Effect on Surface Properties of H13 Mold Steel Cladding Layer by Scanning Strategy
نویسندگان
چکیده
Laser cladding technology is used to clad the surface layer of H13 mold steel with Ni60A metal powder coating solve failure problem. The study JMatPro software extract and fit thermophysical property parameters substrate material, then ANSYS APDL qualitatively analyze distribution melt pool morphology, nodal temperature versus time course curve residual stress magnitude during laser process. Based on results minimum in cladding, reasonable scan paths were derived for preparation coatings die steel. show that maximum peak process 2515°C using short path scanning. can form a good metallurgical bond at this temperature, 406.68 MPa scanning direction 284.45 perpendicular direction, which significantly smaller than stresses other methods. values different strategies are from largest smallest: spiral > block long scan.

متن کاملNickel-based Superalloy Layer Deposited on AISI H13 Hot Tool Steel Base Metal Using Explosion Cladding process
An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...
متن کاملSuperplasticity of Annealed H13 Steel
H13 steel is a widely used hot work die material. A new type of hot working method is imperative to develop complex and precise dies. In this paper, the heat treatment of H13 steel (AISI) was carried out by annealing, the final structure is a point or spherical pearlite, and the grain size is about 30-40 μm. The tensile properties of the annealed microstructure were investigated at 650, 750, an...
