Intermetallic phase selection in dilute Al-Fe-Si alloys [PDF]

, 1996
The DC casting of 1000 series AI-Fe-Si alloys often results in the formation of a defect known as the Fir Tree Zone (FI'Z) caused by variations in the type of binary AI-Fe eutectic intennetallic phase. These include AI3Fe, which is the equilibrium phase,

Strengthening mechanism of lamellar-structured Ti–Ta alloys prepared by powder metallurgy

Journal of Materials Research and Technology, 2022
Titanium-tantalum alloys with lamellar microstructure were fabricated by cold isostatic pressing under 400 MPa and pressure-free sintering at 1600 °C. By such a low-cost powder metallurgy method, the Ti–Ta alloy exhibited the tensile yield strength of ...

Development of α+β-type biomedical Ti–Nb alloys with high oxygen content [PDF]

MATEC Web of Conferences, 2020
Ti-(5–20)Nb-(0.5–1)O alloys (mass%) were investigated for developing low-cost biomedical α+β-type Ti alloy. Ti-(5, 10, 15, 20)Nb-(0.5, 0.75, 1)O alloys (mass%) were arc-melted and forged into bars. The forged alloy bars were heat-treated at 873 to 1373 K

Controlling the interstitial element concentration in Ti-6Al-4V using calciothermic reduction [PDF]

, 2013
The production of Ti-6Al-4V components via powder metallurgy routes is looked upon as an efficient production method that reduces wastage, but leaves finished products with high interstitial oxygen concentrations that do not meet industrial standards ...

Surface segregation of Ti in Fe-Ti alloys.

SHINKU, 1985
The behavior of Ti in Fe-0.29, 0.64 and 1.48 wt%Ti alloys has been investigated using a time-of-flight atom-probe. Ti segregates to the surface when Fe-Ti samples are heated at and above 600°C in vacuum. Enrichment of Ti (includes titanium oxide formation) at the outermost surface layer is 90% at the (110) and (111) planes, 50% at the (211) plane and ...
