Traveling Speed

Friction stir welding technique (FSW) has many advantages in terms of tool design, rotational speed and traveling speed, and can be adjusted in a precise manner. It enables heat input into the system to be controlled. In this study, Aluminum powders were compacted at 350,400 and 450 MPa pressure and sintered at 450 oC temperature for 30 minutes in Ar atmosphere. Sintered powder metal parts were joined to each other by FSW at the speed of 1800 rpm and traveling welding speed 200 mm/min under a constant friction force. The results show that the amount of porosity affects the weldability of powder metallurgy (P/M) parts. Furthermore, the porosity and microstructural evolution of the Aluminum also affected the hardness values of the tested materials.

Effects Of Temperature

Diffusion welding is an advanced bonding process in which similar or dissimilar materials can be bonded in solid state. In this study, aluminium composite (5% and 15% WC) powders were compacted at 450 MPa pressure and sintered at 550 oC for 45 minutes in argon atmosphere.and joined each other by diffusion bonding. The bonding temperatures (585 oC, 600 oC, 615 oC) and dwell time (185 min) were chosen for the welding process at constant 20 MPa. It has been observed that these variations on the welding parameter strongly affected the microstructure and the weldability of the materials.

Abstract Ancorsteel 2000 is a water atomized low-alloy powder metal containing Ni, Mo, and Mn and is useful in powder metal parts requiring greater hardenability. In the powder production process used to make Ancorsteel, molten steel is atomized into irregular, homogeneous particles which are then annealed to produce uniform, dependable steel powders. Ancorsteel grades are designed for powder metallurgy parts requiring densities exceeding 6.7 g/cm^3 (0.24 lb/in.^3). This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on powder metal forms.
