SMART-RIm: Simulation Methods Assuring Reliable Technology for Resorbable load-bearing Implants in this repository: Experimaental data of static tensile tests and reverse loading tests on three different magnesium alloys Authors: Dirk Steglich, Jan Bohlen, Björn Wiese Affiliation: Helmholtz-Zentrum Hereon License: CC0 1.0 Universal as received materials: Exrturded rods, 6 mm diameter, circular cross section, cut into 1000 mm sections (100 - 700), testing along axial direction alloys: in wt.% Mg-2Gd Gd Mn Al Be Ca Co Cu Cr Fe Ni Si 1,7883 0,0238 0,0195 <8.5e-7 0,0042 <4.5e-7 0,0008 0,0002 0,0035 <3.3e-7 0,0068 0,0656 0,0007 0,0051 - 0,0008 - 0,0000 0,0000 0,0011 - 0,0019 Mg-4Y Gd Ni Y Nd Fe Cu Si Be 0,10 <0.015 0,65 0,00 0,0004 0,0005 0,0025 0,0001 ZX10 Magnesium 98.91%wt, Zinc 0.94%wt and Calcium 0.15%wt. T samples - static tensile tests: round bars according to DIN 50125, d_0=4 mm, L_0=24 mm, M6 threads, mechanical extensiometer to trace displacement, tensile test machine Z050 (ZwickRoell GmbH & Co. KG) samples - load reversal tests - tension - compression - tension & compression - tension - compression - tension: round bars with reduced parallel length, d_0=5 mm, L_0=7 mm, pressure clamping, video extensometer used to acquire the stain, load reversal once +-5% of engineering strain is achieved; final tensile sequence until final failure of the sample test conditions: temperature 20°C, prescribed traverse speed of +- 0.5 mm/min, resulting in a local strain rate of +- 10-3 /s Bonus data: - an estimate of the strength differential effect, quantified by initial yield ratio of tensile and compressive stresses (the latter not validated part of these data) - A fit based on combined istropic-kinematic hardening and the CPB2008 Yield function for each material.
