]. The debinding atmosphere and the conditions should be controlled strictly because the stainless steel powder is easy to oxidize. And the polyurethane sponge has the urethane structure to resist.... Other materials were polyurethane sponge (0.8 pore/mm) and polyvinyl alcohol. The preparation process of stainless steel foam precursor with 3-D open-cell network structure could be seen in Ref.[9......
materials (e.g., polystyrene foam board, rubber, plastic, and sponge) are generally applied as boundary conditions. Thus, the two most typical materials mentioned above are selected as test objects... of 5 cm (Figure 1(b)). 3) For the foam board boundary, a 4-cm-thick polystyrene foam board is placed between the soil and model container (Figure 1(c)). 4) For the sponge boundary, a 4-cm-thick rubber......
produce spherical powder, but its diameter is coarse and the cost is high. The HDH is another important preparation method for titanium powder [10]. During HDH, the sponge titanium reacts with hydrogen..., the oxygen in powder can lead to balling phenomenon, which worsens the forming quality. Usually, the raw material used for HDH process is sponge titanium. The oxygen content in sponge titanium......
acts as a neutral ligand coordinated with Pd(II) via thiazolyl N atom and forms Pd Cl2(ABSO)2 at low acidity.

with Al-3B and Ti sponge. When the master alloy is prepared at 850 °C, a kind of TiB2 particle agglomeration forms with a size larger than 5 μm. The TiB2 particles change to layered stacking... master alloys was studied. 2 Experimental A series of Al-5Ti-1B master alloys were prepared by different processes (Table 1). 99% KBF4 and K2TiF6, 99.8% Ti sponge, 99.7% commercial pure Al and Al-3B......
