Abstract:Most dies in the casting industry for injection moulding are machined from the premium-grade H13 tool steel. They provide excellent performance in terms of mechanical properties and service life; however, these dies are characterised by a relatively low thermal conductivity. The tool-and-die industry is interested in depositing a material of a high thermal conductivity onto steel in order to improve the thermal management and productivity. We have explored the possibility of using copper with a new technology. In this study, the microstructure evolution and mechanical properties are discussed using the Laser Engineered Net ShapingTM (LENSTM) technology. For a better understanding of the solidification, the microstructure of a LENS sample was compared with the microstructure of a reference alloy produced with the ingot-casting technology having the same chemical composition of H13-w(Cu) 87.5 %. We carried out light microscopy, scanning electron microscopy, an EDS microchemical analysis, the tensile test and microhardness testing. The results show a successful fabrication of LENS samples; their microstructure is more homogeneous compared to the castings; they show better mechanical properties and represent a good potential for further development and use.

Title:Vpliv tehnologije izdelave na razvoj zlitine H13-w(Cu) 87,5 %
Abstract:V industriji tlačnega litja se za izdelavo matric orodij pogosto uporablja visokokakovostno orodno jeklo H13, ki ima odlične mehanske lastnosti in dolgo trajnostno dobo, vendar je zanj značilna relativno nizka toplotna prevodnost. Orodjarska industrija želi dodati jeklu material z visoko toplotno prevodnostjo za dosego boljše porazdelitve toplote in večje produktivnosti. Z novo tehnologijo, imenovano Laser Engineered Net ShapingTM (LENSTM), smo raziskali možnost uporabe bakra, spremljali razvoj mikrostrukture ter ugotovili mehanske lastnosti. Za boljše razumevanje strjevanja smo primerjali mikrostrukturo vzorca LENS z mikrostrukturo referenčne zlitine z enako kemijsko sestavo H13-w(Cu) 87,5 %, izdelano s tehnologijo litja. Karakterizacija zlitin je potekala s svetlobno mikroskopijo, vrstično elektronsko mikroskopijo, mikrokemično EDS-analizo, z nateznim preizkusom in merjenjem mikrotrdote. Rezultati kažejo uspešno izdelavo vzorcev LENS, katerih mikrostruktura je bolj homogena in ima boljše mehanske lastnosti v primerjavi z odlitki. Tehnologija LENS je dober potencial za nadaljnji razvoj in uporabo v praksi.
