Maraging steels are precipitation hardening alloys that can achieve an ultra-high yield strength (~3 GPa), however associated with low toughness. During exposure to high temperatures, oxidation process occurs on the surface of these steels, generally, oxides formed hematite and/or magnetite. The aim this study was investigate a maraging 13Ni15Co10Mo at annealing temperature 900 °C. bulk microst...

Durability is a critical factor for hot stamping dies from an economic point of view. Refurbishing the by depositing new material instead replacement promising method to reduce cost. For this reason, newly developed maraging steel (NMS) was cladded on work tool means directed energy deposition. After optimized tempering, exposures at high temperatures were carried out NMS in order examine softe...

Abstract Injection molding is a cyclic process comprising of cooling phase as the largest part this cycle. Providing efficient in lesser cycle times significant importance industry. Conformal proven technique for reduction injection molding. In study, we have replaced conventional circuit with an optimized conformal tool (mold). The required heat transfer rate, coolant flow rate and diameter ch...

In this work, a new approach for compaction of the gas-atomized 18Ni300 maraging steel at two different temperatures 1050 °C and 1150 using progressive SPS technology is studied. Moreover, influence heat treatments combining solution annealing aging (SAT) simply treatment (AT) on microstructure mechanical properties investigated. It found that samples compacted had higher porosity compared to a...

• Investigation of the directional fatigue behaviour PBF-LM/18Ni300. Proposal a new test methodology for evaluating up- and down-skin fatigue. The is influenced by specimen orientation. Fatigue initiation observed from surfaces. Surfaces metals produced additive manufacturing (AM) are known to be rough populated with defects, this is, in particular, true downward-facing (down-skin) When dealing...
