Summary: This article presents a method and results of producing alumina-tantalum composites through cold isostatic pressing from commercially available raw materials. The study found that the densification of the composites can vary with different pressure and temperature conditions. The formation of tantalum carbide and the incorporation of oxygen into the tantalum lattice were also observed.

Summary: In this study, high-density LCSMO ceramics were successfully obtained using the sol-gel method followed by cold isostatic pressing (CIP) at 250 MPa. The investigation on the effects of sintering temperature (T-S) on the structure, electrical, and optical properties showed that the best electrical performance was achieved at 1450 degrees C, with improved electrical behavior due to the high densities of samples processed by CIP. The change in T-S significantly influenced electrical behaviors but had little effect on the structural and optical properties of LCSMO ceramics.

Summary: This study aimed to improve the thermal conductivity of stainless steel (SS) matrix by fabricating a metal composite SS-Cu using laser powder bed fusion. The effect of process parameters on the microstructure of SS-Cu samples was investigated and the factors influencing the thermal conductivity were discussed. The thermal conductivity and mechanical properties of the SS-Cu composite were measured at room temperature and 300 degrees C. The optimized parameters led to significant thermal conductivity enhancement, but reduced the ductility of the SS-Cu composite due to the presence of unmelted powder particles. Annealing played a key role in enhancing the thermal conductivity by promoting phase separation, partial melting of Cu, and formation of a continuous network of Cu surrounding SS.

Summary: In this study, a method to create surface-microcracks in a Zn foil by 200 MPa cold isostatic pressing is proposed. The proposed method effectively alleviates the dendrite growth and side reactions during the repeated Zn plating and stripping, leading to high-performance zinc anodes for zinc-ion batteries. The 200 MPa Zn||Zn symmetric cell and 200 MPa Zn||VO2 full cell show excellent cycling stability.

Summary: This paper investigates the capsule free hot isostatic pressing (HIP) process of alumina and yttria-stabilized zirconia ceramics and provides important insights. It is found that rapid heating does not affect pore closure behavior or restrict grain growth compared to conventional heating. The study also reveals the optimal HIP conditions for producing nearly fully dense compacts with minimal grain growth. Additionally, applied pressure does not enhance grain boundary mobility during the HIP process.

Summary: This study found that the argon content near the surface of the AM-material increased significantly during HIP, while the bulk content remained unchanged. Rough surfaces, time in HIP, and oxidised surfaces prior to HIP were all found to aggravate argon pick-up. Therefore, critical components should be machined, blasted, ground, or polished after HIP, or possess non-oxidised surfaces prior to HIP to mitigate any risk of a decline in material performance.

Summary: Cold spraying was utilized for the deposition of AlMgScZr alloy with low-porosity deposits successfully produced. Heat treatment and hot isostatic pressing (HIP) were performed to homogenize the structure, leading to significant improvement of ultimate compressive strength and the strain at failure of the deposits.

Summary: Cold isostatic pressing is a powder-based technology used for near-net-shape production of metal and ceramic components. Despite being more commonly used with ceramics, recent developments have led to its increasing use in high-performance metal part manufacturing. The process offers advantages such as solid-state processing and low tooling cost, making it viable for niche applications in aerospace and automotive industries.

Summary: Resistive memory devices based on metal-free phthalocyanine and sandwiched dyphthalocyanine have been successfully prepared and their performance is affected by interlayer thickness and crystalline structure. The devices exhibit high ON/OFF current ratio and long retention ability, and the electrical conduction behavior follows the space charge limited conduction mechanism. This study is important for designing advanced resistive memory devices and understanding their working mechanism.

Summary: In this study, cold spray additive manufacturing technology was used to produce composite AA7075 deposits reinforced by silicon carbide particles. Different heat treatments and capsule-free hot isostatic pressing were used to homogenize the structure of the composite. The presence of SiC in the composite influenced the distribution of hardening phases in AA7075 during heat treatment.

Summary: The effect of capsule-free hot isostatic pressing (HIP) on the porosity and mechanical properties of different cold spray deposits was evaluated experimentally. The HIP post-treatment significantly decreased the porosity of 316L and pure titanium deposits, while the densification effect on porous Ti6Al4V deposits was less pronounced. Mechanical properties, including tensile and compressive strength, were improved after HIP treatment, with an explanation given for the changes in material diffusion and microstructure during the HIP cycle.

Summary: In this study, the hot isostatic pressing (HIP) treatment effectively reduced the porosity and improved the mechanical properties of binder jetting (BJ) fabricated 316L stainless steel. The HIP treatment increased the relative density and decreased the mean diameter of internal closed pores and internal porosity. The mechanical properties, including tensile strength and elongation, were significantly enhanced due to the reduction of porosity. The mechanical properties of BJ 316L sintered under nitrogen and treated with HIP were even superior to those of the direct powder HIP components.

Summary: Powder hot isostatic pressing (HIP) is an effective method for the near-net-shape manufacturing of titanium alloy parts. This study investigates the microstructure characteristics and mechanical properties of HIPed titanium alloys. The results show that the microstructure and mechanical properties vary with different HIP temperatures, with higher temperatures resulting in larger grain size and reduced tensile strength and elongation but increased fracture toughness.

Summary: This study investigates the influence of substrate temperature on the amorphous structure and spontaneous orientation polarization (SOP) of Alq(3) films, which in turn affect the performance of organic light-emitting diodes (OLEDs). The presence of SOP improves electron injection and increases current in OLEDs, while increasing the substrate temperature for Alq(3) deposition leads to higher external quantum efficiencies and improved operational stability of OLEDs.
