A semi-solidified metallic material is formed having particles in solid phase of a particle size less than 30 μm, and is thereupon injected into a die. A die casting machine has a sleeve into which a melt of metallic material is poured, and the semi-solidifying material there when it has a certain proportion of solid phase reached is injected into the die with a plunger to which pressure is applied. The melt of metallic material is poured into the sleeve so that the material occupies inside the sleeve at a proportion in vertical cross-sectional area of 30% or less. The particle size in this semi-solid material is held unvaried in a product as diecast. Full Article
ic Method for producing a trailing arm of a twist beam axle in which a drive unit of an electrical drive close to the wheel, comprising an electrical engine and a transmission, is integrated By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A method of producing a trailing arm of a torsion beam axle in which an integrated drive unit of a wheel-adjacent electric drive has an electric machine and a transmission. By using the method, the trailing arm is produced in the form of a casting with a box profile. The contours for producing the area that accommodates the transmission, the connection point to the vehicle body, the bore that receives the cross-member which connects the two trailing arms to one another, the U-profile of the trailing arm, the box profile and the area that accommodates the electric machine, are modeled by cores such that the contours for producing the connection point of the trailing arm to the vehicle body, the bore that receives the cross-member and the U-profile of the trailing arm are modeled by one core.

ic Titanium based ceramic reinforced alloy for use in medical implants By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A titanium based, ceramic reinforced alloy ingot for use in producing medical implants. An ingot is formed from an alloy having comprising from about 5 to about 35 wt. % niobium, from about 0.5 to about 3.5 wt. % silicon, and from about 61.5 to about 94.5 wt. % of titanium. The alloy has a hexagonal crystal lattice α phase of from about 20 vol % to about 70 vol %, and a cubic body centered β crystal lattice phase of from about 30 vol. % to about 80 vol. %. The ingot has an ultimate tensile strength of about 940 MPa or more, and a Young's modulus of about 150 GPa or less. A molten substantially uniform admixture of a niobium, silicon, and titanium alloy is formed, cast into a shape, and cooled into an ingot. The ingot may then be formed into a medical implant and optionally annealed. Full Article
