Multi-Track Friction Stir Lap Welding of 2024 Aluminum Alloy: Processing, Microstructure and Mechanical Properties

Friction stir lap welding (FSLW) raises the possibility of fabricating high-performance aluminum components at low cost and high efficiency. In this study, we mainly applied FSLW to fabricate multi-track 2024 aluminum alloy without using tool tilt angle, which is important for obtaining defect-free joint but significantly increases equipment cost. Firstly, systematic single-track FSLW experimen...

Microstructure Modelling of Hot Deformation of Al-1%Mg Alloy

This study presents the application of the finite element method and intelligent systems techniques to the prediction of microstructural mapping for aluminium alloys. Here, the material within each finite element is defined using a hybrid model. The hybrid model is based on neuro-fuzzy and physically based components and it has been combined with the finite element technique. The model simulate...

Characterization of the Dendritic Microstructure of Investment Cast Alloy 718

The as-cast alloy 718 shows a multiphasic structure which consists of dendrites, carbides and Laves phases. The amount, size, shape, and dispersion of these phases affect the properties and the processing which follows, This structure was characterized by measurements of volume fraction, size, dispersion, and shape factor of carbide and Laves phases. Secondary arm spacing and Vickers hardness w...

Microstructure and High Temperature Deformation Behavior of Cast 310S Alloy

High temperature deformation behavior of cast 310S stainless steel has been investigated in this study by performing tensile and compression tests at temperatures from 900 to 1200C. Rectangular ingots of which the dimensions were 350×350×100 in millimeter were cast using vacuum induction melting. Phase equilibrium was calculated using the FactSage®, thermodynamic software and database. Thermal ...
