Reviewing the class of Al-rich Ti-Al alloys: modeling high temperature plastic anisotropy and asymmetry
In the last decades, the class of Ti-rich TiAl-based intermetallic materials has replaced many contemporary alloys till 900 °C. Due to higher oxidation resistance, 20% lower density and higher (about 150 °C more) operating temperature possibility of Al-rich TiAl alloys over Ti-rich side, phases from the Al-rich region of this alloy system are considered to be highly potential candidates for hig...
متن کاملMechanical Alloys in The Al-rich Part of the Al-Ti Binary System
Aluminum is commonly used as fuel additive for propellants, incendiaries, and explosives. The main limitation to its use lies in comparatively slow ignition and oxidation/combustion kinetics. Performance can be significantly improved if pure aluminum is substituted by thermodynamically less stable alloys. In this context, mechanical alloys in the aluminum-rich section of the Al-Ti binary system...
متن کاملSlip Resistance of Ti-Based High-Temperature Shape Memory Alloys
Titanium with Nb, Zr, and Ta alloying substitutions possesses high plastic slip resistance and high transformation strains upon bcc (b) to orthorhombic ða00Þ transformation. In the current study, we determine the critical resolved shear stress (CRSS) for slip in Ti alloyed for a wide composition range of Nb, Ta, and Zr. The CRSS is obtained with a proposed Peierls–Nabarro formalism incorporatin...
متن کاملDIFFICULTIES IN GRAIN REFINING ALUMINUM LITHIUM ALLOYS USING COMMERCIAL Al-Ti AND Al-Ti-Bor MASTER ALLOYS
High strength aluminum alloys, especially those containing zirconium, are historically difficult to grain refine. Early efforts by Alcoa indicated that the addition of lithium to these alloys increases difficulty with grain refinement. Although grain refining of alloys 2090 and 2091 was possible, consistent results were not obtained. Statistically-designed experiments were used to quickly ident...
متن کاملthe role of thematic structure in comprehending spoken language
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
