Based on the hot-pressing sintering process, kinetics of crystal grain growth and densification kinetics, mixing ratio raw material powder system are designed. The pressure is maintained at 30 MPa from temperature rise to end wait until reaches corresponding hot pressing (1200°C~1400°C), keep time for 1.5h~4.5h, stop heating depressurize, alloy billet cooled room with furnace. main phases Ti2Al...

Controlling the formation of noncompact second phase particles during direct chill (DC) casting aluminium alloys with grain refiner addition remains challenging, as it results in energy intensive homogenisation and deformation problems. In this work, we employed a novel strategy DC A6082 alloy to produce billets fine-scale dispersion particles. The involves maintaining 2–7 °C above liquidus the...

Elastic-plastic finite-element analysis applied to metalforming allows the real macroscopic properties of the workpiece to be incorporated. This paper presents the results of an experimental study of the initiation of cracking in side-pressing of a heat-treated aluminium alloy (Duralloy 2014). Using an F. E. analysis, these are related to various fracture criteria. It is found that the criterio...

Ceramic industrial kiln refers to the combustion equipment for ceramic production, which generally roller kiln, shuttle tunnel and kiln. Roller with continuous firing rotating as vehicle of billet body; Tunnel adopts takes rail car transport body. Shuttle is fired intermittently consists car, chamber door. Factors influencing energy saving include construction materials, structure, technology, ...

Substantial quantities of senile coconut palms are present in plantations within the Asia-Pacific region. Once coconut palms become over-mature, their production of traditional products, such as coconuts, significantly decreases, resulting in profitability challenges for farmers. Presently, few profitable markets exist for over-mature, senile coconut palms. Using the coconut palm stem in compos...
