Dual-phase ADI material microstructure consists of different amounts and morphologies ausferrite free ferrite, obtained by subjecting ductile iron to specific heat treatment. Its strength is lower compared comparable materials but exhibits a higher ductility, the major disadvantage ADI. In current study, an unalloyed was intercritical austenitized in two-phase regions (?+?) at four temperatures...

Although overlay coatings deposited via plasma transferred arc welding (PTAW) can effectively prolong the service life and improve performance of components, cracks pores tend to occur in high-hardness wear-resistant coating during deposition process. Further treatment is thus necessary quality. Herein, PTAW-deposited Ni-based was remelted using (PTA) under different remelting currents (RCs). T...

Electric vehicle battery systems are made up of a variety different materials, each system contains hundreds batteries. There many parts that need to be connected in the system, and welding is often most effective reliable connection method. Laser has advantages non-contact, high energy density, accurate heat input control, easy automation, which considered ideal choice for electric manufacturi...

Clad rebars of four different base materials (20MnSiV, 35# steel, 45# and 55# steel) were successfully produced by a vacuum hot rolling process. A metallographic optical microscope (OM), electron backscatter diffractometer (EBSD), probe micro-analyzer (EPMA), salt spray corrosion chamber used to investigate the clad contour, properties, composite interface microstructure all rebars. The results...

Malleable cast iron is one of the irons that has excellent forging properties. result heat treatment white iron, so cementite decomposed to form graphite in rosettes. often used for tooling and on railway components. Testing determine fatigue limit malleable very important it can find out maximum load receive. Fatigue testing was carried with variations loading angles 1o, 2o, 3o, 4o 5o. From te...

To obtain excellent mechanical properties from large cross-sections of plastic mould steel (SDP1), we conducted multi-directional forging (MDF) to control the microstructure ingots. investigate microstructural evolution SDP1 during MDF, performed hot at 1150 °C using a THP01–500A hydraulic press. The dimensions specimens were Φ38 mm × 80 mm. after was observed under metallographic microscope. F...
