Hot Extrusion of Ceramics

Two dense ceramics, Bi 2 Sr 2 CaCu 2 O 8+X and 2Y‐TZP: 10 wt% Al 2 O 3, were hot‐extruded through conical dies under a wide range of conditions.Extrusion of Bi 2 Sr 2 CaCu 2 O 8+X was performed at 775 to 825 C and speeds of 0.0005 to 0.2 mm/s, with the die semi‐angles from 30 to 60 and extrusion ratios from 4 to 9.

Extrusion and injection molding of ceramic micro and

Ceramic injection molding (CIM) has become a standard process in the ceramics industry in the last 20 years. Components such as alumina inserts for water taps or water pump seals have become affordable since they are being produced in millions of pieces. High performance ceramics with submicron or even nanoscale structural features are well known from material science. Due to the difficult

Extrusion of metals by Hariprasad

Hot extrusion Hot extrusion is done at fairly high temperatures approximately 50 to 75 % of the melting point of the metal. • The pressures can range from 35-700 MPa • The most commonly used extrusion process is the hot direct process. • The cross-sectional

Tailoring the mechanical and degradation performance of

A novel Mg-2.0Zn-0.5Ca-0.4Mn alloy has been formulated and processed through melt spinning and hot extrusion to enhance its mechanical and degradation properties. Microstructural characterization of rapidly solidified alloy ribbons consolidated by extrusion revealed a fine and fully recrystallized microstructure with average size of 4 m. The conventionally extruded alloy consisted of several
