Customer demands are driving steel producers to develop steels that exhibit better low temperature toughness to resist brittle fracture in the structure, sustain higher loads per unit area in earthquake and hurricane zone areas, demonstrate improved fire-resistant properties and provide for improved weldability to assure defect-free welded joints.
Achievement of these enhanced properties can only be realized through the development of an appropriate steel chemistry with the proper melting and hot rolling practices to successfully obtain a fine grain homogeneous microstructure.
This effect of Nb on microstructure (bainitic and acicular ferrite fine grain) evolution and the new Nb bearing structural steels has been developed by several global steel producers for grades at yield strengths of 460MPa and above heavy plates with exceptionally high toughness, excellent arrestability and large heat input weldability for hull structures of mega-container ships.
A third application is for high performance steels for bridge structures requiring high yield strength, ductility and good weldability.

Figure 1 Chemical structure of CR-39 polymer sample It is known that the interaction of radiation with polymers destroys their initial structure by cross-linking, scission and emission of atoms, molecules and molecular fragments.
This can be attributed to interaction of radiation with polymer and destroys their initial structure with formation of free radical.

Introduction Unique properties of porous silicon together with easy control over the parameters of porous structure make this material very promising for practical applications in optoelectronics and photonics [1,2], sensor systems [3,4], biotechnology, medicine [5,6] and a number of other fields [7-11].
It is shown that when i ≤ 8 µm the areas of RPS contain no so-called irregular pores, i.e. pores breaking the regular structure.
SEM photographs of regular pore structures in silicon with periods: a) i = 3 µm, b) i = 10 µm, c) i = 15 µm, as well as the pore channel openings in the shape of: d) triangles (i ≤ 5 µm), e) squares (5 µm ≤ i ≤ 10 µm), f) crosses (8 µm ≤ i ≤ 15 µm) and g) snowflake-like crosses (i = 15 µm) Thus, at N = 1.25×1015 cm-3 in KEF-4.5 silicon samples the optimum value of areal density of the pores ρopt for RPS generation is 0.125 µm-2.
