摘要：

The specimens prepared by casting with pressure crystallization of standard Al alloy (%: 11.8Si, 2Cu, 1.2Mg, 0.8Ni, 0.4Mn, 0.7Fe, 0.1Ti) and elaborated Al alloy, containing 11-13 or 17-19%Si, up to 1%Fe and 0.3%Zn as well as Cu, Mg, Ni, Mn, Ti, are used in hardness determination after heat treatment (quenching, cold water cooling, aging). The results show that the elaborated alloy possesses high hardness at 200-350°C. This alloy can be used in manufacturing the pistons and parts undergone to affecting high temperatures and stresses.
