Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Analysis of defects in a twin roll cast Mg‐Y‐Zn magnesium alloy

Engineering Reports, 2022
Twin roll casting (TRC) enables the production of magnesium strips in an economic manner. TRC has enormous potential for the production of thin strip material from magnesium alloys. However, a range of defects may arise during casting.

Study on neural network proportional-integration-differential (PID) control strategy of the molten metal pool level in the twin roll casting process

Metalurgija, 2020
In the twin-roll casting process, how to accurately control the molten metal pool level is a key problem to produce high quality strip. In this paper, the mathematical model about the pool level control is set up based on the process characteristics ...

Alleviating segregation and enhancing tensile properties of Inconel 718 superalloy by twin-roll casting and two-stage cold rolling

Journal of Materials Research and Technology, 2022
A novel processing route involving twin-roll casting and two-stage cold rolling was proposed to manufacture Inconel 718 alloy. Due to the sub-rapid solidification rate (412.5 °C/s) of as-cast strip, the element segregation can be alleviated and the ...

Characterisation of semi-solid deformation behaviour of aluminium-copper alloys via combined x-ray microtomography and nite element modelling

, 2009
The production of aluminium sheet is expensive and energy intensive despite the reduced environmental impact during use. Twin roll casting is a method of directly producing aluminium alloys in near net shape directly to sheet at a fraction of the ...

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Homogenization of twin-roll cast A8006 alloy

Transactions of Nonferrous Metals Society of China, 2012
Microstructure and hardness of twin-roll casting (TRC) process and direct-chill casting (DC) for A8006 alloy with and without homogenization were investigated by means of scanning electron microscopy (SEM), X-ray diffraction analysis and Vickers hardness measurement.
