Suitability assessment of replacement of conventional hot-working steels with maraging steel. Part 1, Mechanical properties of maraging steel after precipitation hardening treatmentGrum, Janez ; Zupančič, Martin, 1965-The paper deals with the results of measurement of mechanical properties of maraging steel Thyssen 1.2799 after precipitation annealing with a wide spectrum of temperature/time conditions. The ... purpose of the investigation conducted on the material for die-casting tools was to find out how the tool life could be extended depending on the heat-treatment conditions and the microstructure of the steel. Thus the influence of temperature/time conditions of precipitation annealing on tensile strength, hardness, and impact toughness of the steel was studied. The Charpy impact toughness test was carried out at a temperature of 200°C, which is, according to our assessment, an average operating temperature of the observed tool surface in die casting of aluminium alloys. Measurements of the mechanical properties were accomplished on three test pieces under each combination of annealing conditions. Special attention was paid to the correlation of the mechanical properties measured under individual participation annealing conditions.Source: Zeitschrift für Metallkunde : international journal of materials research. - ISSN 0044-3093 (Bd. 93, Hf. 2, 2002, str. 164-170)Type of material - article, component partPublish date - 2002Language - englishCOBISS.SI-ID - 5055515
