Effect of Y content on hot tearing susceptibility of MgZn₉Y_xZr_0.5 alloys

Cailiao gongcheng, 2019
Based on the Clyne-Davies model,the hot tearing susceptibility(CSC)of MgZn9YxZr0.5(x=1,2,4,6,mass fraction/%) was predicted.The microstructure and morphology of hot tearing regions of the alloys were observed by X-ray diffraction (XRD) and scanning ...

Microstructures and mechanical properties of zirconium-containing 7×××aluminum alloy prepared by selective laser melting

Cailiao gongcheng, 2021
The preparation of 7×××series aluminum alloy by selective laser melting technology (SLM) is hindered by hot tearing. Novel ZrH2 modified 7075 composite powders were prepared by the low-energy ball milling technology.

Study of the Properties of the AlSi9Cu3 Alloy Depending on the Ratio of Returnable Material in the Batch [PDF]

Archives of Metallurgy and Materials, 2020
Recycling of aluminium returnable material through its reuse is now an essential component of the production of aluminium alloy castings. The main goal is to find a suitable ratio of the primary alloy and the returnable material in the batch, thus ...

Bifilms and Hot Tearing of Al-Si Alloys

, 2016
Hot tearing is one of the most interesting defects that can be found during casting of aluminium alloys. The definition of this defects has some uncertainties such as “it does not always appear under apparently identical conditions” or “the defect is highly specific to certain alloys”.
