In this paper, the behavior of energy absorption of crush-boxes, made of Aluminum foam advanced material, was investigated based on foam cellular structure homogeneity. Therefore, thin-walled tubes of Cu-Zn30wt.%.brass alloy with 27 mm diameter and 1 mm thickness were filled with A356-10vol.%SiC-Xwt.%. of TiH2 foam liquid. Foam samples with 1, 1.5, 2wt.%. of TiH2 were prepared by Form Grip into...
The state of the art of conversion reactions of metal hydrides (MH) with lithium is presented and discussed in this review with regard to the use of these hydrides as anode materials for lithium-ion batteries. A focus on the gravimetric and volumetric storage capacities for different examples from binary, ternary and complex hydrides is presented, with a comparison between thermodynamic predict...
Calculations using first principles methods and strong coupling theory are carried out to understand the electronic structure and superconductivity in cubic and tetragonal TiH2. A large electronic density of states at the Fermi level in the cubic phase arises from Ti-t2g states and leads to a structural instability towards tetragonal distortion at low temperatures. However, constraining the in-...
Thermoreversible gelcasting, a near-net-shape processing technique, is demonstrated here for titanium. The gelcasting system is composed of TiH2 particles suspended in a triblock copolymer gel that behaves as a viscous liquid above 56 C and an elastic solid at room temperature, a temperature-dependent transition that is fully reversible when solvent is present. Organic pyrolysis to remove the g...
ورق های فوم آلومینیمی تولید شده با استفاده از فرآیند اتصال نوردی تجمعی دارای پتانسیل بالایی به منظور ساخت سازه های ساندویچی حاوی هسته از جنس فوم فلزی می باشند. طراحی جامع و همه جانبه ی این سازه ها نیازمند بهینه سازی فراسنج های فوم سازی، بویژه عملیات حرارتی فوم سازی است که موضوع اصلی این پژوهش نیز می باشد. استفاده از کوره های پیش گرم شده به عنوان جایگزینی برای کوره های مادون قرمز (که قابلیت تولی...
In this study pure Al and pre-alloyed Al alloy powders (Alumix 231Al-Cu %2.5-Mg %0.5–Si %14) with or without reinforcing elements were used to produce classical Al foam or spherical Al foam with various production parameters by using powder metallurgy route and the results obtained have been discussed. Al2O3 and SiC particles were used as reinforcing elements and TiH2 powders were used as foami...
