A method for forming a vehicular brake rotor involving loading a shaped metal substrate with a mixture of metal alloying components and ceramic particles in a dieheating the contents of the die while applying pressure to melt at least one of the metal components of the alloying mixture whereby to densify the contents of the die and form a ceramic particle-containing metal matrix composite coating on the metallic substrate; and cooling the resulting coated product.

The method comprises at least the following steps: exposing a substrate to focused laser irradiation at a preselected series of locations that trace a subset of the substrate volume that is connected to the surface of the substrate; some subsets of substrate volume not connected to the surface of the substrate may also be exposed at the same time for other purposes, for instance, so that they can be used as waveguides or other optical elements or for another subsequent etching step; removing the substrate material from the exposed preselected series of locations to create within the substrate at least one cavity that is connected to the surface of the substrate; immersing the cavity-containing substrate in an appropriate atmosphere such as a selected gas or vacuum and, within this atmosphere, contacting the substrate surface with the molten castable material surface at locations where the cavity or cavities emerges from the substrate; applying pressure to the castable material to cause it to infiltrate the substrate cavities; and solidifying the castable material within the cavities.

This invention relates to a process for controlling a dental firing furnace in which a temperature in a firing chamber of the dental furnace is detected by means of a temperature sensor, and in which a heating element that is controlled by a control device controls the heating of the firing chamber of the dental firing furnace based on the measurement result of the temperature sensor. In this process a dental restoration part is received within the firing chamber of the dental furnace. The heating is controlled so that the dental restoration part reacts exothermically, emitting additional heat. The additional heat is detected by the temperature sensor which is pointed at the dental restoration part and the control device delivers at least one signal representing the additional heat, such as in the form of a display signal and/or control signal.

This invention pertains to plastic injection mold tooling, and also large forgings, formed from a low carbon mold steel having markedly increased hardening and hardenability properties in large sections as contrasted to currently available commercial products. The above attributes are obtained together with equal or better machinability and improved mold parting line wear. When manufactured in conjunction with a double melt process, this invention can improve significantly polishing characteristics and other attributes of molded parts in tooling sets.

There is provided a copper-titanium alloy with large fluctuations in Ti concentration. The copper-titanium alloy for electronic components contains 2.0 to 4.0% by mass of Ti and, as a third element, 0 to 0.5% by mass in total of one or more selected from a group consisting of Fe, Co, Mg, Si, Ni, Cr, Zr, Mo, V, Nb, Mn, B, and P, with a balance being copper and unavoidable impurities, wherein when crystal grains having <100> orientation in a section parallel to a rolling direction are subjected to area analysis of Ti concentration in a matrix phase, a difference between a maximum Ti concentration and a minimum Ti concentration is 5 to 16% by mass.
