Evidence of underlying structural similarities of amorphous materials
To guide the ABED experiment, we simulated ABED patterns from local atomic configurations of amorphous HfO2. For this purpose, we first prepared ten structural models of amorphous HfO2 with 324 atoms by ab-initio MD simulation and characterized…

Characterization of joining copper rods by upset technique and investigating the effect of preheat treatment on the weld characteristics
The impact of power on the welding process
Generally, weld characteristics are considered as a function of welding time, welding power, applied pressure, and the heat dissipated in the weld for each welding position of the machine. In this method,…
