Hot tear susceptibility of aluminium–silicon binary alloys

International Journal of Cast Metals Research, 2010
AbstractHot tear susceptibility (HTS) of Al–Si alloys in the 0–5–3·0 wt-%Si has been determined using a constrained rod casting test and a quantitative index. Hot tear susceptibility was seen to decrease with increasing silicon content. Hot tear severity varied directly with solidification shrinkageβ, the non-equilibrium freezing range ΔT′, dendrite ...

Hot-tearing susceptibility of Al–Zn alloys

Russian Metallurgy (Metally), 2017
The modern concepts of the causes of hot tearing are considered and the influence of the solid fraction growth rate of an alloy is studied. The hot-tearing susceptibility (HTS) of binary Al–(5–73) wt % Zn alloys is investigated using backbone tests. The HTS is found to be maximal at ~25 wt % Zn.

Hot Tearing Susceptibility of Mg-Ca Binary Alloys

Metallurgical and Materials Transactions A, 2015
Hot tearing is known as one of the most critical solidification defects commonly encountered during casting practice. As most Mg alloys are initially prepared by casting, ingots must have superior quality with no casting defects for the further processing.

Hot-tearing susceptibility of Mg–9Al–xZn alloy

Materials Letters, 2002
Abstract Hot-tearing susceptibility of Mg–9Al– x Zn alloys is studied. Crack-ring molds were used to test the hot-tearing susceptibility. In situ thermal analysis, optical microscopy, scanning electron microscopy (SEM) and line scan were used to examine the hot-tearing behavior.

Hot Tearing Susceptibility of Magnesium–Gadolinium Binary Alloys

Transactions of the Indian Institute of Metals, 2012
Hot tearing susceptibility of Mg–Gd alloys are investigated using instrumented constrained rod casting (CRC) apparatus, and found that the susceptibility increases with increase in Gd content, and reaches a maximum at 2 % after which it decreases to a minimum with 10 % Gd.

Failure Analysis and Hot Tearing Susceptibility of Stainless Steel CF3M

International Journal of Metalcasting, 2018
Hot tear formation has been witnessed during the solidification of the ferrous alloy by pulling the columnar dendrites in the transverse direction. The hot tearing susceptibility of an alloy is influenced by solidification rate, microstructure and the stress/strain conditions. It is valuable to predict the occurrence of tearing in a casting.

Hot-Tearing Susceptibility of Ternary Mg-Al-Sr Alloy Castings

Metallurgical and Materials Transactions A, 2010
The susceptibility of Mg-Al-Sr alloys to hot tearing during permanent mold casting was investigated using constrained rod casting (CRC) in a steel mold. The alloys included Mg-xAl-1.5Sr and Mg-xAl-3Sr, where x = 4, 6, or 8 wt pct. The hot-tearing susceptibility (HTS) was determined based on the widths and locations of the cracks in the rods.

Effect of Y on the hot tearing susceptibility of 3Y2O3/Al5Cu composite

Journal of Alloys and Compounds, 2020
Abstract Hot tearing susceptibility (HTS) refers to the casting defect that existed owing to the appreciable shrinkage at the final stage of solidification. Present research studied the effect of Y on the HTS of 3Y2O3/Al5Cu composite. After 0.3%, 1% and 2% Y (in wt.%) added, the HTS value of 3Y2O3/Al5Cu composite decreased by 2.1%, 39.5% and 61.9 ...

Prediction of Hot Tearing Susceptibility for Mg-Zn-(Al) Alloys

Advanced Materials Research, 2012
It is importance to be able to predict the hot tearing tendency for multicomponent magnesium alloys. Hot tearing is one of the most common and serious defects that occurs during the solidification of commercial magnesium alloys. Clyne and Davies correlated the susceptibility-composition relationship in binary systems based on the concept of the ...
