Using the microwaves energy, new polymers were synthesized by radicalic polymerization for anticorrosive and antiscaling protection of industrial cooling water systems.
Experimental study of the post-fire mechanical properties Apr 01, 2020 · Choi and Chung studied the post-fire mechanical properties of SN400 (234 MPa), SM520 (355 MPa) and SM570 (440 MPa) steel and determined that these steels could regain some of their initial properties upon cooling, but the I.R. Choi, K.S. ChungResidual strength of structural steels:SN400 SM520 and SM570.
However, in providing this residual strength and stiffness, the bolted web connections can themselves be subject to failures. These include fracturing of the welds of the shear plate to the column, fracturing of supplemental welds to the beam web, or fracturing through the weak section of shear plate aligning with the bolt holes (Figure 1-5).

Post-fire mechanical behavior of ASTM A572 steels Jul 15, 2019 · The change observed in yield strength of test specimens is quantified in terms of yield strength residual factor, which is defined as the ratio of the yield strength of a test specimen that is cooled after exposure to elevated temperature (e.g. F y, T, C N 2) to yield strength of un-notched specimen (SPR) at room temperature (F y, 20, S P R).
