Hot Tearing Evaluation of Al-0.9Mg-0.7Si Aluminium-cast Alloy [PDF]

Archives of Foundry Engineering
This study aimed to evaluate the hot tearing susceptibility (HTS) of the Al-0.9Mg-0.7Si aluminium casting alloy, with a particular focus on how cooling rates and thermal stresses during solidification influence this phenomenon.

Experimental and numerical analysis of hot tearing susceptibility for Mg–Y alloys [PDF]

Journal of Materials Science, 2013
The influences of Y content and initial mold temperatures on the hot tearing susceptibility (HTS) of binary Mg–Y alloys were investigated using a constrained rod casting (CRC) apparatus, which is equipped with a load cell and data acquisition systems. The hot crack formation was monitored during CRC experiments.

Observation of Hot Tearing in Sr-B Modified A356 Alloy

Archives of Foundry Engineering, 2017
In this work, T-shaped mould design was used to generate hot spot and the effect of Sr and B on the hot tearing susceptibility of A356 was investigated. The die temperature was kept at 250°C and the pouring was carried out at 740°C.

Effect of Sn addition on hot tearing susceptibility of AXJ530 alloy

Materials Research Express, 2018
The effects of different Sn additions (0, 0.5, 1.0, and 2.0 wt%) on hot tearing susceptibility (HTS) of AXJ530 alloy were studied using 'T-shaped' hot tearing mold at a pouring temperature of 700 °C and a mold temperature of 200 °C and paraffin permeation method. The dendrite coherency temperature was obtained by means of differential thermal analysis (

On the interplay between intermetallic controlled growth and hot tearing susceptibility in Al-to-steel welding with additional interlayers

Materials & Design, 2019
The brittle behaviour of Fe/Al intermetallic compounds formed during dissimilar Al-to-steel welding is a major drawback for the mechanical integrity of the joint, particularly for thick intermetallic layers. In order to improve the toughness of the weld,

Effect of molybdenum on the hot-tearing susceptibility of the Ni-Cr-Mo-B system

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The paper presents data on the effect of molybdenum on the hot-tearing susceptibility of the Ni-Cr-Mo-B system when surfacing with nickel-based alloys. With a boron content of 2.5-3.2%, as well as low carbon and silicon content, the alloying elements, depending on a doping concentration, have different effects on the ...

Influences of Y Additions on the Hot Tearing Susceptibility of Mg-1.5wt.%Zn Alloys [PDF]

Materials Science Forum, 2013
The influences of Y (0.2, 2 and 4 wt.%) additions on the hot tearing behaviour of Mg‑1.5Zn alloys were investigated using a constrained rod casting (CRC) apparatus equipped with a load cell and data acquisition system. The initiation of hot tearing was monitored during CRC experiments. It corresponds to a drop in load on the hot tearing curves.
