The demand of economic processes concerning manufacturing technology,cycle time and material properties has led to the development of near net-shape techniques.Precision forging is a well-known manufacturing technology to achieve high output rates.An approach of optimization concerning the part material to produce load-adapted material properties is the so-called compound-forging.Therefore,two different alloys with adjusted material properties are forge-welded together during the forging operation.For example non-tempering and tempering steels are used to compound-forge gears with a hard and wear-resistant surface layer on the one hand and a ductile bulk material on the other hand.This process does not require a time consuming case hardening operation.Compound-forging of steel materials during a forging operation is possible due to the high temperatures of the raw parts and the high pressure during the forming process.Compound-forging was developed to forge spur gears and shall now be introduced to manufacture helical gears and shafts.For the production of gears and shafts billets made from non-tempering steels are forge-welded together with billets consisting of tempering steels by precision forging as well as indirect impact extrusion.In this paper the comparison of the material properties of compound-forged gear wheels and shafts with a hard and wear resistant surface layer and a ductile bulk material is given.Mechanical properties as well as the micro-structure of the parts were investigated.The results of the investigations show a load-adapted material distribution of forge-welded materials for the production of gears and shafts.For both geometries the strength of the compound-material is as high as the strength of the weak material if at least one of the forge-welded parts is made of tempering steels although the elongation at fracture is reduced.
