Microstructural and XRD Analysis and Study of the Properties of the System Ti-TiAl-B4C Processed under Different Operational Conditions

“…In general, with B 4 C particles at the lowest temperature (900 • C), the density of the specimens made from TiAl* presents lower values (3.400 g/cm 3 at 40 MPa and 3.497 g/cm 3 at 80 MPa) than the other specimens from Ti-Al blend powder (3.530 g/cm 3 at 40 MPa and 3.606 g/cm 3 at 80 MPa). This is in agreement with microstructures observed in Figure 6.…”

“…In the specimens manufactured without B4C, if the temperature is rising from 900 °C to 1000 °C under 40 MPa, then the density of the specimens made from TiAl* increases by only 0.2% (4.364 and 4.374 g/cm 3 , respectively) and for specimens from the Ti-Al blend, this increase is 0.7% (4.371 and 4.339 g/cm 3 , respectively). These increments are negligible values.…”

“…While evaluating the influence of the consolidation pressure at the same constant manufacturing temperature (1200 • C) for each type of powder, the increment in pressure from 40 MPa to 80 MPa involves increases in percentages of 2.7% (3.724 and 3.826 g/cm 3 , respectively) when TiAl* prealloyed powder is used and 1.4% (3.710 and 3.763 g/cm 3 , respectively) for Ti-Al blend powder.…”

“…Among the different types of reinforcement materials employed to produce TMCs, recent studies present several ceramic materials (TiB, TiB 2 , and TiC) as suitable candidates due to their high elastic modulus and hardness, similar thermal expansion coefficients, and density with the titanium matrix [3][4][5][6]. The in situ synthesis technology constitutes one of the most promising approaches towards fabricating the particulate-reinforced titanium-based composite with mechanical properties elevated by the hard phases formed in situ [7][8][9].…”

Investigation on the Wear Properties of Ti/TiC/TiN Composite Coatings Prepared by Powder Cored Wires Through TIG Method at Nitrogen Atmosphere on Titanium Substrate

“…Ceramic powders-filled core wires have been used to improve surface properties such as hardness, wear and corrosion resistant, anti-erosion and other performance coatings by Tungsten Inert Gas (TIG) procedure 3,20 . In comparison to other fabricated procedures, TIG process has advantages such as uniform distribution of reinforcement finer reinforcement particle size and clear interface 21,22 .…”
