設計を補完するために高める必要がある。Due to current development goals in internal combustion engine construction, which seek to increase the ignition pressure and thermal insulation of the combustion chamber in order to reduce fuel consumption and pollutant emissions, the aluminum-based lightweight materials used have a significant impact. Therefore, its load-bearing capacity needs to be increased to complement the structural design.

Aluminum-silicon alloys reinforced with fibers, carbon, steel, etc. or whiskers, such as SiC, have a relatively high resistance to mechanical and thermal loads. Pressure casting methods are extremely suitable for the production of such fiber-containing composite materials (Bader, M.G.: Alus-ina

かかる。Ceramic materials can be expected to have extremely high temperature resistance and more favorable corrosion resistance behavior. However, mass production of complex ceramic components, such as monolithic pistons or turbine blades, remains an open problem. Moreover, the potential use of ceramics in internal combustion engines is inherently limited because ceramics are extremely sensitive to notches, mechanical shocks, and thermal cycling loads. Additionally, ceramics add undesirable weight, cannot be molded without considerable expense, and are also fairly expensive to manufacture.

ある。Materials consisting of intermetallic phases have in themselves the properties of metals and ceramics; for example, they have good heat conductivity, high melting temperatures and, if appropriate, satisfactory ductility. This material is therefore clearly suited to fill the gap between traditional aluminum-based lightweight metal materials and high-temperature resistant but brittle ceramics. This is particularly relevant for gas turbines and internal combustion engines, where improved materials can increase operating temperatures and therefore thermal efficiency.

It has been used in lightweight metal pistons made of aluminum-silicon alloys insofar as they are mixed with nickel or copper materials. The hard intermetallic phase and some silicon are embedded in a matrix of highly supersaturated aluminum crystalline solid solution, resulting in high wear resistance (US-A-4,562,327).

The optimum composition of this alloy is defined by the eutectic part, the pseudo-binary part, and the part surrounded by 42% by weight of aluminum in the phase diagram of the aluminum-magnesium-silicon ternary system. The disadvantage of such lightweight casting materials is that porosity is not always avoided, and this porosity occurs when the residual melt in the casting solidifies, and the melt that is liberated during solidification as the solubility decreases. produced by gases dissolved in
