“…Hence, it is predestined to serve as the outer layer of a functionally graded material. The MARLOK material is characterized by excellent fracture toughness, good strength at elevated temperatures and a good weldability [8]. In respect of its high fracture toughness, this material serves as the buffer layer between the top layers of DIEVAR and the base material (AISI H11).…”

The lifetime and economic methods of improving the lifetime of a die-casting die are key factors for the die-casting industry since the global competition and the competition with other production techniques have increased significantly. The article depicts the approach, technical realization, latest results and process limitations of the INNOGRAD research project. Here, powder-based laser-cladding is applied to combine two materials as a functionally graded material. By applying gradient structures it is possible to fit the material to the predominant type of exposure, resulting in an increase in the lifetime of die-casting dies.

“…[6] Because of the low carbon content, maraging steels have good machinability. [7] They have higher modulus of elasticity, lower thermal expansion coefficient, high strength, moderate toughness, and good weldability as compared with conventional alloy steels. [8] Another important property is its high thermal conductivity, which reduces surface temperature during thermal loading and lowers thermal stresses.…”

a centre of excellence for research in engineering Materials, Advanced Manufacturing institute, King saud University, riyadh, saudi Arabia; b steel technology department, central Metallurgical r&d institute (cMrdi), helwan, egypt ABSTRACTThe corrosion resistance behaviour of newly developed M-23 and M-29 grades cobalt-free maraging steel over conventional C-250 maraging steel was investigated at ambient temperature in 1 M H 2 SO 4 solution using linear polarisation and electrochemical impedance spectroscopy (EIS) techniques. To reveal the corrosion resistance performance, some significant characterisation parameters from linear polarisation and EIS curves were analysed and compared. The results show that the corrosion resistance of the M-23 and M-29 cobalt-free maraging steel is more than the conventional C-250 maraging steel in acid solutions at ambient temperature.

“…Additionally, small quantities of Ti and Al (0.05-0.5% and 0.05-0.15%, respectively), further contribute to intermetallic phases to be precipitated [12]. These alloys find their applications in military [13,14], aircraft [15], aerospace [16,17] and die-casting and tooling industries [18,19].…”

The mechanical behaviour of as-built DED-produced 18Ni300 Maraging steel was studied by manufacturing a wall-like structure from which three different specimen types were obtained: specimens in which the loading direction was the same as the printing direction (vertical), specimens in which these two directions were perpendicular (horizontal), and bimetallic specimens in which the interface between the AISI 1045 substrate and the 18Ni300 steel was tested. The yield strength of the produced samples was 987.9±34.2, 925.9±89.7 and 486.7±47.2MPa for the vertical, horizontal and bimetallic specimens, respectively, while the elongation to failure was 9.4±1.9, 18.3±2.3 and 14.06±0.6% in the same order. The latter specimen failed within the substrate-comprised portion of the specimen. Additionally, the fracture surfaces were analysed through scanning electron microscopy, concluding that while both surfaces consist of dimples, the horizontal specimen presented microporosities with a reduced diameter. A microhardness analysis in the printed wall-like structure following the printing direction yielded an average hardness of 392±21 HV0.3, with fluctuations along the build direction mostly within one standard deviation.
