“…All these recorded data are used to plot the graph between compressive stress and compressive strain using standard methodology [9,16,17,21]. The Young modulus, the plastic collapse stress, the plateau stress, the densification strain and the [17], Acrowax [9] and ammonium bicarbonate [16] as space holder to get porosity in the range of 40% to 70%. They examined that the space holder also affects the mechanical properties [16].…”

“…In case of powder metallurgy, porosity in metal is created using different methods such as loose powder sintering [13], gas entrapment method [14], replication method [15] and space holder method (the sintering of matrix alloy powder and space holder powder mixture after cold compaction) [5]. The porosity and pore size of metallic foam could be controlled by the control of amount of space holder material and its particle size of space holder [16]. Some materials like NaCl [17], saccharose [18], carbamide [19], magnesium [20], ammonium bicarbonate [16,21] were used as space holder.…”

Open cell Ti 6 Al alloy foams of varying porosity fractions have been made using ammonium bicarbonate as space holder through powder metallurgy route. In order to provide the sufficient strength in green compacts 2% of wt.% PVA solution was mixed with elemental metal powder and NH 4 (HCO 3 ) particle prior to cold compaction. Green pallets were sintered at three stages at three different temperatures 600°C, 800°C and 1100°C. XRD and EDX analyses confirmed that no residue of space holder remained in the sintered foam samples. The compressive deformation behavior of Ti 6 Al alloy foams with varying relative densities was conducted under different strain rates (0.01, 0.1, and 1.0 s -1 ). The plateau stress, the Young's modulus and the energy absorption of the foam increase with increase in the relative density following power law relationships. But the densification strain decreases with increases in relative density following a linear relationship. The strain rate sensitivity and the strain rate sensitivity parameter of these foams were also examined, and it was found that the strain rate sensitivity parameters were varying in the range 0.034 to 0.078.

Solid State Porous Metal Production: A Review of the Capabilities, Characteristics, and Challenges

et al. 2018

View full text Add to dashboard Cite

Porous metals have been under development for nearly a century, but commercial adoption remains limited. This development has followed two primary routes: liquid state or solid state processing. Liquid state foaming introduces porosity to a liquid or semi‐solid metal, and solid state foaming introduces porosity to a metal, which is fully solid. Either method may create pores by internal gas pressure or introducing metal around a template directly control porosity. Process optimization and commercial output has been primarily related to liquid state methods, as solid state processing is often more complex, diverse, and with lower throughput. Solid state methods, however, are often more versatile and offer greater control of pore characteristics. Ongoing advancements in solid state foaming have allowed for a wide array of metals and alloys to be made porous and the three‐dimensional structure to be precisely tailored. In general, solid state processing remains limited to niche applications, often with modest dimensions (cm scale). “Traditional” solid state processes are being further refined and extended, and continuing developments to reduce cost, increase output, and control pore characteristics are likely to produce important advancements in coming years. The extensive variability of pore quantity and morphology makes solid state processes suitable, and often preferable, for an assortment of functional and structural applications, with electrodes and biomedical devices being among the most popular in current research. Various techniques for introducing porosity, the way these methods are applied, important considerations, typical outcomes, and current applications are reviewed.
