Abstract
There are many ongoing efforts to develop sustainable, clean, efficient, and economical pathways to produce renewable energy sources to satisfy worldwide energy demands. Electrochemical conversion processes, such as water splitting, CO2 conversion and N2 electroreduction, have been considered as successful approaches to solve these energy issues. Over the past decade,..... More

Abstract
Cu-Ti alloys were strengthened by Cu4Ti intermetallic compound precipitation in a Cu matrix during aging. The Cu-3.5 wt% Ti(Cu-4.6 at% Ti) alloys without deformation and with uniform and non-uniform deformation were aged at 450 oC for various times after solution treatment at 885 oC. The uniformly and non-uniformly deformed alloys..... More

Abstract
The effect that forging routes (3 routes, A-C) exert on the development of deformation heterogeneity in AA1100 was theoretically performed using finite element analysis. Route A corresponded to a forging process that involved from 1 to 6 passes through multi-axial diagonal forging (MADF); Route B corresponded to a forging process..... More

Abstract
The hot crack resistance and mechanical properties of flux cored arc (FCA) welds were investigated with three kinds of welding consumables having different boron (B) and manganese (Mn) contents for high strength carbon steel. The hot crack resistance, measured from self-restraint testing, strongly depended on the amount of B in..... More

Abstract
Many important material properties of ferroelectric ceramics such as piezoelectric coefficient and hysteresis curve are governed by domain structures and their evolution processes. In the present work, domain wall motions in a near-morphotropic Pb(Zr,Ti)O3 under an external compressive stress were observed using in situ piezoresponse force microscopy (PFM). This specific.....

Abstract
Compact Endless cast and rolling Mill (CEM) processes were developed and used to fabricate steel products such as steel slabs. However, the coiling furnace in this process was very expensive, so a new layout was suggested. As the coiling furnace was removed, the interval among the slab heaters had to..... More

Abstract
Three 304L austenitic stainless steel feedwater heater (FWH) tubes used in pressurized water reactors (PWRs) were investigated in this study. By comparing metallurgical differences, such as microstructural features, micro-hardness, and circumferential residual stress of the failed and non-failed FWH tubes by stress corrosion cracking (SCC), factors which could affect SCC.....

Abstract
Both the mechanical properties and probability distribution of liquid phase sintered SiC (LPS-SiC) materials were investigated, based on a detailed analysis of their microstructures. In particular, the effect of the starting sizes of SiC particles on the characterization of LPS-SiC materials was evaluated. LPS-SiC materials were fabricated with a constant..... More

Abstract
Lack of understanding on the electrical properties of the solid electrolyte interface (SEI) has been one of the major hurdles for developing fast charging Li-ion batteries. Here, we report our preliminary experimental result on the measurement of the electrical resistivity of SEI using the direct-contact technique based on electron microscopy..... More
