Research on High Performance Fe3Si-Si3N4-SiC Composite Used for Blast Furnace
Excellent Fe3Si-Si3N4-SiC composites were successfully prepared with FeSi75 and SiC as main starting materials by nitridation reaction(at 1300°C for 8Hrs). The material properties were studied; the ferrosilicon nitridation mechanism was analyzed through chemical thermodynamics; phase composition, microstructure, corrosion resistance of products were also investigated. The results are shown that...
متن کاملTensile Creep and Creep-Recovery Behavior of a SiC-Fiber─Si3N4-Matrix Composite
The tensile creep and creep-recovery behavior of a unidirectional Sic-fiher/Si,N,-matrix composite was investigated at 1200°C in air. A primary objective of the study was to determine how various sustained and cyclic creep loading histories would influence the creep rate, accumulated creep strain, and the amount of strain recovered upon specimen unloading. The key results obtained from the inve...
متن کاملDiametral tensile strength and Vickers hardness of a composite after storage in different solutions.
This study evaluated the Vickers hardness (VHN) and diametral tensile strength (DTS) of the composite Z100 (3M ESPE) cured with: Quartz-Tungsten-Halogen light curing unit (QTH) (700mW/cm2- 40 s) and Argon laser (1,000mW/cm2- 10 s). Specimens of 2 mm depth and 8 mm diameter were immersed for 30 days at 37 degrees C in different storage means: water, alcohol, acetic acid, propionic acid and dry (...
متن کاملInvestigation of Glass- Steel Slag Foam Composite Sintering in Presence of SiC
Amorphous steel slag was blended with different concentrations of waste glass (20, 40, 50, 60, 70 wt.%) and SiC to obtain a composite. According to Hot Stage Microscopy images, slag-glass composite contractions started at 1050 ºC. scanning electron microscope micrographs of slag-SiC (foaming agent) composite revealed tunnel-like porosities of 500 to 1000 microns. Gaseous products of carbide dec...
متن کاملLow-Load Vickers Microindentation Hardness Testing
ADVANCED MATERIALS & PROCESSES • APRIL 2012 I n 1925 in the UK, Smith and Sandland developed an indentation test that used a squarebased pyramidal-shaped indenter made of diamond[1]. The test was developed because the Brinell test (introduced in 1900), which (until recently) used a round hardened steel ball indenter, could not test steels harder than ~450 HB (~48 HRC). They chose this shape wit...
