S T, ZHANG G A, JIANG F. Microstructural evolution and mechanical properties of hypereutectic Al-Si alloy processed by liquid die forging [J]. Bulletin of Materials Science, 2014, 37(5): 1153-1157. [5......
through a graphite die/punch set-up that contains the starting powder. The process permits simultaneously a high pulsed DC current (10 kA) flow at low voltage (10 V), in combination with a uniaxial.... 10 g of the prepared powder mixture was poured into a graphite cylindrical die with an inner and an outer diameter of 32 and 66 mm, respectively. Sintering was performed using SPS (HP D25/1, FCT......
was cast into a steel die placed below the furnace. The used casting temperatures were 700 °C (fully liquid, hence stir casting) as well as 610 and 601 °C (semisolid, hence compocasting), corresponding......
; m is the mass of a powder compact; r is the inner radius of steel die; h0 is the final height of the compact; L0 is the final displacement of the beam; Li is the displacement of the beam when pressure is Pi; l0 is the final displacement of the beam when pressure is P and there is no powder in die; li is the displacement of the beam when pressure is Pi and there is no powder in the die. As Eq. (2......
with different ratios of a/b It is worth mentioning that the die casting process may be used for the mass production of the tapered structures shown in Figure 1. For the small quantities, the decagonal......
previous studies [2,9,13,26] using a high energy ball mill, Fritsch P7. The milled powders were pressed uniaxially at 2.5×108 Pa into circular discs (d=20 mm) by a rigid steel die. Aiming to obtain a high......
