Sintering Behavior of 45S5 Bioglass®

Key Engineering Materials, 2007
In this study, we report on the effect of Bioglass® structural transformations on its sintering behaviour. In a previous paper, we showed that while heating up to 1000°C, five successive transformations occur: glassy transition, phase separation, two crystallization processes and a second glassy transition.

Mechanical Behavior of Non Sintered and Sintered Steel Wool

Advanced Materials Research, 2008
Entangled materials are similar to cellular materials, with regard to their low density and discrete architecture. In this work steel wool (sintered in a furnace for various time at two temperatures) and non sintered steel wool are investigated. Experimental mechanical compression tests were performed on both materials.

Fatigue Behavior and Fracture of Sintered

Materials Science Forum, 1998
Pores sizes were systematically changed by varying size particles, compaction pressure and sintering time in specimen fabricated from ASC 100.29 powder. The sintering atmosphere was hydrogen. Fatigue life curves were obtained under axial loading. It is concluded that microcrack are initiated in pores of great size being associated with irregular ...

Sintering behavior of niobium carbide

Soviet Powder Metallurgy and Metal Ceramics, 1974
1. The kinetics of the sintering of niobium carbide is largely determined by the presence in the latter of iron, which is picked up during milling in units with steel balls. Activated sintering was found to be exhibited by powder containing, in the starting condition, as little as 0.3 wt.% of iron. No upper limit of the activating action of iron has

Sintering behavior of lead metaniobate

Ferroelectrics, 1997
Abstract The densification behavior and microstructure development were examined on low and high temperature modifications of PbNb2O6. The phase transformation occurred during the sintering of the low temperature form and increased the grain growth rate, resulting in the reduction in densification rate.

Sintering behavior and mechanical properties of sintered ceramics based on spodumene tailings

Journal of Central South University, 2021
In this study, ceramics was prepared by slip casting (no pressure was used during shaping step) and atmospheric pressure sintering with low-melting point glass (LPG) powder as the binding material to facilitate the transformation of spodumene flotation tailings (SFTs) into ceramics at lower temperatures.

Sintering Behavior of Lead Oxide Ceramic Prepared by Microwave Sintering

Advanced Materials Research, 2014
The structure material corrosion in liquid lead or lead-bismuth eutectic (LBE) is a tremendous limitation of the development of lead cooled fast reactors and accelerator driven sub-critical system (ADS). Keeping a certain oxygen concentration can prevent the steel pipe from corrosion by LBE. Through dissolution and precipitation of PbO ceramic has been

A new approach to sintering and boriding of steels “Boro-sintering”: Formation, microstructure and wear behaviors

Surface and Coatings Technology, 2020
Abstract In this study, sintering and boriding methods are applied as a single step, and it is aimed to gain time and economic advantage. For this purpose, powder mixtures prepared in suitable compositions were subjected to sintering and boro-sintering processes.

Percolating behavior of sintered random packings of spheres

Powder Technology, 2012
Abstract This study investigates the effects of sintering in random composite packings of spherical particles, with focus on structures with relatively low densification where the sintering is used to obtain desired catalytic and transport properties.

UO2-Gd2O3 Sintering Behavior

1978
The sintering characteristics of UO2-Gd2O3 Mixtures were investigated over the range 0 to 20 wt% Gd2O3. It was observed that as little as 0.5 wt% Gd2O3 will reduce the sinterability of powder mixtures. This effects is Correlated to stoichimetry changes induced by the ionic substitution of Gd+3 for U+4 in the structure.
