Conducting a microscopic analysis of the powders obtained by electroerosion dispersion of waste of steel X13 [PDF]

open access: yesMATEC Web of Conferences, 2020
Alloyed steels and alloys containing a significant amount of non-ferrous metals are used for the manufacture of critical parts for various purposes, since it is the alloyed steels and alloys that possess a complex of high physicomechanical and other ...

Mechanical and wear behaviour of nanostructure TiO2–Ag coating on cobalt chromium alloys by air plasma spray and high velocity oxy-fuel

open access: yesJournal of Materials Research and Technology, 2019
Cobalt chromium alloys constitutes the base of one important group of biometallic with excellent mechanical properties. However, due to its non-bioactive and non-antimicrobial surface, cobalt chromium alloys are vulnerable to wear corrosive attack and ...

Carburisation of ferritic Fe–Cr alloys by low carbon activity gases [PDF]

open access: yes, 2011
Model Fe–Cr alloys were exposed to Ar–CO2–H2O gas mixtures at 650 and 800 °C. At equilibrium, these atmospheres are oxidising to the alloys, but decarburising (aC ≈ 10−15 to 10−13).

Influence of oxide films on primary water stress corrosion cracking initiation of alloy 600 [PDF]

open access: yes, 2006
In the present study alloy 600 was tested in simulated pressurised water reactor (PWR) primary water, at 360 °C, under an hydrogen partial pressure of 30 kPa. These testing conditions correspond to the maximum sensitivity of alloy 600 to crack initiation.

Use of nuclear physics methods for investigation of short-range ordering and defects in iron based simulatuing alloys [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2020
The changes of short range ordering and electron density were investigated by means of the nuclear gamma-resonance and the positron annihilation spectroscopies in model alloys containing tungsten, chromium, molybdenum, and vanadium used as dopants.

Cyclic oxidation resistance of rare earth oxide gel coated Fe-20Cr alloys

open access: yesMaterials Research, 2007
Rare earths (RE) have been used to increase high temperature oxidation resistance of chromium dioxide and alumina forming alloys. The RE can be added as elements (or oxides) to the alloys or applied as an oxide coating to the alloy surface. RE oxide gels,
