Microstructure, tensile strength and wear behaviour of Al–Sc alloy

Interatomic bonds and the tensile anisotropy of trialuminides in the elastic limit: a density functional study for Al3(Sc, Ti, V, Cr)

“…Mainly the compounds with the first three early transition elements (TM = Sc, Ti, V) are of interest for lightweight structural applications. Trialuminides meet several exacting demands like light-weight, low density, good thermal conductivity, high melting point, acceptable low-temperature damage tolerance, sufficient creep resistance, high specific strength and moduli [1][2][3], oxidation resistance, low diffusivity and solubility in aluminium resulting in low coarsening rate at elevated temperature, etc. In many respects, trialuminides are competitive with the currently used Ni-base super-alloys [4].…”

Dry wear behavior of heat treated eutectic al-si alloy

“…Minor additions of titanium, boron and are normally used for grain refinement and strontium is used for the modification of eutectic silicon [12][13][14][15][16][17][18]. Eutectic alloys (A413) [10-13% silicon] are used for pistons, cylinders, blocks and heads of IC engines in automobile and aeronautical industries [18][19][20][21][22][23][24][25][26][27].…”

Adiabatic Shearing Localisation in High Strain Rate Deformation of Al-Sc Alloy

“…[4][5][6] As a result, Al-Sc alloys are used in a wide variety of sports, transportation and aerospace applications. 7,8) In many of these applications, the Al-Sc components are subjected to severe dynamic or impact loads, and exhibit a quite different behaviour to that observed under quasi-static loading conditions. Therefore, in developing Al-Sc components with an enhanced deformation and fracture performance in typical real-world service environments, it is necessary to obtain detailed insights into the strain-rate properties and failure characteristics of Al-Sc alloy under extreme loading conditions; particularly those characterised by a high shear rate.…”
