The aim of this study is to investigate fracture toughness of alumina-mullite composites produced by infiltration process. Alumina-mullite composite samples were fabricated using a hydrolyzed ethyl silicate sol (TEOS) which ...

In the present study, alumina ceramics containing 99% and 99.8% alumina, which has been studied and indicated reliable performance in vivo and vitro experiments for another ideas before this study, were subjected to the ...

The present study reports on kinetics of bonded AISI M2 high speed steel. Boronizing thermochemical treatment was carried out in a solid medium consisting of EKabor powders at 850 degrees C, 900 degrees C and 950 degrees ...

In this study, kinetics of borides formed on the surface of 31CrMoV9 and 34CrAlNi7 steels borided in solid medium consisting of Ekabor II at 850-900-950 degrees C for 2, 4, 6 and 8 h were investigated. Scanning electron ...

A technologically interesting characteristic of boriding is the production of a hard, wear-resistant coating layer on the steel substrate. In this study, case properties of borided AISI W1 steel-has been investigated by ...

The present paper describes producing alumina ceramic matrix composites reinforced with nickel at ratios of 1 % to 7 % by weight and their resultant mechanical and electromagnetic properties. In this study powder metallurgy ...

A series of experiments was performed to evaluate some mechanical properties of boronized AISI W4 steel. Boronizing was carried out in a solid medium consisting of EKabor powders at 850, 950 and 1050 C for 2, 4, 6 and 8 ...

In this study, some properties of biomimetic synthesized hydroxyapatite by using different sources of calcium were investigated. Biomimetic synthesis of hydroxyapatite was carried out in microwave oven using 1.5 simulated ...
