“…[8][9][10] As ductility may improve if instead of tetragonal TiAl 3 (D0 22 ) or ZrAl 3 (D0 23 ) metastable (Ti,Zr)Al 3 with cubic L1 2 structure forms, quite some effort has been spent on establishing phase stability in the Al-rich part of the system. [11][12][13][14][15][16][17] With the industrialisation of c TiAl based alloys, phase equilibria among the Ti-Al based phases in this system came into focus. [18][19][20][21][22][23] While all these activities were limited to specific parts of the system, studies of full isothermal sections have been performed only very recently.…”

Only within the last couple of years, complete isothermal sections for the Al-Ti-Zr system have been determined. Up to then there had been several investigations, but these were limited to the Ti-Zr and Ti-Al sides and the Ti- and Al corners of the system. Also recently the system has been evaluated by thermodynamic ab initio calculations and CALPHAD-type (CALculation of PHAse Diagrams) modelling. As Al-Ti-Zr alloys are of interest for a variety of applications and as the last assessment has been performed more than 15 years ago, this new critical evaluation of the existing literature about phase equilibria in the Al-Ti-Zr system has been performed.

“…Their initial melting point is higher than that of Ni-Al alloys [4]. The most effective way to control the structure of aluminum (nickel) alloys is to introduce small amounts of transition metals (TM) as additions to binary [5][6][7][8][9][10] and multicomponent [11][12][13][14][15][16][17][18][19] master alloys: Al-TM (Ti, Zr, Sc, Hf, etc.) and Al-Sc-Zr; Al-Zr-Ti; Al-Sc-Ti; etc.…”

This paper deals with the investigation of complex-alloyed nickel aluminides obtained from oxide compounds by aluminothermic reduction. The aim of the work was to study and develop the physicochemical basis for obtaining complex-alloyed nickel aluminides and their application for enhancing the properties of coatings made by electrospark deposition (ESD) on steel castings, as well as their use as grain refiners for tin bronze. The peculiarities of microstructure formation of master alloys based on the Al-TM (transition metal) system were studied using optical, electronic scanning microscopy and X-ray spectral microanalysis. There were regularities found in the formation of structural components of aluminum alloys (
