Han et al. [14] established 1/3-scale precast segmental assembled double-column piers with replaceable and proportionally reduced energy dissipation devices outside the bottom of piers. By pseudo-static testing, it was found that external energy dissipation devices improved the energy dissipation ...
Corrosion test results indicated that the lowest corrosion rate (2.6 × 10−8 mpy) is related to the sample with the highest level of efficiency. Keywords: MEW operation; WC-Co cermet electrode; 36Cr-Ni-Mo4 steel; spark energy; roughness; corrosion 1. Introduction 36Cr-Ni-Mo4 steel is...

The loading rate of the testing machine was set as 0.5 MPa/s until failure of the cubic and prism specimens occurred to obtain f cu and f c. When testing f ts, the loading rate was 0.05 MPa/s, and f ts is calculated using Equation (1). fts = 2F πA = 0.637 F A (1) where...

However, in this process, scale formation and surface decarburization occur, caused by surface oxidation of the steel when heated in excess of 900 ◦C. In turn, to solve this issue, Al-Si hot-dipped coating is typically performed [4–7]. However, when an Al-Si–coated boron steel ...
