The 1300 8 C isothermal section in the Nb – Sn – C ternary phase diagram

In this paper we map out the 1300 8C isothermal section in the Nb–Sn–C ternary system. The results show that the only ternary compound in the system, Nb SnC, is in equilibrium with Sn, NbC , and Nb Sn, but not with Nb, Nb C or C. The Nb SnC phase is not a 2 x 3 2 2 stoichiometric compound but exists over a range of compositions that range from an Nb:Sn:C ratio of |54:22:24 at.%, when in equilib...

The 13001C Isothermal Section in the Ti–In–C Ternary Phase Diagram

In this paper we map out the 13001C isothermal section in the Ti–In–C ternary system. Two ternary compounds exist: Ti2InCa and Ti3InCd. At 13001C TiCx is in equilibrium with all phases, Ti3InCd is in equilibrium with all the phases except C, and Ti2InC is in equilibrium with all phases except Ti and C. The range of d in Ti3InCd varies from 0.95 to 0.8. A correlation was found between d and the ...

Preparation and evaluation of tretinoin microemulsion based on pseudo-ternary phase diagram.

PURPOSE The aim of the present research was to formulate a transparent microemolsion as a topical delivery system for tretinoin for the treatment of acne. METHODS Microemulsion formulations prepared by mixing appropriate amount of surfactant including Tween 80 and Labrasol, co-surfactant such as propylene glycol (PG) and oil phase including isopropyl myristate - transcutol P (10:1 ratio). The...

Thermal stability and phase transformations of martensitic Ti–Nb alloys

Aiming at understanding the governing microstructural phenomena during heat treatments of Ni-free Ti-based shape memory materials for biomedical applications, a series of Ti-Nb alloys with Nb concentrations up to 29 wt% was produced by cold-crucible casting, followed by homogenization treatment and water quenching. Despite the large amount of literature available concerning the thermal stabilit...
