Effects of pre-sintering on microstructure and properties of TiBw/Ti6Al4V composites fabricated by hot extrusion with steel cup

Optimization of borosilicate glass/CaTiO3‐TiO2 composite via altering prefiring temperature and particle size

“…Whereas, with the decrease in ceramic particle size, the dissolubility of ceramic in glass liquid phase was enhanced and the wettability between glass liquid and ceramic was improved. But the increased specific surface area made it need more glass liquid phases to be wrapped . For the ceramics with particle size ranging from 2.93 to 4.54 μm, they achieved densification at 875°C.…”

“…Thereby, glass liquid phase in 850°C was enough to achieve sintering densification. But with the increase in the sintering temperature, the pores in the composites would erupt out by the driving of the high temperature resulting in a lower density . Whereas, with the decrease in ceramic particle size, the dissolubility of ceramic in glass liquid phase was enhanced and the wettability between glass liquid and ceramic was improved.…”

Effect of extrusion dies angle on the microstructure and properties of (TiB+TiC)/Ti6Al4V in situ titanium matrix composite

“…4c). The increasing of the strength can be mainly attributed to the matrix work hardening including the formation of high dislocation density, dynamic recrystallization and grain refinement [4]. Table 2 lists the tensile properties' value of the original and extruded (TiCþTiB)/Ti6Al4V composite.…”

“…Last several decades, single reinforced metal matrix composites have been studied focus on the high strength, corrosion resistance, high damage tolerance, etc. [3,4]. Nowadays, technological developments have been performed in order to improve the comprehensive properties by replacing single reinforced composites with reinforcing structural materials with more than one type of reinforcements for aerospace field using improved low cost production routes [5,6].…”

A Novel Extrusion for Manufacturing TiBw/Ti6Al4V Composite Tubes with a Quasi-Continuous Reinforced Structure

“…Thus, it is necessary to explore a novel process to produce TiBw/Ti6Al4V composite tubes. Inspired by traditional canning extrusion [ 9 , 25 ], hot extrusion with a filler material was attempted to produce the TiBw/Ti6Al4V composite tubes. Compared with the conventional extrusion process, this process has the advantage in the fabrication of thin tubes with a large length-diameter ratio, which skips the requirement of the rigid spindle.…”
