Glass transition and physical aging of PLA, PLA/ZnO_r and PLA/ZnO_s nanocomposites The impact of the two types of nanoparticles on the polymer re- laxation phenomena was probed by

The significant increase of the compressive stress and the changes in the mechanical properties hardness and elastic modulus observed at 50% nitrogen concentration in the plasma may be

In order to evaluate the effect of temperature and dynamic strain aging on the fatigue life, simple tensile tests were carried out on the material at 350C, which corresponds to the high

Mean grain size obtained after processing by I-ECAP ~5 lm is comparable with results obtained after conventional ECAP at the same temperature.[10] Grain refinement led to formability

The different works dealing with the influence of aging on the ultimate properties which were achieved on rubber materials Ben Hassine et al., 2014; Colin et al., 2019; Nait Abdelaziz
