Molding machine cylinder and its production method

A molding machine cylinder comprising a lining layer having a structure comprising 20-50% by area of tungsten carbide particles and 1-10% by area of tungsten-based metal carboboride particles in a nickel-based alloy matrix, and containing 1-7.5% by mass of Fe, can be produced by a centrifugal casting method comprising a first step of heating at higher than 1140 C. and lower than 1200 C., and a second step of heating at 1080-1140 C. after melting the raw material powder.

Coinage alloy and processing for making coinage alloy

A coinage alloy for coinage includes nickel present in an amount from 4 wt. % to 11 wt. %, based on a total weight of the coinage alloy; zinc present in an amount from 20 wt. % to 35 wt. %, based on the total weight of the coinage alloy; manganese present in an amount from 3 wt. % to 6 wt. %, based on a total weight of the coinage alloy; copper; an electrical conductivity from 5% International Annealed Copper Standard (IACS) to 6% IACS measured in accordance with ASTM E1004-09 (2009); and a color comprising a yellowness vector b* that is from 6 to 11, based on a CIE L*a*b* color space and determined in accordance with ASTM Standard E308-15 (2015).

Method of speed control for a vehicle

A vehicle is adapted to sense a condition of use in which a maximum speed control speed is reduced. The condition of use may be indicated by a sensor of the vehicle, or selected according to the kind of terrain across which the vehicle is travelling. Selection of terrain type may be manual or automatic, and may enable a selection of sensors appropriate to the terrain type. A vehicle driver may select a speed control speed lower than the permitted maximum.

Thermal barrier-coated Ni alloy component and manufacturing method thereof

A thermal barrier-coated Ni alloy component includes: a substrate made of a Ni alloy containing Al; an intermediate layer formed on a surface of the substrate; and a thermal barrier layer made of a ceramic and formed on a surface of the intermediate layer. The intermediate layer includes a layer, which is formed from a -Ni.sub.3Al phase on the surface on the thermal barrier layer side, and contains Pt.

Titanium-copper-iron alloy and associated thixoforming method

A titanium alloy that includes about 5 to about 33 percent by weight copper, about 1 to about 8 percent by weight iron, and titanium.

Titanium casting product for hot rolling and method for producing the same

Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of stabilizer elements to the surface and melting and resolidifying the surface. An average value of stabilizer element(s) concentration in a range of within 1 mm in depth is higher than stabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.

Metallic foam anode coated with active oxide material

A three-dimensional metallic foam is fabricated with an active oxide material for use as an anode for lithium batteries. The porous metal foam, which can be fabricated by a freeze-casting process, is used as the anode current collector of the lithium battery. The porous metal foam can be heat-treated to form an active oxide material to form on the surface of the metal foam. The oxide material acts as the three-dimensional active material that reacts with lithium ions during charging and discharging.

Coinage alloy and processing for making coinage alloy

A coinage alloy for coinage includes nickel present in an amount from 13 wt. % to 16 wt. %, based on a total weight of the coinage alloy; zinc present in an amount from 25 wt. % to 32 wt. %, based on the total weight of the coinage alloy; manganese present in an amount from 1 wt. % to 4 wt. %, based on a total weight of the coinage alloy; copper; an electrical conductivity from 5% International Annealed Copper Standard (IACS) to 6% IACS; and a color comprising a yellowness vector b* that is from 5 to 10, based on a CIE L*a*b* color space and determined in accordance with ASTM Standard E308-15 (2015).

Multiple piece engine component
