In uniform strain region which equals to ~20 % the steel remained non-magnetic austenitic steel, and only after fracture strain point (El=26 %) a small amount of ferromagnetic phase was discovered in necking region only, using magnetic method (Table 4).
On the one hand, at -163 °С steels have rather high ductility: El=26 %, ψ= 70 % for stable austenitic steel Cr18Ni5Mn9Мo2N (6) and El=39 %, ψ=78 % for steel Cr18Ni10N (5) – due to trip-effect.

The negative influence on the mechanical properties of bamboo due to removal of the outer skin as well as the considerable material wasted as a result has been reported by Nakajima et al. [4] and Tanaka et al
Cherdchim et al. [12] studied the thermal softening of black-sweet bamboo culms in linseed oil and produced flat sheets after applying load.

Review: Effect of Alloying Element on Al-Si Alloys M.N.
Introduction Al-Si cast alloys contribute to 85-90 % of aluminium (Al) casting products.
Fe is a deleterious impurity presence in Al-Si alloys as it dissolves readily in Al and forms brittle intermetallics.
In Al-Si9 Cu X series, increasing Cu level (from 0 to 4 wt. %) in Al-Si9 Cu X series leads to increasing YS and hardness.
Seifeddine et al. [4] noted that the strength of the Mn added Al- 9% Si increases gradually with an expense on ductility.

Ifeanyi Anthony Anyanwu el al concluded that in the peak aged Mg-Gd-Y-Zr alloys, β'' and β' phases coexist and both precipitates contribute to age hardening [7]. 3.3 tensile properties of extruded specimens Figure 4 shows the tensile properties and elongation of the investigated extruded alloys aged at 225°C.

Morphological aspects of MM-ed HAP powder particles: c) after 10 hours Chemical composition Our research confirms the mechanisms of wet MM set by El Briak-Ben Abdeslam et al. [22]: the liquid presence in the milling vial “cleans” the interface between the milling balls during the mutual collision and thus, the contamination phenomenon occurs.
