Effect of Temperature on Damage Evolution of Cr25Ni35Nb Alloy Subjected to Combined Mechanical and Environmental Degradation

open access: yesHigh Temperature Materials and Processes, 2015
Due to combined mechanical and environmental degradation, i.e. coupled creep and carburization, Cr25Ni35Nb alloy often fails prior to the expected design life.

Lost pattern complex composition effect on steel casting structure and properties

open access: yesMetalurgija, 2021
One of the ways to produce high-quality castings at relatively inexpensive costs is lost foam casting. However, the existing problem of surface carburization due to the burnout of the polystyrene pattern and general contamination of the near-surface ...

Reliable Carburization of AISI H13 Steel : The Impact of Preoxidation

open access: yes, 2020
Case hardened Uddeholm Orvar® Superior (Orvar) has the potential to replace currently used materials in shafts inside transmissions, which would lower the overall weight and thus result in lower fuel consumption while maintaining the necessary mechanical

Effects of carburization process on the mechanical properties of carburized mild steel [PDF]

open access: yes, 2013
Due to the complexity of parameters in carburizing, there has been relatively little work on process variables during the surface hardening process. This work focuses on the effects of carburization process on the mechanical properties of carburized mild

Cyclic carburization-oxidation behavior of Hastelloy-X at 1000°C

open access: yes, 2018
Cyclic corrosion, consisting of carburization in Ar+4% CH4+3% H2 for 1 h and oxidation in air for 1 h, of Ni-base in a wrought alloy, Hastelloy-X, was investigated at 1000°C to understand the significant metal loss occurring in fuel injection nozzles of ...

An investigation of carburization resistance performance of ethylene furnace tube alloys [PDF]

open access: yes, 2011
Carburization tests and analysis were performed on some samples of radiant tube alloys of ethylene furnaces at three petrochemical plants. These tubes had undergone carburization in service with some losing their structural integrity.

Isotope Ratio Measurements of pg-size Plutonium Samples using TIMS in Combination with "Multiple Ion Counting" and Filament Carburization

open access: yes, 2009
A new sample preparation procedure for isotopic measurements using Thermal Ionization MAss Spectrometry (TIMS) was developed which employs the technique of carburization of rhenium filaments. Carburized filaments were prepared in a special vacuum chamber
