Numerical analysis on solidification cracking susceptibility of type 316 stainless steel considering solidification mode and morphology computer simulation of hot cracking by solidification/segregation models

Welding International, 2018
The two-phase solidification model was constructed considering the solidification mode and morphology. The effects of the solidification mode and morphology as well as δ-ferrite on the solidification cracking susceptibility of austenitic stainless steels

Solidification behaviour of undercooled peritectic Fe81.68Co18.32 alloy

Journal of Alloys and Compounds, 2009
Abstract Rapid solidification of undercooled peritectic Fe 81.68 Co 18.32 alloy was investigated using fluxing method. With the increase of initial melt undercooling (Δ T ), different microstructures were observed. For low Δ T , a typical peritectic microstructure, if Δ T exceeded a critical value, 177 K, metastable phase was observed in the as ...

Solidification behaviour under intensive forced convection

Materials Science and Engineering: A, 2005
Abstract Solidification behaviour of AZ91D Mg-alloy and 357 Al-alloy under intensive forced convection in the rheo-die-casting process, was investigated experimentally to understand the effects of the intensity of forced convection and shearing time on the nucleation and growth behaviour.

Solidification behaviour of squeeze cast aluminium composites

AIP Conference Proceedings, 2020
The effect of die temperature on the solidification behaviour of aluminium mixed ceramic cast samples are studied. The samples are prepared by squeeze casting method. The die temperatures are assigned in this work from 220 - 280°C and the preparation of aluminium in liquid state of temperature is 850°C, respectively.

Solidification Behaviour of a H21 Tool Steel

Advanced Materials Research, 2014
Solidification behaviour of a H21 tool steel has been studied. The aim of this work is to give better understanding of the as cast microstructure of the steel. The investigated H21 tool steel was made using induction vacuum furnace with air cooling. The microstructure observation was carried out using optical and electron microscopy.

Solidification Behaviour of Al–SiC Composite Foam

Transactions of the Indian Institute of Metals, 2018
This paper describes the solidification behaviour of Al composite melt in the narrow cell wall region in Al foam. Aluminium alloy foams prepared through melt route essentially involve entrapment of gaseous phase in a high viscous liquid followed by solidification.

Solidification behaviour in plasma are welding

Sadhana, 2001
Melting and solidification behaviour in the deep penetrution welding process is different from that in conventional welding process in deep penetration processes there is keyhole formation and the full thickness of the plate receives the are heat input unlike conventional processes in which the heat input is received only by the surface nodes.

Solidification behaviour of organic nonlinear optical crystals

Progress in Crystal Growth and Characterization, 1988
Abstract A representative rather than exhaustive review has been given on the solidification behaviour of organic nonlinear optical crystals. Many of the developments reported here represent quick experimental responses to the rapid theoretical advances made in the field of nonlinear optics. The article is divided into four parts.

Numerical Modelling and Experimental Study of Solidification Behaviour of Al-mg2si Composite Sheet Fabricated Using Continuous Casting Route

ASME Journal of Heat and Mass Transfer, 2023
Owing to manufacturing challenges, the fabrication of thin sheets of metal matrix composites has been an area of concern for sheet manufacturers. Converting a billet of composite into a sheet using rolling and extrusion is quite energy-intensive and ...

The Solidification Behaviour of Al-Mn Melts.

Journal of Non-Crystalline Solids, 1990
Abstract Small liquid droplets of Al 1−x Mn x (x = 8, 11.8, 17, 21.5 at.%), with diameters in the range 250 μm – 1000 μm have been undercooled and solidified by containerless processing during free fall in a drop tube. Undercoolings larger than 150 K have been estimated. The solidified droplets show crystalline phases and metastable quasicrystalline
