Preparation of boron carbide stainless steel composites by spark plasma sintering

Fenmo yejin jishu
The B4C-stainless steel composites with B4C mass fraction of 4.00% were prepared by spark plasma sintering (SPS) method, using B4C microspheres and 304 stainless steel powders as the raw materials. The density of the composites was tested by the drainage

Creep of Reaction Sintered and Liquid Phase Sintered Sialon

Journal of the Mechanical Behavior of Materials, 1990
Creep experiments were conducted with 100—250 MPa stress at 1200-1450°C of Reaction Sintered (RS) Sialon A synthesized from Si3N4-AlN-Al203 and Liquid Phase Sintered (LPS) Sialon C, CI synthesized from Y203-A1N-Si02 systems. RS Sialon A, containing no liquid phase sintering aid, had better creep resistance than LPS Sialon C, CI.

Effects of Incorporating Β-Tricalcium Phosphate with Reaction Sintering into Mg-Based Composites on Degradation and Mechanical Integrity

Metals, 2021
For applications of biodegradable load-bearing implants, we incorporated 10 or 20 vol% β-tricalcium phosphate (β-TCP) into Mg-based composites through reaction sintering in the spark plasma sintering process.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Reaction sintering of silicon oxynitride.

Journal of the Japan Society of Powder and Powder Metallurgy, 1989
Silicon oxynitride (Si2N2O) ceramics were fabricated from equi-molar mixtures of Si3N4 and SiO2 with 5 wt % Al2O3 as a sintering aid by heating at 1650-1950°C for 1 h in 980 KPa N2. The initial stage of densification was due to the solution and repreci-pitation of Si3N4 through a liquid phase of SiO2-Al2O3 system.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...
