pressurizing the receiving space 3 with compressed air, the melt 4 in the riser tube 12 of the furnace 2 is pressed into a mold cavity 10 of a mold 7, wherein simultaneously, a magnetic field acting against the conveying direction 23 of the melt 4 is applied to the melt 4 of the metallic material by means of a magnetic element 16 arranged in the region of the riser tube 12.

The invention is directed to the interventionless activation of wellbore devices using dissolving and/or degrading and/or expanding structural materials. Engineered response materials, such as those that dissolve and/or degrade or expand upon exposure to specific environment, can be used to centralize a device in a wellbore.

An injection molding material for magnesium thixomolding includes: a powder containing Mg as a main component; and a chip containing Mg as a main component, in which a proportion of the powder in the injection molding material for magnesium thixomolding is 5 mass % or more and 45 mass % or less, and a tap density of the powder is 0.15 g/cm.sup.3 or more.

A method for manufacturing a powder-modified magnesium alloy chip for thixomolding includes a drying step of heating a mixture containing an Mg chip containing Mg as a main component, a C powder containing C as a main component, a binder, and an organic solvent to dry the organic solvent contained in the mixture, and a stirring step of stirring the mixture heated in the drying step.

A method for manufacturing a thixomolding material for thixomolding includes a drying step of heating a mixture containing a first powder that contains Mg as a main component, a second powder, a binder, and an organic solvent to dry the organic solvent contained in the mixture, and a stirring step of stirring the mixture heated in the drying step.

A method of heat treating high pressure die cast objects using pressure is disclosed. A high pressure die cast object is obtained and solution heat treated to above 700° F. for at least 2 hours at pressures between 0.5 and 35 KSI or at any pressure or range of pressures therebetween. This method of solution heat treatment with pressure reduces and/or eliminates blistered defects on the high pressure die cast object. The method of heat treating by solution heat treatment with pressure also allows an increase of yield strength and corresponding weight reduction upon redesign or substantially larger safety factors for the cast object.
