Abstract: The invention relates to a method consisting of the steps of providing a pre-alloyed iron-based metal powder comprising at least 1.3-3.5% chromium, 0.15-0.7% molybdenum, manganese and unavoidable impurities, mixing said powder with 0.1-1.0% graphite, compacting the obtained mixture at a pressure of at least 600 MPa, sintering the compacted part in a single step at a temperature above 1100° C., shot-peening the part and after sintering optionally hardening the component. The invention also relates to a powder metallurgical part and use of a low chromium prealloyed powder for preparing notched sintered parts having a bending fatigue limit of at least 340 MPa at a sintered density of 7.15 g/cm3, preferably at least 400 MPa at a sintered density of 7.3 g/cm3.

Abstract: Thin automobile components, such as a transmission case made of an aluminum alloy, are provided which are less likely to create vibration-derived noise. An aluminum alloy member, with an insert provided therein, possessing improved damping capacity, comprising: an austempered graphite cast iron member inserted into an aluminum alloy with the thickness of a section constituting a product being not more than 6 mm. A process for producing an aluminum alloy member, with an insert provided therein, wherein cooling is performed so as for the temperature of a graphite cast iron material to reach 400.degree. C. or below within 10 sec after pouring of an aluminum alloy. The graphite cast iron material comprises by weight 2.5 to 4.0% of carbon, 2.0 to 3.5% of silicon, 0.1 to 0.8% of manganese, and at least one member selected from the group consisting of 0.1 to 2.0% of copper, 0.1 to 2.0% of nickel, and 0.05 to 0.5% of molybdenum with the balance consisting of iron and unavoidable impurities.
