was controlled by computer system. After continuous printing, a complex-shaped green body and some cuboid samples were obtained. These green samples were dried in a vacuum drying oven at 60 °C for 5 h. Lastly, the dried samples were sintered at 1200 °C for 120 min in a vacuum furnace. The detailed sintering process would be discussed later. Subsequently, heat treatment was carried out, which was designed......

For instance, Ni single crystals subjected to HE yielded strongly refined microstructures with an average sub grain diameter of approximately... extrusion were examined using the Vickers hardness (VH) measurement and were observed along the directions parallel and perpendicular to the direction of extrusion, as seen in Fig. 1(c). Here, ED, RD and TD......
sinter bonding was performed in air at 250-350 °C using a preform comprising copper formate particles to form a bondline that is sustainable at high temperatures. H2 and CO generated concurrently by the pyrolysis of copper formate at 210 °C during the sinter bonding removed the native oxide and other oxides grown on bulk Cu finishes, enabling interface bonding. Moreover, Cu produced in situ......
