Friction stir welding of Al-Al2O3 nanocomposite with bimodal size of alumina reinforcement produced by spark plasma sintering
Solid state joining of powder metallurgy (P/M) processed and sintered by spark plasma sintering through friction stir welding (FSW) was studied. The nanocomposites were prepared via mechanical milling followed by spark plasma sintering. The microstructural and mechanical of the joints were evaluated as a function of the different processing parameters such as rotating and advancing speeds of th...

متن کاملEffect of Thermal Cycle on Properties of Welding Heat Affected Zone
In this report T-T-T diagram and CCT-Curve from austenitizing temperature 1200•Ž were researched and then effects of preheat temperatures and welding thermal cycle on properties of heat affected zone were clarified to investigate weldagility of 21/4 Cr-1Mo steel and also we carried out a restraind crack test to investigate crack sensitivity of the steel. The results of experiments are summarize...
متن کاملEffect of Heat Input on Microstructure and Mechanical Properties in Friction Stir Welding of HSLA-60
High-strength low alloy steels are a class of steels used in applications that require high strength and good weldability, including ship hulls, gas pipelines and oil industry. One way to build parts is fusion welding that create areas with a large grain size in the heat-affected zone and increased susceptibility to hydrogen cracking. One way to solve this problem is to use solid state friction...
متن کاملNumerical Modeling of Heat Affected Zone Cracking Tendency during Laser and Hybrid Laser-Arc Welding Processes
A two-dimensional thermal elasto-plastic numerical model is developed by finite element method to analyze and compare the mechanical driving factor for heat affected zone (HAZ) liquation cracking during laser welding and hybrid laser-arc welding techniques. Calculations of transient temperatures and cooling rates are used in conjunction with solidification theory to analyze weld pool characteri...
