Definitions

the invention relates to a cold work tool with high wear resistance for powder metallurgically produced workpieces and tools with high toughness and Strength.
Cold work steels with high resistance to wear have a structure in their structure a matrix embedded high hard phase content, in particular carbides, which the substantiate high abrasion resistance.
carbides which the substantiate high abrasion resistance.
high toughness and hardness of the material are the carbide formation and the matrix property, in particular their increased strength of importance.
a cold work steel alloy for the powder metallurgical production of parts, especially tools with high toughness and hardness, as well as resistance to Wear and fatigue is described in the Austrian patent application no. Called 587/2001.
Such a chemically composed material can quite high mechanical property values provide quality assurance. Indeed are often at a full through hardening of large workpieces especially at deep hardening temperatures a grain boundary assignment with chromium-containing Mixed carbides are found, whereby the toughness potential of the alloy is not is fully exploitable. In many cases, an increased Material toughness of the product and a simpler Heat treatment technology for this desired.
the invention is based on the object a cold work tool steel with high wear resistance for powder metallurgy produced workpieces and tools with high toughness and strength too create, which even with simple thermal compensation and / or lesser Hardening temperature reaches a desired level of properties.
the advantages achieved by the invention are to be seen in particular in that it by alloying measures or by using the Interaction of the activities controlling the structural transformation and the carbide - forming elements has succeeded, on the one hand the through - hardenability of the Material to increase and on the other hand to achieve a solid solution hardening, even at low curing temperatures a pre-eutectic Carbide precipitation, especially at the grain boundaries is reduced.
Chromium can on the one hand, individually, at least three carbide formations with form different carbon concentrations and is slightly more metallic than metallic Component introduced by substitution in mixed carbides, the chromium content influenced, but on the other hand also significantly the hardness behavior as Acid acceptance, through hardenability, secondary hardness formation of the material. in principle increasing Chomgehalte retard the structural transformation when hardening or increase the Einhärteiefe and thus act in particular with nickel and manganese similar.
the elements are chorm, manganese, nickel and cobalt in the invention Set concentration limits, with the preferred content ranges a Increase of mechanical material values and quality assurance of the material cause.
one or more than one accompanying element has the following concentration values in% by weight: sulfur (S) to 0.03, preferably to 0.025 niobium (Nb) to 0.01, preferably to 0.006 nitrogen (N) to 0.09, preferably to 0.08 aluminum (Al) to 0.05, preferably to 0.04 and / or more than one impurity element has the following concentration values in% by weight: phosphorus (P) max 0.025 oxygen (O) max 0.009
Tab. 1 shows the chemical composition of a cold work steel alloy according to the invention with the designation Leg. K and those of comparative alloys described by Leg. A to Leg. J, can be seen.
Tab. 2 shows the test results, namely the bending strength, the impact bending work and the wear resistance, with the deformed specimens being tempered to the same hardness of 61 HRC.
the pre-load F r was 200 N
the speed to full pre-load was 2 mm / min
the test speed was 5 mm / min.
Fig. 3 the device used for determining the wear resistance of the materials is shown schematically.
Fig. 1 shows in a bar graph the superior bending strength of the leg according to the invention. K, wherein the prior art corresponding comparison materials A to J each have high bending fracture values.
the alloy according to the invention is in the range of the best materials for this type of stress.
the cold work steel composed according to the invention has an outstanding property level with regard to toughness and strength and has a comparable wear resistance in comparison with the best alloys of the prior art.
